Gridgroupingcontrol child table values from grandchild table

In the QueryCellStyleInfo event of a gridgroupingcontrol, I need to disable/enable certain cells in a grandchild level (3rd level) table based on the ChildTable parent value (2nd level). i.e., from the grandchild level, I need to pull info from the CHILD level table (not the top-most level parent). How would you retrieve the childtable parent record information from a grandchild level table (in VB.net)? Thanks, Robert

Here is one way you can get at the child table from within the grandchild table.
private void gridGroupingControl1_QueryCellStyleInfo(object sender, GridTableCellStyleInfoEventArgs e)
	GridTable table = this.gridGroupingControl1.GetTable("GrandChildTable");
	if(table != null && table.Equals(e.TableCellIdentity.Table) 
		&& e.TableCellIdentity.DisplayElement is GridRecordRow
		&& e.TableCellIdentity.DisplayElement.Kind != DisplayElementKind.AddNewRecord
		GridRecord rec = e.TableCellIdentity.DisplayElement.ParentChildTable.ParentNestedTable.ParentRecord as GridRecord;
		DataRowView drv = rec.GetData() as DataRowView;
		Console.WriteLine(drv["Name"].ToString() + "  " + drv["childID"].ToString()); //some values
