Are you using the record selection support in GridGroupingControl (and not teh selection support inherited from GridControlbase)?

//GridGroupingControl record selections
this.gridGroupingControl1.TableOptions.AllowSelection = GridSelectionFlags.None;
this.gridGroupingControl1.TableOptions.ListBoxSelectionMode = SelectionMode.MultiExtended;

If so, you can handle the TableControlCellClick event and select the records there.

private void gridGroupingControl1_TableControlCellClick(object sender, GridTableControlCellClickEventArgs e)
{
	GridTableCellStyleInfo style = e.TableControl.Model[e.Inner.RowIndex, e.Inner.ColIndex];
	if(style.TableCellIdentity.TableCellType == GridTableCellType.TopLeftHeaderCell)
	{
		this.gridGroupingControl1.BeginUpdate();
		foreach(GridRecord rec in gridGroupingControl1.Table.Records)
		{
			if(!rec.IsSelected())
				rec.SetSelected(true);
		}
		this.gridGroupingControl1.EndUpdate(true);
	}
}

You can handle the TablControlCurrentCellControlKeyMessage event.

private void gridGroupingControl1_TableControlCurrentCellControlKeyMessage(object sender, GridTableControlCurrentCellControlKeyMessageEventArgs e)
{
	Keys keyCode = (Keys) ((int)e.Inner.Msg.WParam) & Keys.KeyCode;
	if(keyCode == Keys.A && e.Inner.Msg.Msg == 0x100 //WM_KEYDOWN
		&& 0 != (Control.ModifierKeys & Keys.Control))
	{
		//ctl+A pressed
		this.gridGroupingControl1.BeginUpdate();
		foreach(GridRecord rec in gridGroupingControl1.Table.Records)
		{
			if(!rec.IsSelected())
				rec.SetSelected(true);
		}
		this.gridGroupingControl1.EndUpdate(true);
		e.Inner.Handled = true;
		e.Inner.Result = true;
	}
}

HI,

If there are few thousands of records, then this was of selecting all the records is taking lot of time and this is really a performance issue.

I am wondering is there any single method like SelectAllRecords()/AddAllRecords to the SelectedRecords collection? (as we have GGC.Table.SelectedRecords.Clear() )..

Plz inform me.
