I have a radgrid with a details table. Both the master table and the details table are using usercontrols for the edit/insert capbilities. Below is the code of the main grid page (I have stripped out unrelated sections):

<telerik:RadGrid ID="grdLibraryGlobalRates" runat="server" DataSourceID="dsLibraryGlobalRateManager"
                                                                    AutoGenerateDeleteColumn="True" AutoGenerateEditColumn="True">
     <MasterTableView CommandItemDisplay="Top" DataSourceID="dsLibraryGlobalRateManager"
            DataKeyNames="_LibraryGlobalRateScheduleID">

                <DetailTables>
                    <telerik:GridTableView Name="grdGlobalRateScheduleEvent"
                                DataKeyNames="_LibraryGlobalRateScheduleEventID"
                                DataSourceID="dsLibraryGlobalRateManagerEvent" Width="100%"
                                 runat="server" AutoGenerateColumns="False" CommandItemDisplay="Top">
                                 <ParentTableRelation>
                                        <telerik:GridRelationFields DetailKeyField="_LibraryGlobalRateScheduleID"
                                            MasterKeyField="_LibraryGlobalRateScheduleID"></telerik:GridRelationFields>
                                 </ParentTableRelation>
                                 .............. Columns here
                                <EditFormSettings EditFormType="WebUserControl"
                                            UserControlName="UserControls_EditUpdate/LibraryGlobalRateEvents.ascx">
                                                <EditColumn FilterControlAltText="Filter EditCommandColumn1 column"
                                                UniqueName="EditCommandColumn1">
                                                </EditColumn>
                                </EditFormSettings>
                     </telerik:GridTableView>
             </DetailTables>
            ............Columns here
        <EditFormSettings EditFormType="WebUserControl" UserControlName="UserControls_EditUpdate/LibraryGlobalRates.ascx">
             <EditColumn FilterControlAltText="Filter EditCommandColumn1 column" UniqueName="EditCommandColumn1">
            </EditColumn>
         </EditFormSettings>
    </MasterTableView>
</telerik:RadGrid>

I have put command names on the update (LibraryGlobalRateEventUpdate) and insert (LibraryGlobalRateEventInsert) buttons on the usercontrol for the details table update. on the main grid item command event I evaluate for the command name and proceed accordingly in the code behind:

Protected Sub grdLibraryGlobalRates_ItemCommand(sender As Object, e As GridCommandEventArgs) Handles grdLibraryGlobalRates.ItemCommand

If e.CommandName = "LibraryGlobalRateEventUpdate" Then

Try

Dim MyUserControl As UserControl = CType(e.Item.FindControl(Telerik.Web.UI.GridEditFormItem.EditFormUserControlID), UserControl)

End If

If e.CommandName = "LibraryGlobalRateEventInsert" Then

Try

Dim MyUserControl As UserControl = CType(e.Item.FindControl(Telerik.Web.UI.GridEditFormItem.EditFormUserControlID), UserControl)

End If

End Sub

On the LibraryGlobalRateEventInsert command, e.item evaluates to

{Telerik.Web.UI.GridEditFormInsertItem} and MyUserControl gets set to the usercontrol I am using for the EditFormSettings

On the LibraryGlobalRateEventUpdate command, e.item evaluates to

{Telerik.Web.UI.GridDataItem} and MyUserControl gets set to Nothing

At this point I am unable to update values when edit is selected.

Please help me resolve this or point me to a post that will explain the update process for details tables as it pertains to UserControls for editing.

Thanks,
Marty
