I have a Hierarchical Grid where the child rows have a check boxes enabled for row selection 

This behavior can be seen on the Row Selector Checkboxes example  http://es.infragistics.com/products/jquery/sample/hierarchical-grid/row-selector-checkboxes

If I click on several of the check boxes, the check box is checked and the rows take on a selected color.  If I then click on a parent row the check box state is maintained which is what I want.

Now if I CTRL click on the same rows visually it appears the same [the check box is checked and the rows take on a selected color.]  However if I click on a parent row all of the items immediately become unselected/unchecked which is what I do not want.

Is there a way to have click/selecting a cell but not selecting it via the check box to keep the check box selected.  I look for a way to hook into an event and manually set the checkbox status like it was clicked on but could not locate anything to do this.
