I have 2 drop down boxes. When a selection is made from the first one then the second is populated based on the selection. If the selection is changed in the first drop down then the second list has the items for the new selection but also retains the items from previous selections.
I want all the items in DDL2 to be wiped and replaced with the new items not appended.
Did that make sense?
I have tried using
Protected Sub DDGroups_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles DDGroups.SelectedIndexChanged
But no good
