Sorry about the delay in coming back back to this - been out ill & other newer work priorities.
So, - something so very simple. Made the mistake of assuming that "no one would ever do (or NOT do) that" and as programmers we ought to know better than to make that assumption, right? Anyhow, I had to add the <SelectParameters>
back into ObjectDataSource
in the aspx
page:
<asp:ObjectDataSource ID="odsItInventory" runat="server" SelectMethod="BindGrid"
TypeName="ADRUO.GUI.UserControls.ExtendedInventoryGridUserControl">
<SelectParameters>
<asp:SessionParameter Name="User" Type="Object" SessionField="CurrentUser" />
</SelectParameters>
</asp:ObjectDataSource>
Thank you for the assistance - all of your comments were helpful, I believe each answer would have worked, had I had those parameters in the page. As it was, the param add was all that was required to resolve.
