Question

I have a gridview that receives a data source with 8621 entries with the page size set to 20. The first page is displayed exactly as it should be. I click the link to display page 2, and it also displays as it should. Anything after that however is still page 2. So if I click the link to go to page 3, the paging control updates saying I am on page 3, but the data displayed is the data on page 2. I know the gridview is getting all 8621 entries because if I change the page size to 200 it displays those 200. Why would the gridview work correctly for some pages but not others? Anyways, enough with my rambling, here is the code itself:

<ajax:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">
<cb:SortedGridView ID="SearchUsersGrid" runat="server" AutoGenerateColumns="False" DataKeyNames="Email" 
  DefaultSortDirection="Ascending" DefaultSortExpression="Email"
  AllowPaging="true" PageSize="20" AllowSorting="true" Width="100%" SkinID="PagedList">
<Columns>
<asp:TemplateField HeaderText="In List">
  <ItemStyle HorizontalAlign="Center" />
  <ItemTemplate>
    <asp:CheckBox ID="IsInEmailList2" runat="server" checked='<%#IsInEmailList(Container.DataItem)%>' OnCheckedChanged="IsInEmailList_CheckedChanged" AutoPostBack="true" ></asp:CheckBox>
  </ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Email" SortExpression="Email">
  <HeaderStyle HorizontalAlign="Left" />
     <ItemStyle HorizontalAlign="Left" />
      <ItemTemplate>
       <asp:HyperLink ID="NameLink2" runat="server" Text='<%# Eval("Email") %>' NavigateUrl='<%#GetEditUserUrl(Container.DataItem)%>'></asp:HyperLink>
      </ItemTemplate>
      </asp:TemplateField>
<asp:TemplateField HeaderText="Name" SortExpression="LastName">
  <HeaderStyle horizontalalign="Left" />
     <ItemStyle horizontalalign="Left" />
        <ItemTemplate>
          <asp:Label ID="FullNameLabel2" runat="server" Text='<%#GetFullName(Container.DataItem)%>'></asp:Label>
         </ItemTemplate>
</asp:TemplateField>
</Columns>
<EmptyDataTemplate>
  <div align="center">
    <asp:Label runat="server" ID="noUsersFound" enableViewState="false" Text="No matching users found."/>
  </div>
 </EmptyDataTemplate>
 </cb:SortedGridView>
 </ajax:UpdatePanel>

and some relevant code behind:

    SearchUsersGrid.Visible = true;
    SearchUsersGrid.DataSourceID = "SearchUsersDs";
    SearchUsersGrid.DataBind();

and the data source itself

<asp:ObjectDataSource ID="SearchUsersDs" runat="server" OldValuesParameterFormatString="original_{0}" SelectMethod="FindUsersByName" TypeName="Builder.Users.UserDataSource"
  SelectCountMethod="CountUsersByName" EnablePaging="True" SortParameterName="sortExpression" DataObjectTypeName="Builder.Users.User" DeleteMethod="Delete">
 <SelectParameters>
     <asp:ControlParameter ControlID="SearchText" Name="searchPattern" PropertyName="Text" Type="String" />
     <asp:ControlParameter ControlID="SearchByDropDown" Name="searchField" PropertyName="SelectedValue" Type="Object" />
</SelectParameters>
</asp:ObjectDataSource>

There is no PageIndexChanged event. Any ideas?

I think the issue had to do with our production server. for some reason the code works great on our production box (even with the same data).
