Hello Fred,
To make the DataGrid a coincident behavior no matter where the focus is at,
you need to handler all KeyDown events of the child controls inside the
DataGrid. To do this, you may handle the ControlAdded event of the
DataGrid. for all controls added to the DataGrid, add your KeyDown event
handler to the control's KeyDown event
For more detailed information about the ControlAdded event please see:
http://msdn.microsoft.com/library/en-
us/cpref/html/frlrfSystemWindowsFormsControlClassControlAddedTopic.asp
This is a sample code of handling DoubleClick event of the whole DataGrid.:
private void InitializeComponent()
{
this.dataGrid1.DoubleClick += new
System.EventHandler(this.dataGrid1_DoubleClick);
this.dataGrid1.ControlAdded += new
ControlEventHandler(this.dataGrid1_ControlAdded);
}
private void dataGrid1_DoubleClick(object sender, System.EventArgs e)
{
MessageBox.Show("dataGrid1_DoubleClick");
}
private void dataGrid1_ControlAdded(object sender, ControlEventArgs e)
{
e.Control.DoubleClick += new
System.EventHandler(this.dataGrid1_DoubleClick);
}
I hope this helps you.

| Hello Lion,
| Sorry, it isn't a problem in the IsSelected method as I
| thought before. It's just, that if the grid has the focus
| and I press return to trigger the default button's click
| event, the selection in the grid is cleared before the
| default button action is entered.
| If I click the button with the mouse, the selection
| beheaviour is correct. Can I handle the return key
| somehow before the grid clears its selection. The KeyDown
| event is apparently not fired for the return key
| Best regards
| Fred
