Hello Leslie,

From your post, my understanding on this issue is: you wonder how to
programmatically change the maximumRows parameter value in a
ObjectDataSource object. If I'm off base, please feel free to let me know.

The defaultValue of asp:Parameter can be set in the .aspx page:

       <asp:ObjectDataSource ID="ObjectDataSource1" runat="server"
OldValuesParameterFormatString="original_{0}"
SelectMethod="ReadDistinguishedName" TypeName="AdInfoBLL">
           <SelectParameters>
               <asp:Parameter DefaultValue="" Name="strStartingFrom"
Type="String" />
               <asp:Parameter DefaultValue="" Name="strLastDisplayName"
Type="String" />
               <asp:Parameter DefaultValue="5" Name="maximumRows"
Type="Int32" />
               <asp:Parameter DefaultValue="2" Name="startRowIndex"
Type="Int32" />
           </SelectParameters>
       </asp:ObjectDataSource>

If you want to change the default value in runtime, we can write the code
as:
this.ObjectDataSource1.SelectParameters["maximumRows"].DefaultValue = "4";
The article GridView Inside GridView
(http://www.vbdotnetheaven.com/UploadFile/nikhil_be_it/GridViewInsideGridVie
w05232006004636AM/GridViewInsideGridView.aspx) shows how to do it in
code-behind.

Attached is another small sample website for you to demonstrate how to
programmatically change the maximumRows parameter value. You can download
it with Outlook Express or Windows Mail, and see if the sample code helps
with your problem.

I have been trying to reproduce the issue "The function is called but
maximumRows is always set to -1 regardless of what default value I set.".
However I need more information about how you set the Parameter's default
value in your current code. Is the DefaultValue set in aspx page or
code-behind? Would you paste some codes about how you set the DefaultValue?
