Batch EditMode and Nested/Detail Templates

[josh]

Hello,

I have a grid in batch edit/cell mode, and everything works.

My problem is that one of the fields is very large - potentially two or three paragraphs of text. I'd like to move this onto it's own row, if possible. I've tried using a radtextbox within a NestedViewTemplate and DetailItemTemplate, and I can get the data to display in both, but I can't figure out how to include it in batch saves. <%#Bind("FieldName")%> doesn't work. 

What would be the best way to accomplish this?

Here's a sample of what I have:

<telerik:RadGrid ID="RadGrid1" runat="server" AllowAutomaticUpdates="true" AutoGenerateColumns="false" DataSourceID="DataSource1">
    <MasterTableView CommandItemDisplay="TopAndBottom" DataKeyNames="ItemNumber" EditMode="Batch" AutoGenerateColumns="false"
       DataSourceID="DataSource1">
       <BatchEditingSettings EditType="Cell" HighlightDeletedRows="true" />
       <NestedViewTemplate>
            <telerik:RadTextBox ID="txtDesc" runat="server" Text='<%#Bind("Desc")%>' />
        </NestedViewTemplate>
        <Columns>
            <telerik:GridBoundColumn UniqueName="ItemNumber" DataField="ItemNumber" HeaderText="Item Number" />
        </Columns>
    </MasterTableView>
 </telerik:RadGrid>
 <asp:SqlDataSource runat="server" ID="DataSource1" ConnectionString="(ConnectionString)" ConflictDetection="OverwriteChanges"
    SelectCommand="SELECT * FROM [Table]"
    InsertCommand="INSERT INTO [Table] ([Name], [Desc]) VALUES (@Name, @Desc)"
    UpdateCommand="UPDATE [Table] SET [Name]=@Name, [Desc]=@Desc WHERE [ItemNumber]=@ItemNumber">
    <InsertParameters>
        <asp:Parameter Name="Name" Type="String" />
        <asp:Parameter Name="Desc" Type="String" />
    </InsertParameters>
    <UpdateParameters>
        <asp:Parameter Name="Name" Type="String" />
        <asp:Parameter Name="Desc" Type="String" />
        <asp:Parameter Name="ItemNumber" Type="Int32" />
    </UpdateParameters>
 </asp:SqlDataSource>
