I think you actually want to use .text value. Actually you can databind the
same combobox to 2 different datasources. So if you have a table that has
the query name, query you could do something like this
cbo.datasource=table
cbo.diplaymember=column0name
cbo.databinding.add(new binding("text",table,"column0name)
cbo.databinding.add(new binding("valuemember",table,"column1name)
then you would be able to get the querystring off the .selectedvalue
property.
Play around with it some, I ALWAYS have to tinker with my comboboxes because
it always seems each situation needs a different approach. Combos are a
pain...but thats because they are very powerful.

As a matter of fact, is it possible to get the text associated with an
index within the combobox without actually modifying the .selectedindex
property? It is extremely annoying, trying to change within the program
code the selected index, only to have it crash because... I don't even
know why. I can't understand why it won't allow me to change the selected
index! The tooltip in VB.NET tells me that the .selectedindex method
allows me to get or set the index that is selected. Maybe if someone can
point me to a detailed explanation of this idiotic behavior and how to
work around it? I just want the invisible combobox's index to be the same
as the visible one. My AIM name is ajeric74... SOMEBODY please come online
to help me!!!

news:vM*****************@newssvr14.news.prodigy.co m... Okay, I have another question: What I'm trying to do is to use an
ordinary combobox to hold the query title, and an invisible combobox to
hold the actual query. I want to make it so that the invisible combobox
will change to match the visible one, thereby allowing its .text property
to contain the proper query. Is that possible?
TIA,
Eric

If not me.cmbComboBox.selectedindex=-1 then
'do something
end if
put that inside your handler....

Me.cmbComboBox= New System.Windows.Forms.ComboBox()
Then cmbComboBox.SelectedIndex is -1 (default value)
You get an error if you would try this:
Me.cmbComboBox= New System.Windows.Forms.ComboBox()
cmbComboBox.SelectedIndex = 0
Can't you exit event _SelectedIndexChanged when the index is invalid?
With cmbComboBox
If .SelectedIndex < 0 Or .SelectedIndex >= .Items.Count Then
Exit Sub
End If
End With
