I have a grid with a NestedViewTemplate, and in the template I am displaying a databound TabStrip. The DataSource for the tabStrip is part of the template. Generally the template works, however, I am getting a very strange rendering issue the first time I open a Nested view. The tab strip does not render correctly, I am getting some strange characters and the Label and image of the last tab rather than the TabStrip control.
After collapsing and re-opening the Nested View everything works correctly and all Nested views display correctly. Even after refreshing the grid, it will display correctly. After reloading the page, I am getting the same issue the first time the nested view is displayed. Any ideas?

Here is my Grid definition:

<telerik:RadGrid ID="grdPages" runat="server" AutoGenerateColumns="false" AllowPaging="true"

OnNeedDataSource="grdPages_NeedDataSource" Width="100%" Skin="Office2007"

OnDetailTableDataBind="grdPages_DetailTableDataBind">

<MasterTableView TableLayout="Fixed" Caption="Quick Data Entry Path Screens" CommandItemDisplay="Top" DataKeyNames="Pages_Id,QuickDataEntryPath_Id">

<PagerStyle AlwaysVisible="true" Position="Bottom" Mode="NumericPages" />

<Columns>

<telerik:GridEditCommandColumn ButtonType="ImageButton">

<HeaderStyle Width="30px" />

<ItemStyle HorizontalAlign="Center" />

</telerik:GridEditCommandColumn>

<telerik:GridBoundColumn DataField="Order" HeaderText="Page Order">

<HeaderStyle Width="90px" />

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="Name" HeaderText="Page Title">

<telerik:GridBoundColumn DataField="Description" HeaderText="Description">
