First fire of 'SelectedIndexChanged' event works, but not on 2nd fire

[DotNetter]

I have this line in my SelectedIndexChanged event:[tt]
Dim SelectedClassID As Integer = CType(lvwRequestSummary.SelectedItems(0).Tag, Integer)[/tt]

The tag is set to a valid integer. That does not seem to be the problem.

On the first fire of this event, this line works and the variable is properly assigned to an integer. On the second fire of the event, it blows up and tells me that the "0" in the index of "lvwRequestSummary.SelectedItems(0)" is "out of the range of valid values. Parameter name: index"

How could this be?

Thanks!

can you use this in that event and see what happens


Dim iTest As Integer=-1
iTest=lvwRequestSummary.SelectedItems.Count
If iTest > 0 Then
Dim SelectedClassID As Integer = CType(lvwRequestSummary.SelectedItems(0).Tag, Integer)
End If
