[Solved] Grid not updating after datasource update

[bill]

When selected index changes, I populate several fields out side the grid.  The user can then make changes to a couple of the fields.  Also outside the grid is a save button, that sends changes to the database.  Inside the save button's click event I call the grid's rebind method.  This in turn calls the grid's NeedDataSource event handler.  I set a break in this method, I can see the updated data in the datatable.  I set the grid's datasource property equal to the datatable.  I expect the data in the grid to be updated, but nothing happens.

This looks to be an issue when the panel the button is located in, is specified in the RadAjaxManager's Updated controls.  I put together a simple example:

        <asp:ScriptManager ID="ScriptManager1" runat="server">
        </asp:ScriptManager>
    <div>
        <telerik:RadGrid ID="RadGrid1" runat="server" GridLines="None">
            <MasterTableView>
                <RowIndicatorColumn>
                    <HeaderStyle Width="20px" />
                </RowIndicatorColumn>
                <ExpandCollapseColumn>
                    <HeaderStyle Width="20px" />
                </ExpandCollapseColumn>
            </MasterTableView>
            <FilterMenu EnableTheming="True">
                <CollapseAnimation Duration="200" Type="OutQuint" />
            </FilterMenu>
        </telerik:RadGrid>
        </div>
        <asp:Panel ID="Panel1" runat="server">
        <asp:Button ID="Button1" runat="server" Text="Update" /></asp:Panel>
        <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
            <AjaxSettings>
                <telerik:AjaxSetting AjaxControlID="RadGrid1">
                <UpdatedControls>
                <telerik:AjaxUpdatedControl ControlID="RadGrid1" />
                 <telerik:AjaxUpdatedControl ControlID="Panel1" />
                </UpdatedControls>
             </telerik:AjaxSetting>
            </AjaxSettings>
        </telerik:RadAjaxManager>

    Protected Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        RadGrid1.Rebind()
    End Sub

    Private Sub RadGrid1_NeedDataSource(ByVal source As Object, ByVal e As Telerik.Web.UI.GridNeedDataSourceEventArgs) Handles RadGrid1.NeedDataSource
        Dim myTable As New DataTable
        myTable.Columns.Add("Time")
        myTable.Rows.Add(New String() {Date.Now.ToString("hh:mm:ss")})
        RadGrid1.DataSource = myTable
    End Sub

Hello bill,

Please change this setting to:
            <AjaxSettings>
                <telerik:AjaxSetting AjaxControlID="Panel1"> 
                  <UpdatedControls>
                    <telerik:AjaxUpdatedControl ControlID="Panel1" />
                  </UpdatedControls>
             </telerik:AjaxSetting>
            </AjaxSettings>
