I set the mastertableview header in ItemDataBound for both Master and Detail TableView.  But when I click to expand the details, the mastertableview header changed back to the field name.   And when I click the other expand button, the first details header also changed to fieldname.  Where should I put the headertext code in my code behind?  I am using vb.net.
Tks,
                                Tks,
