Form Access Checker in new Power Apps Form Designer | Model-Driven Apps in Dynamics 365

Most of us have been used to using the classic form designer as of now. And the Power Apps UI which is in https://make.powerapps.com/ has some important new features.

We create forms and we then have to explicitly make sure we have assigned them correct Security Roles and added them to the Apps correctly.

So the new Power Apps Form Designer has a very useful feature called as Form Access Checker. Let’s look at it

A Form & An App

  1. Let’s say we have a custom/Unmanaged Form called as ‘Management Form’.

  2. And an App called as ‘Management App’.

  3. And it has Contact entity with 2 Forms added.

  4. And here are the 2 forms – Contact (OOB) and Management Form (Custom)

Form Access Checker

The Form Access Checker answers 2 questions at once – Let’s look at this feature

  1. Open the form and go to Form Settings.


  2. In the Form Properties, look for Form access checker.


  3. Now, select the Security Role you want to check for and then the App you want to check. The Form Checker will show the Forms which satisfy either and both the criteria.


    Now with only Salesperson role, below are the forms which are applicable. Note that the App is not yet selected.

  4. Now, if you choose the App – the Form that matches both these will be selected.

  5. And it’ll show only the Forms which are applicable to both criteria. (Notice that the form we added in the Management App didn’t show up)

  6. Now, let’s give the Management Form we added Salesperson Security Role and see it satisfy the above criteria. You can now assign Roles to a Form within the Form designer itself.

  7. And if you check again, you’ll be able to conclude that the App we are looking for has both these forms for the Security Role you want to check

Multi-select Items from Gallery and adding/removing them from Collections | Power Platform

Now, let’s say you want to be able to select a few Gallery Items and the same should be populated to a Gallery and even from Collection as well.

You can use this scenario if you want to create a Collection of some GUIDs/Account Names and then take separate action on it or handle it in some other context.

Add Check box in a Gallery

Let’s take a simple example-

  1. I added a Check Box in a simple Gallery list.


  2. Align as per your preference. It also comes with a Default “Option” label which you can remove.


  3. Now, there are 2 properties which you can use to add to a Collection and remove from the same collection.
    Let’s look at the first one – OnCheck


  4. Under OnCheck function, I’ll add the current item to the Collection (A new collection will be created if not already created)
    Blue denotes function used to create a Collection. Collect() function – Microsoft Documentation on the Collect() function – https://docs.microsoft.com/en-us/powerapps/maker/canvas-apps/functions/function-clear-collect-clearcollect?WT.mc_id=DX-MVP-5003911
    Green arrow denotes the name of the Collection I’m creating.
    Red arrow denotes the current Item from the Gallery control and the Account Name field which I want to populate in my collection.
    This will add the Account Name of the record to the Collection once the Check box is checked.


  5. Under OnUncheck function, I’ll add the formula to remove the current Item from the Collection.
    Blue denotes the function used to remove a value from the Collection. Microsoft Documentation of the same is here – https://docs.microsoft.com/en-us/powerapps/maker/canvas-apps/functions/function-remove-removeif?WT.mc_id=DX-MVP-5003911
    Green arrow denotes the name of the Collection from which I have to remove the value.
    Red arrow denotes the current Item which I had added to the Collection when the Box was checked. It’ll use the same reference.
    This will Remove the Account Name which was added to the Collection when the checkbox was checked.


    For simplicity, I’m taking Account Names to show in the Collection, you can create a structure in Collection and map Item values as per your needs.

Changes in Collection (Using Data table to visualize)

Just to show/visualize how the Collection will look when I interact with the Check boxes on the Gallery, I’ve added a Data table to keep the demonstration simple.



And populate the Items with the Collection’s Value. Because all the Account Names we added to Collection while marking Check box as Checked will fall under .Value

Working

As you select and unselect items from the Gallery, they are added to and removed from the Collection which is seen in the Data Table below.

Hope this helps!!

