Cannot Expand/Collapse/Check/Uncheck RadTreeView and Expand/Collapse RadPanelBar

[phyrom]

Dear Supporter,

I'm using the RadTreeView inside the RadPanelBar to build webpart for SharePoint 2010.

Everything works fine except that users cannot expand/collapse or check/uncheck the tree view. I have enable the CheckBox for treeview.
It just doesn't happen to RadTreeView control only but also RadPanelBar which I cannot expand or collapse the bar item.
Please note that both Telerik.Web.UI and Telerik.Web.Design files are deployed to GAC.
After googling and search through some existing deploying the RadControl to SharePoint or IIS, I have summarized and get those to update in the Web.Config as following; however, there is still no luck.

Please advise which how to make the control to be expanded/collapsed or checked/unchecked based on user Mouse interaction.
