Actually, this issue applies to any control that uses ListItem, not just dropdowns. And it’s not that uncommon for me since my client requires us to use “Yes” and “No” dropdowns instead of checkboxes so I might have 3 or more dropdowns with the same items in the same page. Another workaround is to populate your dropdowns like this (sorry, it’s VB):

Public Sub PopulateDropDowns2(ByVal sender As DropDownList)
Dim lo As ListItem
lo = New ListItem(”Select”, -1)
sender.Items.Add(lo)
lo = New ListItem(”No”, 0)
sender.Items.Add(lo)
lo = New ListItem(”Yes”, 1)
sender.Items.Add(lo)
End Sub

My 5 cents, I started to get the same error when I migrated to .net 2.0 and 3.5, my code is quite complicated but works for sure with .net 1.1. I tried this solution and still get the same error on .net 2.0 and VS2008, downgraded back to 1.1, compiled with VS2003 and works fine without code modifications
