I need extended information for an existing table. So I created another table and in the DataGridView_Prerender event I write code to create new records in the new table to tie to the existing table.
This worked fine until I needed to use a checkbox in the DataGridView. Because the record set is empty at the time the <ItemTemplate> tag for the checkbox is being initialized; I get an InvalidCastException error within the <ItemTemplate> tag.
Anyone know what I need to do to get around this error?
