how to handle next and prev in datapager

Question

I was bind all data in DB to the datapager repeater from Entity framwork linq . and every thing works fine but the system was slow so i tried to bind each 10 data separately to the data pager but the problem i faced is i can't handle next and prev in Datapager in order to bind 10 rows in each page !!

here's the aspx page :

<asp:DataPager ID="pager" 
               runat="server" 
               PagedControlID="repMeetings" 
               PageSiz="10" 
               EnableViewState="true">
    <Fields>
        <asp:NextPreviousPagerField ShowLastPageButton="false" 
                                    ShowNextPageButton="false"
                                    RenderDisabledButtonsAsLabels="true" 
                                    ShowPreviousPageButton="true" 
                                    ButtonType="Link"
                                    ButtonCssClass="prev" 
                                    PreviousPageText='<%$resources:CompaniesViewMessages,PREVIOUS %>' 
                                    ShowFirstPageButton="true"
                                    FirstPageText="<<" />
        <asp:NumericPagerField CurrentPageLabelCssClass="current" 
                               ButtonCount="5" 
                               NumericButtonCssClass="nubmers" />
        <asp:NextPreviousPagerField ShowFirstPageButton="false" 
                                    ShowNextPageButton="true"
                                    ShowPreviousPageButton="false"

                                    ShowLastPageButton="true"
                                    LastPageText=">>"
