I have one button and one combox, the button is greyed out by default, and when user selects something from the dropdown list, the button should be available, however the below function didn't work as expected, please advise. Thanks

If(IsBlank(RecordingAccess.SelectedItems.DisplayName),Button1.DisplayMode.Disabled,Button1.DisplayMode.Edit)

Hi @sdnd2000 ,

If you put this on the DisplayMode of the Combo Box, it should work.

If( IsBlank(RecordingAccess.Selected.DisplayName), DisplayMode.Disabled, DisplayMode.Edit )

Hi, @eka24
It works, but why do I have to set the button display mode for this case ? I thought it is enough to set the combox ?

I understood your request is to change the display mode of the button based on the Combobox.

If that is not the case let me know. What are you disabling? Button or Combobox?

If the button, then the formula I gave is ok as you have confirmed

Hi, @eka24
yes, your formula is fine.
My question is why I can not put the formula in the onChange event of the combox?

I answered in the previous reply that it depends on what you want to disable. In your case you want to disable or enable the button, so it should be placed on the displaymode of the button and not the Combobox. I hope it clear.
