Hi Nitin,

Could you please confirm that you are not using simple binding with DataBind() calls to populate your hierarchy grid?

Note that hierarchical structure is not supported with Simple data binding. For advanced features like hierarchy presentation the RadGrid control requires advanced data-binding through its NeedDataSource event or a data source control.

   GridViewTemplate childTmpt = new GridViewTemplate();
            try
            {
                rgdView.BeginEdit();
                rgdView.GridElement.BeginUpdate();
                rgdView.MasterGridViewTemplate.ChildGridViewTemplates.Clear();
                rgdView.Relations.Clear();
                using (DataSet dsTmp = test.loadChild())
                {
                    childTmpt.DataSource = dsTmp.Tables[0];
                    childTmpt.AllowAddNewRow = false;
                    childTmpt.AllowEditRow = false;
                    //childTmpt.AutoSizeColumnsMode = GridViewAutoSizeColumnsMode.None;
                    childTmpt.AllowColumnResize = true;
                    rgdView.MasterGridViewTemplate.ChildGridViewTemplates.Add(childTmpt);

Hi Nitin,

Could you please confirm that you are using the RadGrid control for ASP.NET AJAX in your application?
