Posted on by Community Power Pla... Microsoft Employee

On unchecking a checkbox in a gallery (which is inside a form), i need to reset a combobox (SharePoint single choice field) to a blank value. I have set the RESET property of the combobox to TRUE and added the below code while unchecking the checkbox :

Set(ResetDataCardValue1,true);Set(myDataCardValue1, {Value: Blank()});

And i have set the DEFAULTSELECTEDITEMS to If(ResetDataCardValue1,{Value: myDataCardValue1}, Parent.Default). its not working.

I also tried If(ResetDataCardValue1,{Value: ""}, Parent.Default), If(ResetDataCardValue1,{Value: [""]}, Parent.Default) still not working.

Please suggest solution

Hi @Anonymous ,

The OnUncheck of the Checkbox

Set(ResetDataCardValue1,false), Set(ResetDataCardValue1,true)

Make the Reset of your Combo Box

If( ResetDataCardValue1, {Value: Blank()}, {Value:ThisItem.YourFieldName} )

Thanks for your reply but before i saw your message, i went with a different solution approach (by replacing the choice column with a single line of text.) so on and so forth.
