Are you pretty sure that in those code the exception is being raised?, I can't see any assignment to your ite2_ddl control
ASKER
Many thanks all.
Jorge,
here is the part I can see in the whole project, that is having an assignment to ite2_ddl.

if (reader["ite2_id"] != null)
{
if (reader["ite2_id"] != DBNull.Value)
{
ite2_ddl.ClearSelection();
ite2_ddl.SelectedValue = Convert.ToString(reader["ite2_id"]);
}
}
I think that ite2_ddl doen't have ite2_id in its values
ASKER
No, ite2_id is the column which is from another transaction table.
