Output parameters and ASP.NET Datasources

Hello all,

I have a page with a repeater on it that is consuming data from a custom stored procedure. This procedure does paging and handles some funky logic under the hood (otherwise I would have used the built-in version). On my stored proc, I'm returning a dataset that nettiers correctly interprets as a particular type of object. In addition, I'm also returning an integer output parameter (@TotalCount) that is the total number of records that would be returned if I wasn't paging the dataset. I have the following code to declare the datasource on the page:

<data:InventoryDetailDataSource CustomMethodRecordCountParamName="TotalCount" ID="datInventoryDetail" Sort="SortKey" runat="server" SelectMethod="GetByInventoryIDAndInventoryBinID_Paged" EnableDeepLoad="true">
    <DeepLoadProperties Method="includechildren" Recursive="true">
        <Types>
            <data:InventoryDetailProperty Name="InventoryItem" />
            <data:InventoryDetailProperty Name="InventoryItemCategory" />
            <data:InventoryItemProperty Name="MasterItem" />
            <data:MasterItemProperty Name="InventoryUnit" />
            <data:ApplicationEntityGLAccountProperty Name="GLAccount" />
            <data:InventoryItemCategoryProperty Name="ApplicationEntityGLAccount" />
        </Types>
    </DeepLoadProperties>
    <Parameters>
        <asp:QueryStringParameter Name="InventoryID" QueryStringField="InventoryID" Type="Int32" />
        <asp:ControlParameter ControlID="cboInventoryBin" PropertyName="SelectedValue" Type="int32" Name="InventoryBinID" />
        <asp:QueryStringParameter QueryStringField="PageSize" Name="PageSize" DefaultValue="50" Direction="input" Type="int32" />
        <asp:QueryStringParameter QueryStringField="PageNumber" Name="PageNumber" DefaultValue="1" Direction="input" Type="int32" />
        <data:SqlParameter Name="TotalCount" Direction="output" Type="int32" DefaultValue="1" />
    </Parameters>
   </data:InventoryDetailDataSource>

Further down the page, I have a custom control for paging (the code that plays nice with the repeater was already written, so I don't want to rip it back out, as there are multiple nested repeaters with a bunch of javascript around them). The paging control needs the value of the TotalCount parameter that is returned from my custom stored procedure. How can I get the actual value being returned instead of "1"?

Thanks,

Will
