send a default value when a drop-down list field is empty

(0) ShareShare

Posted on by Community Power Pla... Microsoft Employee

Hello,

 

So here we are, in my SharePoint list, I have a list of choices (of 2 values) with one of the two choices as the default value.
In powerapps, I have a drop-down box for these two choices. My problem is that when the control is empty (so no sectioned choices), I would like the value returned to SharePoint to be the default value set in my SharePoint list, so one of my choices.

 

Thank you in advance for your help

    There's a few ways of doing this. The clearest and easiest way would be to set the dropdown list to automatically display the default choice. It avoids needing to put in an experience to catch a blank response.

     

    If the dropdown is in a Form control, I prefer to change the Default property of the card instead of the dropdown control itself. This way the dropdown can easily inherit Parent.Default.

     

    1. You can use the Choices function to get a table of options for that column.
    2. Then in the Card's Default proprety, you can filter the table of options to the record you want:
      LookUp(Choices(datasource.column_name),Value="your option here")
      This looks up the first choice of the choices available for that column which matches your given Value.

     

    Let me know how this goes.

    thank you for your answer @Mr-Dang-MSFT ,

     

    Indeed, that's what I was looking for, it's working now.
    Before you answered I couldn't compare the values (with the Value="your option here" part) but it's done.

     

    Thank you again
