Hello , I have downloaded the jqGrid for ASP.NET .

While I was trying to create a Hierarchy scenario (Sub Grid (2 nestes levels)) , I attempted to do it as the demo says and tried to add the (HierarchySettings) property for the grids.This however is not working for me as the project wont compile and the error is the following

(Type 'Trirand.Web.UI.WebControls.JQGrid' does not have a property named 'HierarchySettings').
