Actually you should be using the OnSelecting event.

What happens is that ObjectDataSource calls the method SelectMethod twice

1. First time it gets the data.
2. Next time it gets the count.

So I think you have to implement the OnSelecting event

<asp:ObjectDataSource ID="ODS" runat="server" SelectMethod="GetList" SelectCountMethod="GetListCount" 
    OnSelecting="ods_Selecting">
    TypeName="Website.Test" EnablePaging="true" /> 

and then cancel the event when the ObjectDataSource tries to call the count method.

 protected void ods_Selecting(object sender,
                ObjectDataSourceSelectingEventArgs e)
 {
      if (e.ExecutingSelectCount)
      {
           //Cancel the event   
           return;
      }
}

You can use the link below so that another db call is not made to fetch the count. http://www.unboxedsolutions.com/sean/archive/2005/12/28/818.aspx
