delete multiple lines in DataGrid, message always shown deleting the first line

[Ryan Liu]

private void dt_RowDeleted(object sender, DataRowChangeEventArgs e)
{
int id= (int)e.Row["id", DataRowVersion.Original];

if(id >5)
{
e.Row.RejectChanges();
MessageBox.Show(this, "Can not delete!" + id);
}

}
When multile lines are selected and deleted from the datagrid by using
delete key.

The warning message showned by MessageBox.Show() always same. id never
changed, always the firt one.

Is this a known bug, any work around?

Thanks a lot!

It seems that you might be able to pipe in the selected rows into an array first.

You would then of course have to modifiy the output of the message box to
show all the selected id's that cannot be deleted.

private void dt_RowDeleted() will be triggered multiple times, once per row.

I Suppose each time triggered on different row, but seems to me, always on
the same row.

So I think it is not about modify output of the message box.

Thanks,
