All nodes inside a RadTreeView showing on first level

[exp]

 

I am trying to populate tree view data but all the nodes get displayed at same root level. Tree view is not showing me the hierarchy. I have attached screenshots as well for aspx , data and ui being displayed for me. Please help me find out what am i doing wrong. I am using telerik ui for asp.net webforms.

Got it resolved ! My bad ! i was doing the binding to datasource first then defining the parent child relations instead of this: 

treeView.DataTextField = "Text";
            treeView.DataFieldID = "ID";
            treeView.DataFieldParentID = "ParentID";
            treeView.DataSource = siteData;
            treeView.DataBind();