Setting Correct Default Mode for Forms in a Canvas App | [Quick Tip]

If you are new to creating a Canvas App and you’ve just added a Form and when you try to run and test the same in the browser itself, you don’t see it.

So let’s say you’ve put a form like this

And all you see is this –

So this happens based on the Default Mode and whether the context is passed to the form depending on the type or not.

Default Mode

There are 3 Default Modes for a form and it’s critical which one should be used when –


1. Edit – To be used if you are creating a new record. While using this mode, make sure the Item (from a data source is passed to the Form itself. Else, you’ll see the same error message as above and won’t see a blank form in that case.)
The Item property should be pointed to pick .Selected i.e. typically, <GalleryName>.Selected.


Context of a record i.e. a Row should be passed on to this form for Edit mode i.e. an existing row to be passed on to this Form from the preceding Gallery/Table control (or any data source based on your implementation). For example – The context I send to the form looks like this.
The last parameter i.e. <GalleryName>.Selected is placed on the select button so that once clicked, it’ll send the record context over to the form so that the form is displaying the selected record (which is picked from Item property in the above screenshot)

2. New – New should be used if the Form you’ve inserted isn’t coming as a result of populating a selected record. But you will enter new values and Submit it the first time.
Once New is selected, the form will correctly render for you when you test or run the App once correct Mode is selected (i.e. you don’t intend to pass any context to the Form)

3. View – In this view, fields will not be visible and instead the data will be a result of the selected item from the List/Gallery view it is coming from i.e. a Data Row which will populate this form. This will be a Read-Only view.
Another form example where View is selected, fields won’t show up but this form would need Context to be passed to it just like in the New mode.

Hope this quick tip was useful.

Rating Control to represent data from Dataverse in a Canvas Power App | Power Platform

Although, you can use Text based controls to represent data as is in a Canvas Power App. So why not go an extra mile to make it look more intuitive.

Scenario

Let’s say there are Accounts and you have some kind of Compliance Ratings on them to represent compliant they are based on certain criteria. Could be a Numeric value or Decimal value. But Rating Control represents only in Numeric i.e. Whole Numbers.

So, for this example, I’m using a Rating field which is of type Whole Number in Dynamics 365 on Account entity.

And the complete Dataset looks like this in Dynamics 365 / Dataverse.

Note: I tried with Decimal but it rounded the values hence, sticking to Whole Number.

Rating Control

  1. Let’s say below is the Gallery and you want to show Ratings in the form of stars instead of traditional numeric values.

  2. Now, let’s use Rating Control below the Names of the Accounts to show the Rating values. Select the first Row once you connect to the Common Data Service i.e. CDS / Dataverse Data Source and select the entity you want to populate it with. In this example, we are using Accounts. So my Gallery is populated with Accounts records.
    Select the first record and navigate to Insert tab and look for Input controls as shown below


    Now, look for Rating control.

  3. Once you select Rating, it’ll appear iteratively since it’ll be applied “For Each” of these records in your Gallery control.


  4. I’ve just rearranged them under the name to make them look proper.

  5. Let’s make it Read Only by changing the behavior, so that the Users don’t accidently touch and set a value during Runtime. Although, this won’t affect the actual data but the representation will be incorrect in that case.

  6. Also, the Max will represent the length of your Rating whereas the Default value are kept to 0 in case the field value is not set at Source. (I think 1 would still be misrepresenting)

  7. Now, I’ll connect this Control to the Data Source’s field i.e. Rating field on the Account entity that represents the Rating value.
    On the Default, I’m setting ThisItem.Rating where ThisItem represents the Row of the Account i.e. the Account record itself and Rating is the field in Dynamics 365’s Account entity which we saw in the scenario above.


  8. And that’s it. You can Save and Publish your App and Run it.

Rating values

Now that we’ve added the Rating Control, let’s Run our App and see how it represents the data from your Accounts entity.

And the Ratings represent the below data –

There are missing dependencies. Install the following solutions before installing this one: “Active” | Connection References missing in Power Platform Solution

While importing and Unmanaged Solution into another environment, you must’ve come across these error messages like “There are missing dependencies. Install the following solutions before installing this one: “Active”

Now, there are various factors as to why this error is seen. I’ll try to cover one of them. Missing Connection References! Let’s take a look.

