I have a Method to filter a ListBox by removing Rows that don’t contain certain text. It works fine for Desktop. It also works fine for Web in a Test app. But the same Method is giving a KeyNotFoundException in my Web App when it goes to .RemoveRowAt(XXX) where XXX is an existing Row (ie not out of bounds).
In my case it is wanting to remove Row #2 and there are 8 Rows in the WebListBox.
I created a test WebApp and the same Method has no KeyNotFoundException. Any clues on why this might be happening?
