I have couple of DDL's, namely DDL1 and DDL2. The latter is dependent on the DDL1, which is creating some problem for me. When I choose a value in DDL1 it populates DDL2 accordingly but when I choose a different value in DDL1 it still shows the result from my previous selection in DDL2.
How do I remove historical values from DDL2 and only shows values matching to what is selected in DDL1.

View 3 RepliesI have been trying to figure out how to Clear out the contents of a combobox; both the dropdown list and the textbox. Currently I have
combobox1.Items.Clear()
combobox1.ClearSelection()
this is clearing out the listbox, but if something was in the Textbox it remains. If I add
Combobox.Text=""
then I get "Combobox has a SelectedValue which is invalid because it does not exist in the list of items."
I've tried several other combinations, none of which worked. how to clear out textbox portion of the combobox?