So, out of other reasons, one could by that there are some Flow’s Connection References that are not yet added to the Solution when it was exported out.

Error on Import

Let’s say you trying to import this Unmanaged Solution in an environment.

  1. This is your Source Solution which you want to Export and Unmanaged and Import into other environment.

  2. You see the following error on Import.

  3. Now, there are many other reasons why you are getting this error. But, in this case, it’s about missing Connection References from the Source Solution

Adding Connection Reference

In my case, it was missing adding the Connection References in the Source Solution, so here’s what I did –

  1. Go to the Add existing in your source Solution

  2. Look for Connection Reference (preview)

  3. When I add that, I can select what all Connection References are available to add.
    Here, you’ll have to select all those Connection References which you have utilized in your Solution Components.
    To understand more on Connection References, here’s a post by Alex Shlega’s posts on Connection Reference – https://www.itaintboring.com/powerapps/connection-references/

  4. When you click that, it’s added behind the scenes. Now, export the Unmanaged Solution again.



Re-Importing into Source Instance

Now, In your Source Instance, re-import this newest Unmanaged Solution.

  1. Now, importing the 1.0.0.2 version, you’ll see no issues.

  2. And when you click next, you’ll be asked to Create a Connection right away

  3. In this example, I’m supposed to create a CDS (Current Environment) connection. Because that’s what I had selected as a Connection Reference while exporting from the Source Instance.

    Skipping a few intermediate steps. My connection is created as below.

  4. Going back to the Import tab where I was importing the Solution, I’ll just refresh as directed.

  5. Any my Connection is available.

  6. I can just continue to Import as usual and it’ll be imported.

Hope this helps!

Clear a field value & Reset Form in a Canvas Power App [Quick Tip]

One of the most useful features to provide in a Form Control in a Canvas Power App is the ability to “Clear/Reset a Form” and “Clear a Field value”.

Let’s look at how Power Apps’ existing feature can help you achieve this.

Clear Field

Let’s say Description field is a lengthy field and often times, you want to clear the entire field instead of just backspacing the entire field.

  1. Let’s say Description is a DataCardValue in a typical form. Usually Descriptions are lengthy and need to be cleared if you go wrong. So, every form field value is stored in a data card value field.

  2. On the right hand properties, look for Clear Field option from the list of Text Input properties.

  3. Notice that a X appears on the field when in focus/active. So when you make a mistake in a field, click on it to clear that field.

  4. And it get’s cleared.


    This didn’t work in Multi-Line Text Box. Not sure if it’s a bug or not supported yet. I’ll confirm and update here.

Reset Form

Fairly basic way to clear out an entire form is to use a button to do so.

  1. A suitable approach is to add a ResetForm(<FormName>) function. I’ve put a sample button that denotes a reload/reset logo which I selected from Icons.


  2. Now, let’s say I want to clear this form.

  3. The form will be cleared.

Hope this quick tip helps!!

Get Dynamics 365 field metadata in a Canvas App using DataSourceInfo function | Common Data Service

Mostly, Gallery and Forms are used to work with CDS (Common Data Service) Entities data are in Dynamics 365 like Accounts, Contacts, Opportunities etc.

Some of the common field level metadata info you can retrieve is: MinValue, MaxValue, MaxLength of a field. This is dependent on whether it is supported/provided by Data Source itself, be it CDS or any other Data Source, depends.

You can leverage DataSourceInfo function to enrich your CDS form in a Canvas Power App by showing some metadata about fields. Something like below –

DataSourceInfo function

DataSourceInfo is a function that provides some info about the DataSource itself or the columns present in the Data Source.

Not necessarily all DataSources will provide all information.

In this post, I’m trying to show some metadata of the Dynamics 365 using CDS Data Source.

