I want to add an "All" option to the combo box. When user selects the option "All", then automatically selected all options.

If user deselects the option "All", then deselect all options. But how can I get which combo box option is being deleted?

Hi @WilliamSu,

Could you please share a bit more about your scenario?

Do you want to find out which Combo Box is empty?

Assume that you have multiple Combo Boxes and you deselect the "All" option from one of them, and you want to make some notification to remind yourself, right?

I think you could use the OnChange property of the Combo Box, set the OnChange as below:

If(IsEmpty(ComboBox11.Selected)||IsBlank(ComboBox11.Selected),Notify("Here deselects all the options!",Error))
