Question Deleted row bindingsource error ?

[ebrahim]

Hi friends.
I once sent a table to store the database.
To add no problem.
But when I clear the table a few lines or 1 line gives the following error message

:

Deleted row information can not be accessed through the row.

UI Layer :

try
            {
                blCls._Kind = 3;
                gridViewCarName.FocusedRowHandle = 0;
                bsCarName.DataSource = gridControlCarName.DataSource;
                blCls._CarList = bsCarName.DataSource as DataTable;
                str = blCls.dalAddList();
                if (str != "1")
                {
                    ShowMessage.Show(str, "خطا", ShowMessage.PersionMessageBoxButton.Ok,ShowMessage.PersionMessageBoxIcon.Error);
                    return;
                }
            }
            catch (Exception ex)
            {
                ShowMessage.Show(ex.Message, "خطا", ShowMessage.PersionMessageBoxButton.Ok, ShowMessage.PersionMessageBoxIcon.Error);
                return;
            }
