vb.net web form pass value to combo validation question

Hi
I have a web form, using vb.net code behind, with a combo box populated with
a dataset (Name, ID). What I have found, unlike a windows form, is that if
you try to pass a value (ID) into the combo and that value is not part of the
dataset, the web form blows up.
If (Context.Items("ID") <> "") Then
cboEmployeeID.SelectedValue = Context.Items("ID")
End If
Testing for empty string does help some but there are times when we have bad
data and the ID value will not match any in the dataset.

Is there a way to trap this so my form does not error out?

Thanks
Brian
