Set your DropDownList to AutoPostback... then you can check on the server if the value they've selected is invalid.

I'm not clear on what the problem is, could you please elaborate on what your program is supposed to do?

Please post your code for populating (adding items to) your DropDownList.
I'm not sure if you're trying to programatically set the selected value, or if you are talking about letting the user select a value.

Are you trying to remember the value that the user selected?
Then after adding new values, resetting the selected value?

I still don't understand what you are trying to do.

To set the selected item programatically :
[code=vbnet]
'If you only know the value that should be selected:
myDropDownList. Items.FindByVal ue("the value that should be selected").Sele cted = True
'If you know the index that should be selected:
myDropDownList. Items(0).Select ed = True
'....
[/code]

You should probably also post the code for your AutoPostBack event (the Selected Index Changed event)
