Hi there,

I'm having a difficult time getting the WebHierarchicalDataGrid to work properly.  I've added one to a test page and without any code in the code behind file to bind any data to it, I get this error message:

The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>).

I initially had tried binding some items to the collection, then leaving the call to databind out, then finally removing all code from the code behind and I still get this error.  Does anyone know what's causing it?  Code below - it's pulled directly from your samples page.

<ig:WebHierarchicalDataGrid ID="dg" runat="server" AutoGenerateColumns="false" AutoGenerateBands="true" InitialExpandDepth="0" InitialDataBindDepth="-1" Height="450" Width="700px" DataKeyFields="SupplierID">
        <ExpandCollapseAnimation SlideOpenDirection="Auto" SlideOpenDuration="300" SlideCloseDirection="Auto" SlideCloseDuration="300" />
        <Columns>
            <ig:BoundDataField DataFieldName="SupplierID" Key="SupplierID" Header-Text="Supplier ID" />
            <ig:BoundDataField DataFieldName="CompanyName" Key="Company" Header-Text="Company" Width="230px" />
            <ig:BoundDataField DataFieldName="ContactName" Key="Contact" Header-Text="Contact" Width="150px" />
            <ig:BoundDataField DataFieldName="Region" Key="Region" Header-Text="Region" Width="80px" />
        </Columns>
    </ig:WebHierarchicalDataGrid>

Thanks!
