Asp.net GridView中的分页未显示

我有GridView，这个网格设置了分页，但是这个分页没有显示。。。我怎样才能修好它

<asp:ObjectDataSource ID="odsUzivatele" runat="server" SelectMethod="VratUzivatele" 
    TypeName="ManagerUzivateleAdapter"></asp:ObjectDataSource>
<asp:GridView ID="gwUzivatele" runat="server" 
    DataSourceID="odsUzivatele" onrowdatabound="gwUzivatele_RowDataBound" 
    AllowPaging="True" PageSize="5" EnableModelValidation="True">
</asp:GridView>

问题在RowDataBound事件中，我显示了第一个（索引0）单元格。。。删除此事件后，将显示分页。。。。 谢谢你的答复。：）

您的数据中实际有超过5行吗？ObjectDataSource返回哪种类型？他说分页不会显示。所以这不是他目前的问题。

<asp:GridView ID="grdList" runat="server" AutoGenerateColumns="False" 

            GridLines="None" PageSize="4" AllowPaging="True"
            EmptyDataText="No record found" 
            onpageindexchanging="grdList_PageIndexChanging"

    protected void grdList_PageIndexChanging(object sender, GridViewPageEventArgs e)    
    {
        grdList.PageIndex = e.NewPageIndex;
        fillgrid();
    }

<asp:GridView
                    ID="gvFercDocket" runat="server" AllowPaging="True" AllowSorting="True"
                    AutoGenerateColumns="True" DataKeyNames="FERCDocket_Id" CssClass="tableHeader"
                    DataSourceID="EDSFERCDocket" Width="900px" ShowFooterWhenEmpty="true" ShowHeaderWhenEmpty="true"
                    ShowFooter="true" ShowHeader="true" OnRowCreated="gvFercDocket_RowCreated" PageSize="10">
                    <PagerSettings PageButtonCount="10" Visible="False" />