Microsoft’s official documentation on DataSourceInfo https://docs.microsoft.com/en-us/powerapps/maker/canvas-apps/functions/function-datasourceinfo?WT.mc_id=DX-MVP-5003911
In my example, I’ve added some labels to show these values.


MaxLength

MaxLength is used to show the maximum allowed capacity of a field. Most useful to show the maximum length of lengthy fields such as a Multi-line Text Field in Dynamics 365 CRM.

  1. Let’s say Description field in Dynamics 365 has Length provided as 600

  2. I’ve placed maxLen label below the Description field

  3. And the formula is to show the info “Max Length: <value>” is written using Concatenate() function so that I can add some text as I want to make it look more informative.

    In the above formula, in Text() function, I’ve written
    DataSourceInfo in blue. That is the formula that will take arguments like Data Source, DataSourceInfo.<Function> & Column name.
    Accounts marked by showing orange arrow is the Data Source itself since it is connected to Accounts entity in Dynamics 365.
    MaxLength is the attribute which will tell us the Maximum allowed length for the field we will enter next.
    “description” denotes the name of the column in double-quotes of which we want to know the MaxLength.

To enrich this feature, you can use this to dynamically show how much more characters are remaining in real-time as the user types into the field. Refer this post – Implement real-time search in Gallery of CDS records in a Canvas Power App | Power Platform


MinValue & MaxValue

MaxValue & MinValue are used to show the minimum & maximum value allowed in the field. Most apt is having Numeric fields in Dynamics 365 CRM.

  1. Let’s say Grading is a custom field called as Grading which is Whole Number.

  2. I’ve placed minVal and maxVal labels below Grading field in the Canvas Power App.

  3. And the formula is to show the info “Min : <value>” & “Max: <value>” is written using Concatenate() function so that I can add some text as I want to make it look more informative.

    In the above formula, in Text() function, I’ve written
    DataSourceInfo in blue. That is the formula that will take arguments like Data Source, DataSourceInfo.<Function> & Column name.
    Accounts marked by showing orange arrow is the Data Source itself since it is connected to Accounts entity in Dynamics 365.
    MinValue and MaxValue is the attribute which will tell us Minimum & Maximum allowed data values for the field user can enter  in the field in the next parameter.
    new_grading denotes the name of the column in double-quotes of which we want to know the Minimum allowed Value and Maximum allowed Value.

Hope this is useful!

Debug Published Canvas Power App with other users using Monitor | Power Platform

At times, users report that they can’t seem to know what’s wrong with their published App and the behavior is said to be unexpected. At times, no direct error is thrown to them but they don’t seem to understand what’s wrong.

Here’s what we can look at and invite them to join a Remote debugging session.

Open Monitor

In your Canvas Power App, you can find Monitor (which is in Preview as I write this post), this will open a new Monitor interface.

  1. Click on the Menu as shown

  2. Alternatively, also from the list of Apps available to you by permission.


  3. Now, when you open it, you’ll be in the Debug interface. In the interface, look for this open to Play Published App

  4. It’ll open the actual App in Play mode in the new tab.
    On the new Tab, you’ll see this message to ask you if you want to Join the session.

  5. Once you click on Join, the App will open with the message on top saying that you’ve joined the debug session.

  6. Let’s say I do a simple data entry operation by select one of the records and trying to modify it.


  7. As you then perform Actions in your App, your operations will be captured in the Monitor for you to review and debug what’s wrong.

  8. Also, if there are any specific errors that occurred, they are highlighted with Red row. You can simply click it and the details will appear on the right.

  9. Error can be investigated as below

  10. You can then investigate and see what was sent and how the payload was etc. and work towards further debugging/investigating it.

Invite Others to Debug session

Also, if you want others to simply look at what’s being captured. You can invite other users to your debugging session by clicking on Invite button

Enter their Email address and they’ll show up in the list. Copy the Link from their row and pass it on to them to join the session. They will be in read only mode and can see what’s captured and look at error details.

They can only watch and not Play the App themselves or invite others. See below

Hope this helps!!

