Behavior of the DataGrid while closing the application

[schaf]

Hi NG!
I have recognized a strange behavior of the DataGrid control.
If I'm editing the value of a cell in the DataGrid and press the
close
button (of the ControlBox of the application 'X') then the
application
closes but the DataGrid does not loose the Focus. I would like to
save
the changes done in the corresponding cell.

How can I check if I have to save the value in the data grid?


regards
Marcel

Can you switch to DataGridView? This appears to be fixed, as
demonstrable by adding the following to my last post:

(add the bottom of the ctor)
DataGridView dg = new DataGridView();
dg.Dock = DockStyle.Fill;
dg.DataSource = new SomeData[] { data };
Controls.Add(dg);
dg.BringToFront();

(add to the class)
protected override void OnClosing(CancelEventArgs e) {
e.Cancel = MessageBox.Show(this, data.Name + " : " +
data.Size, "Closing", MessageBoxButtons.OKCancel,
MessageBoxIcon.Question, MessageBoxDefaultButton.Button1) ==
DialogResult.Cancel;
}

With DataGridView you see the new values in the message-box,
suggesting that updates and validation have occurred; with DataGrid
you get (as you posted) the old values.

Can you switch to DataGridView?
No because I'm working on .NEt 1.1
But I have obtained help from the net and the easiest way to solve the
problem is to change the focus of the control in the Closing event.

Thanks
