Object Data Source Computed Column

[Guest]

I have a list box that is bound to an object data source. I added a column,
say ColumnC, to my typed data set and for it's expression I entered

ColumnA + ': ' + ColumnB

When I preview the data in the designer I get exactly what I want.

Now I go over to the object data source on my web page, refresh it and
refresh the schema. I can now see ColumnC as an option for the list box's
data text field. However, when I run the page nothing shows up in the list
box. However, when I view the page source, I see that the data value field
did render

Does anyone know what I missed?

Thanks

Gotta be a problem the way the listbox is rendering. Can you post the
HTML?