Download a File from a Canvas Power App using a button | Power Platform

Let’s say you give a simple button to download a standard PDF file to the user. It could be a pre-defined file which already exists somewhere and your App readily has the URL to the file. You only need to provision a button to the user to download and they can simply click it and download the file to the device.

Let’s see how!

Scenario

Let’s say salespeople in your organization have access to Accounts and each Account has an exclusive Document to that Account, say, some type of Agreement/Whitepaper.

For simplicity, I’m storing the URL of the Document in a field. However, you can have a different (and better) ways to represent this. Finally, all you need is a URL to the file to be downloaded.

Download button

Here’s how I’m implementing it. To keep it simple, I’m only reading from the field on my Accounts, called as Agreement Doc URL.

Consideration: To keep this post simple, I didn’t go into the SharePoint Access settings, etc. Make sure the file is hosted over the internet and doesn’t have to go through a lot of settings to be accessible.

  1. Here’s my Gallery that shows all the Accounts.

  2. When I make a selected to any of the records, it’ll open the Form and pre-populate the form with the selected record. However, your application could be anything.
  3. I’ll place a button on click of which, I’ll write the Function to download a file.

  4. And the function used it Download()

    In my example, I’m choosing to download the file which is supposedly coming from my AccountView (which is a Gallery). Selected method is pointing to the row from my CDS Data Source which I selected in the Gallery and navigated to the Formevery of my Account records have their own respective URLs and Agreement Doc URL is the name of the field in which the URL to the document resides.

    Here’s Microsoft Document on this function – https://docs.microsoft.com/en-us/powerapps/maker/canvas-apps/functions/function-download/?WT.mc_id=DX-MVP-5003911

AddColumns() function to dynamically add columns to a Data table in Canvas Power App | SharePoint List

At times, you want to do a quick calculation but the Data Source doesn’t have that column present.

Example, you’re populating some data from a SharePoint List which is a Scoreboard. But it doesn’t tell the difference between the current Score and Top Score.

So, to find how many points does the Score trails by the Top Score. To do that, we’ll dynamically add a Column to our Data Table in a Canvas Power App by using AddColumn() function.

SharePoint List & Canvas App

First part is the list itself which you already saw above, I have the below Canvas App –

  1. The only thing I have in this Canvas App is a Data table which I named as ScoreBoard

    Which will look like this

  2. I’m setting the Data Source of this Data Table to be DynamicList and not the actual SharePoint List. Because, in order to create a dynamic column, I should be using Collections in this demo and I can’t use the SharePoint List as Data Source directly.

  3. And to write my function, I’ll also add a Button so that on click of which, I can populate my internal Data Source in this case which is Collection called as DynamicList to be populated with data. You can use any other way as suitable.

AddColumns() function

  1. Since I want to generate my dynamic column, I’ll first use ClearCollect() method to add the SharePoint List with the dynamic column to my Collection which I’ll call as DynamicList.
    All this OnSelect of the Button which I added.

  2. The formula goes as below
    ClearCollect(<NameOfCollection>, AddColumns(<ActualDataSource>,”ColumnName”,<Expression>))

    In the above formula,
    ClearCollect(DynamicList) is being created to create a Collection called DynamicList and Clear if there’s any pre-existing data in it before populating fresh data.
    AddColumns(Scoreboard,”Trial By”, ‘Top Score’ – Score) – Scoreboard is the actual SharePoint List I’m using which doesn’t have the column, Trial By is the dynamic column I’m creating. And my expression is Subtract Score from Top Score so that I get the difference.

  3. Make sure you select the columns. Perhaps once you run in in your browser, and try to click the button, the column will be available for your selection in the below Edit Fields section. [I had to do a little back and forth, perhaps you might have a smarter way 😊]



    Here’s Microsoft Docs on the function – https://docs.microsoft.com/en-us/powerapps/maker/canvas-apps/functions/function-table-shaping ?WT.mc_id=DX-MVP-5003911

Run

Now, when I run the app, and click on Load Scoreboard button, I see the below data populated with by dynamic column Trail By.


Hope this was useful.
