Questionhow to reject the invalid row adding to datatable? Pin
wangier8-Jan-04 16:39
Memberwangier8-Jan-04 16:39 
dataTable1.RowChaging += new DataRowChangeEventHandler(dataTable1_rowChaing)

private void dataTable1_RowChanging(object sender, DataRowChangeEventArgs e)
{
if ( e.Action == DataRowAction.Add )
{
if (...)
throw new ApplicationException("不合法的检查项目!");
}
}


------------
the problem is :
this dataTable is associated to a datagrid, when add a new row through the datagrid, the rowchanging event can be trigered. If the row is invalid, the exception will be throwed, and the new row cannot be added to the dataTable1.
But when should I handle this Exception? I can't catch this exception.
