Here is a thread on the Ctl+A. http://www.syncfusion.com/Support/Forums/message.aspx?MessageID=30516 On the drag and drop question, where do you want your user to drop the rows? Would it be more intuitive to have a "Toggle Selections" context menu item than to try to flip selections using drag & drop. If you want to use drag and drop, you will have to catch the DragDrop event on the target object (that is why I asked where you wanted to drop the rows). At that point, you would iterate through the records changing the values.

You can try this code.
private void gridGroupingControl1_SelectedRecordsChanged(object sender, SelectedRecordsChangedEventArgs e)
	if(e.SelectedRecord != null)
		lastRecord = e.SelectedRecord.Record;
		lastValue = e.SelectedRecord.Record.GetValue("boolCol");
		if(lastValue == null || lastValue.ToString().Length == 0)
			e.SelectedRecord.Record.SetValue("boolCol", true);
			e.SelectedRecord.Record.SetValue("boolCol", !(bool)lastValue);

Try setting alpha channel of the selection color to zero: this.gridControl1.AlphaBlendSelectionColor = Color.FromArgb(0, Color.Red);

I think what you want is not to select records, but to select cells. Here is your sample modified to do this. You can select a range of ckecboxes, and then clcik the check to set all the selected checkboxes with one click. http://www.syncfusion.com/Support/user/uploads/GGC_SelectCheckBox_ecdfd005.zip

I do not know what painting problem you are talking about. Can you upload a screen shot showing the painting problem? The only thing I see that is odd is if you click any cell in the row, the checkbox changes. The reason the checkbox changes when you click a cell is that you are selecting rows. And you have code that says when a row gets selected to flip its bool value. So the value gets flipped. The only solution I know to this problme is not to select rows, but to select cells. And that is what the sample I sent you does.
