I am trying to do the following in a RadGrid with a MasterTableView and a Detail GridTableView:

1) User clicks EDIT on a parent row
2) Parent row goes into EDIT mode
3) Child rows, if any, also go into EDIT mode
4) Child rows are displayed automatically if parent row goes into EDIT mode

I have looked at and tried all of the currently posted methods for putting items (parent or child) into edit mode, including adding code to the PreRender event to add all of the child item indexes to the RadGridEditIndexes collection for the grid and rebinding without success.  If I put the code in the PreRender event, the indexes are properly added to the RadGrid.EditIndexes collection but a straight call to RadGrid.Rebind doesn't render the child rows.  If I, instead, call RadGrid.MasterTableView.DetailTables(0).Rebind, the detail rows are rendered but they are not in edit mode.  (I have also tried adding my code to the ItemCommand and EditCommand events for the grid, but these do not work either...)

As a test, I commented out my PreRender code and added a GridEditCommandColumn to the Detail GridTableView.  I am able to expand/collapse the parent, click edit on the parent and then click edit on its children - they all go into EDIT mode after their respective EDIT buttons have been clicked, so I know it's possible to get them to all show up in EDIT mode...

Any thoughts on how to accomplish this task is much appreciated, as I've spent 3 very unfruitful days trying to make it work.  Thanks!

Notes: I have AllowMultiRowEdit set to TRUE for the grid, databinding is done server-side and I used the NeedDataSource event for databinding.

Here's my PreRender code:

 

Protected Sub grdUsers_PreRender(ByVal sender As Object, ByVal e As System.EventArgs) Handles grdUsers.PreRender
        Try
            If (Me.ProjectID > 0) Then
                Dim editItems() As Telerik.Web.UI.GridItem = grdUsers.MasterTableView.GetItems(Telerik.Web.UI.GridItemType.EditItem)
                For intCounter As Int32 = 0 To (editItems.Length - 1)
                    editItems(intCounter).Edit = True
                    editItems(intCounter).Expanded = True
                    If editItems(intCounter).HasChildItems Then
                        Dim customFields As Telerik.Web.UI.GridTableView = grdUsers.MasterTableView.Items(editItems(intCounter).ItemIndex).ChildItem.NestedTableViews(0)
                        If Not (customFields Is Nothing) Then
                            For Each fld As Telerik.Web.UI.GridItem In customFields.Items
                                grdUsers.EditIndexes.Add(editItems(intCounter).ItemIndex, grdUsers.MasterTableView.DetailTables(0).DetailTableIndex, fld.ItemIndex)
                            Next fld
                        End If
                        editItems(intCounter).SetChildrenVisible(True)
                    End If
                Next intCounter
                If (editItems.Length > 0) Then
                    grdUsers.MasterTableView.DetailTables(0).DataSource = Nothing
                    grdUsers.MasterTableView.DetailTables(0).Rebind()
                End If
            End If
        Catch ex As Exception
            Throw New Exception("Error in grdUsers_PreRender() of module usrctrl_ProjectUsers: <br />" & ex.ToString)
        End Try
    End Sub
