FrameSet框架下,repeater和aspnetpager一起使用的问题

点击aspnetpager分页的时候希望 只有repeater刷新.
页面刷新的时候 希望aspnetpager不刷新 
怎么实现？现在的代码是这样的. <asp:Repeater ID="RepeaterShow" runat="server" OnItemDataBound="RepeaterShow_ItemDataBound">
                <HeaderTemplate>
                    <div style="overflow-x: auto; height: 600px;">
                        <table width="100%" class="tableselect" id="tableshow" align="center" border="1px"
                            style="text-align: center">
                </HeaderTemplate>
                <ItemTemplate>
                    <tr onmouseover="this.style.backgroundColor='#CCCCFF'" onmouseout="this.style.backgroundColor=''"
                        ondblclick="FN_UpdateFilePath(this,'',450,300)" value='<%#Eval("FileId") %>'>
                        <td width="5%">
                            <input id="item" type="checkbox" name="itemname" />
                        </td>
                        <td width="5%">
