    Bill,

    I stepped through both the add button click handler and the update button click handler. Both took me on a long trip through the application, starting with sub Main. In the end I didn't get any information. All's that happened is that when I clicked Add, put in a new publication but left the comboboxes alone, and then clicked update, the row appeared in the datagrid with nulls in the columns with comboboxes.

    when I use Debug.Assert(cboPubFreq = DBNull), I'm told dbnull is a type and cannot be used in an expression. It doesn't like null or system.dbnull, either.

    sob.

    BTW, what does eMVP stand for? Extra? Extraordinary? EventArgumentsMVP?
