GDBG - Hierarchical grid shows + when no children present

Question

Is there an event that I can handle to make the display of this column accurate?  I tried the CellDrawn code in one of the samples posted here (see below) but it must be firing constantly as I can barely even get my context menu to display.

-------------------------------------------------
if (e.ColIndex == 1)
{
	GridBoundRecordState state = this.Binder.GetRecordStateAtRowIndex(e.RowIndex);
	if (state.HasChildList && state.ChildCount == 0)
	{
		bool boolIsExpanded = this.IsExpandedAtRowIndex(e.RowIndex);
		this.BeginUpdate();
		this.Model.SuspendChangeEvents();
		this.ExpandAtRowIndex(e.RowIndex);
		this.CollapseAtRowIndex(e.RowIndex);
		this.Model.ResumeChangeEvents();
		this.EndUpdate();
		this.Invalidate(e.Bounds);
	}
}

Hi Lori,

I think you are using 3.3, this bug is fixed in 4.1.

Defect #872 - All rows display a plus or minus regardless of their state( i.e. no children)
 
v4.1 final release is available for download. Please refer to the following link for more information in this regard :
