您必须实现如下所示的 SQL DataTable 事件处理程序:

YourDataTable.RowDeleted += new DataRowChangeEventHandler(dataTable_RowChanged);

    private void dataTable_RowChanged(object sender, DataRowChangeEventArgs e)
    {
        DataRow _dr = e.Row as DataRow;
        try
        {
            if (e.Row.RowState == DataRowState.Deleted)
            {
              // YOUR CODE
            }
            if (e.Row.RowState == DataRowState.Added) { //OPTIONAL }
            if (e.Row.RowState == DataRowState.Modified) { //OPTIONAL}
        }
        catch (Exception ex) { }
        finally { _dr = null; }
    }

希望这对您有所帮助。最好的问候，
