Is there a way I can determine when the vertical scrollbar of the grouping grid is shown/hidden? I want to use this in a resize-to-fit feature. For example, if the user expands a group or adds a row, this may lead to the vertical scrollbar being shown. I want to detect this situation in order to resize the grid columns.

Try checking this.gridGroupingControl2.TableControl.VScroll.

I probably explained my problem poorly. I don''t want to disable or enable the scroll bar. I am looking for an event that I can hook into to be notified when the grid decides to show or remove the vertical scrollbar.

Try handling the this.gridGroupingControl2.TableControl.SizeChanged event. There you can use the above property to tell when the VScrollBars comes and goes.
private bool oldVScroll = false; 
private void TableControl_SizeChanged(object sender, EventArgs e)
	if(oldVScroll != this.gridGroupingControl2.TableControl.VScroll)
		Console.WriteLine("vscrollbar: {0}", this.gridGroupingControl2.TableControl.VScroll); 
	oldVScroll = this.gridGroupingControl2.TableControl.VScroll;

That did the trick. Thanks a lot, Clay.
