hi,

i am using the telerik rad grid my code is as follows please see the code . i am using the dataset with the relations for hierarchy that code is like this i am using vb.net and telerik q3 version when i click on the edit the row is in edit mode but when i click on the update it did not go to ItemUpdated event why? all of your examples are based on objectect datasource or sql data data source please give at least one example with dataset or data table that is really good for programmers .

i wrote like this

Protected Sub dgproduct_ItemUpdated(ByVal source As Object, ByVal e As Telerik.Web.UI.GridUpdatedEventArgs) Handles dgProduct.ItemUpdated
        Dim item As String = getItemName(e.Item.OwnerTableView.Name)
        Dim field As String = getFieldName(e.Item.OwnerTableView.Name)
        If Not e.Exception Is Nothing Then
            e.KeepInEditMode = True
            e.ExceptionHandled = True
            DisplayMessage(item + " " + e.Item(field).Text + " cannot be updated. Reason: " + e.Exception.Message)
        Else
            DisplayMessage(item + " " + e.Item(field).Text + " updated")
        End If
    End Sub

ds = ProductBO.GetProductChainDetailsList(ddlCategory.SelectedValue, "", txtStyle.Text, ddlStyleActive.SelectedValue, CInt(ViewState("cp").ToString), CInt(SystemSettingsBO.GetSettings("PageSize")))

ds.Relations.Add("ProductRelation", ds.Tables(0).Columns("PKProductID"), ds.Tables(1).Columns("FKProductID"))

If Not ds.Tables(2) Is Nothing Then

If ds.Tables(2).Rows.Count > 0 Then

ds.Relations.Add("ProductRelation2", ds.Tables(1).Columns("PKProductID"), ds.Tables(2).Columns("FKProductID"))

End If

'dgProduct.DisplayLayout.AllowUpdateDefault = AllowUpdate.Yes

dgProduct.DataSource = ds

dgProduct.DataBind()
