Posted on by jd38

Hi all,

Is there a way or a simple method to get all fields where the property "Required" is set to true ?

Before the save of my form, i would like to show the list of required fields that are empty and show it in a pop-up.

I have around 100 fields in my form.

Many thanks

The easily wait to achieve that, i would recommend to create a Power Automate flow that will retrieve metadata from the table and then get the list of required fields.

Here is an example: /api/data/v9.2/EntityDefinitions(LogicalName='account')?$select=LogicalName&$expand=Attributes($select=LogicalName,RequiredLevel)

you will be able to get this information

and return the list of fields that are required to your canvas app

Hi jd38,

I have a solution but I am not sure if its the best one given you have 100 fields, which I personally think is a lot for any form. Here's what I have created -

OnSelect of Save Button

Clear(missingfields); If(IsBlank(DataCardValue5.Value),Collect(missingfields,title_DataCard1.DisplayName), false ); If(IsBlank(DataCardValue6.Selected),Collect(missingfields,Person_DataCard1.DisplayName), false ); If(IsBlank(DataCardValue7.Selected),Collect(missingfields,'card lookup_DataCard1'.DisplayName), false ); If(IsBlank(DataCardValue8.Selected),Collect(missingfields,Test_DataCard1.DisplayName), false ); If(IsBlank(DataCardValue18.SelectedDate),Collect(missingfields,DOB_DataCard1.DisplayName), false ); If(IsBlank(DataCardValue26.Value),Collect(missingfields,Description_DataCard1.DisplayName), false ); Set(showMissingFields, true )

Visible property of the above elements -
ShowMissingFields

OnSelect of Okay Button

Set(showMissingFields, false)

Hope this helps.

Kind regards,

Nandit
