Hi guys

I've got a List of items for editing a Contact. Basically, it's a list of
groups - a contact can be a member of as many as possible, or a member of one.

Is there a way to make asp:ListBox allow none to be selected!?

Failing that, any free controls that will do it?

Cheers

You could make the first selection item "Select None" and in the changed
event

Private Sub ListBox1_SelectedIndexChanged(ByVal sender As System.Object,
ByVal e As System.EventArgs) Handles ListBox1.SelectedIndexChanged

If ListBox1.SelectedIndex = 0 Then

ListBox1.SelectedIndex = -1

End If

End Sub
