ObjectDataSource maximumRows always = -1

[Leslie]

I am using an ObjectDataSource control to provide data to a GridView control.
I have "AllowPaging" set to true for the GridView.

The Select statement for the ODS is below:
public List<AdInfo> ReadDistinguishedName(string strStartingFrom,
string strLastDisplayName, int maximumRows, int startRowIndex)

The function is called but maximumRows is always set to -1 regardless of
what default value I set. I have attempted to set a default value for
maximumRows in the Parameter Collection Editor but the value I set never
appears as the value for maximumRows when the method is called.

How can I set the value for maximumRows (preferrably programmatically) so
the value I set will be the value used in the call to the Select statement?

Thanks,

Leslie

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 asparameter can be set in the .aspx page:

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