I have bound listbox as below.
lstWrap.ValueMember = "ItemCode" 'As it is a number field, I tried tostring
also
lstWrap.DisplayMember = "Description"
I get the following err at run time
System.ArgumentException: Could not bind to the new display member.
I can't see anything wrong in the code. Any hlp/suggestions?

You have to set the DataSource to the DataTable or DataView. Listboxes
can bind to any collection of objects, and ValueMemeber does not have to
be a string...

Hi Brian,
I've already bound the datasource to a dataview.
when I say
lstWrap.ValueMember =3D "Description"
then it works but this will not bind the itemcode to the listbox. My
requirement is a typical listbox of look up vals frm a database.
I even checked on some saple codeon the internet. I had the same code as
in
the sample. But stiill mine doesn't work. Any suggestions?
Regards,
S.Malathi
