I use VS 2005 with framework 2.0, I have a webhierarchicaldatagrid, i bind data programmatically with it by using following code,

 Dim dvParent As Infragistics.Web.UI.DataSourceControls.DataView
            Dim dvChild As Infragistics.Web.UI.DataSourceControls.DataView
            Dim tOrders As DataTable = New DataTable("Orders")
            Dim tOrder_details As DataTable = New DataTable("Order_details")
            tOrders.Columns.Add("Name", GetType(String))
            tOrders.Columns.Add("StartDate", GetType(Date))
            tOrders.Columns.Add("EndDate", GetType(Date))
            tOrders.Columns.Add("ClassID", GetType(String))
            tOrders.Columns.Add("ID", GetType(String))

            tOrder_details.Columns.Add("Name", GetType(String))
            tOrder_details.Columns.Add("StartDate", GetType(Date))
            tOrder_details.Columns.Add("EndDate", GetType(Date))
            tOrder_details.Columns.Add("ClassID", GetType(String))
            tOrder_details.Columns.Add("ID", GetType(String))

            For Each eRow As DataRow In CurrentEnrollments.DS.Tables("ClassEnrollment").Rows
                Dim tmpRow As DataRow
                tmpRow = tOrders.NewRow()
                tmpRow.Item("Name") = eRow.Item("Name")
                tmpRow.Item("StartDate") = eRow.Item("StartDate")
                tmpRow.Item("EndDate") = eRow.Item("EndDate")
                tmpRow.Item("ClassID") = eRow.Item("ClassID")
                tmpRow.Item("Id") = eRow.Item("ID")
                tOrders.Rows.Add(tmpRow)
            Next


            For Each eRow As DataRow In CurrentEnrollments.DS.Tables("LEIEnrollment").Rows
                Dim tmpRow As DataRow
                tmpRow = tOrder_details.NewRow()
                tmpRow.Item("Name") = eRow.Item("Name")
                tmpRow.Item("StartDate") = eRow.Item("StartDate")
                tmpRow.Item("EndDate") = eRow.Item("EndDate")
                tmpRow.Item("ClassID") = eRow.Item("ClassID")
                tmpRow.Item("Id") = eRow.Item("ID")
                tOrder_details.Rows.Add(tmpRow)
            Next

            'tOrders = CurrentEnrollments.DS.Tables("ClassEnrollment")
            'tOrder_details = CurrentEnrollments.DS.Tables("LEIEnrollment")
            Dim hdsMain As New Infragistics.Web.UI.DataSourceControls.WebHierarchicalDataSource()
            dvParent = New Infragistics.Web.UI.DataSourceControls.DataView()
            dvParent.ID = "PARENT"
            dvParent.DataSource = tOrders
            dvChild = New Infragistics.Web.UI.DataSourceControls.DataView()
            dvChild.ID = "CHILD"
            dvChild.DataSource = tOrder_details
            hdsMain.DataViews.Add(dvParent)
            hdsMain.DataViews.Add(dvChild)
            Dim drMain As New Infragistics.Web.UI.DataSourceControls.DataRelation()
            drMain.ParentDataViewID = "PARENT"
            drMain.ChildDataViewID = "CHILD"
            drMain.ParentColumns = New String() {"ClassID"}
            drMain.ChildColumns = New String() {"ClassID"}
            hdsMain.DataRelations.Add(drMain)
            WebHierarchicalDataGrid1.DataSource = hdsMain
            WebHierarchicalDataGrid1.DataMember = hdsMain.DataViews.FindByID("PARENT").ID
            WebHierarchicalDataGrid1.DataKeyFields = "ClassID"
            WebHierarchicalDataGrid1.ID = "webgrid"

While running page grid load successfully and shows parent data, but when i try to expand row then its cause javascritp error as 'Sys' is undefined' and 'Object expected'. I use script manager at my master page.

On Same page if i use another WHDataGrid and bind it using templet columns(in desing view), its work fine. Any one help me abt this,

Thakning You.
