DataPager分页问题，ListView重新绑定数据源后DataPager未回到初始页？
如题：
ListView用ObjectDataSource做数据源
当根据查询条件重新绑定后，DataPager没有回到初始页
就是原来我如果选择了第三页，ListView正常显示出来
这时候根据查询条件ListView数据源变了，但是DataPager还是停留在了第三页，怎么让它回到初始页
<asp:HiddenField ID="hf_category" runat="server" />
<div class="alPage">
<asp:DataPager ID="dp_party" runat="server" PagedControlID="repList" PageSize="2"
EnableViewState="false">
<Fields>
<asp:TemplatePagerField>
<PagerTemplate>
共<%= DataCount%>条记录， 当前第<asp:Label runat="server" ID="CurrentPageLabel" Text="<%# Container.TotalRowCount>0 ? (Container.StartRowIndex / Container.PageSize) + 1 : 0 %>" />/<asp:Label
runat="server" ID="TotalPagesLabel" Text="<%# Math.Ceiling ((double)Container.TotalRowCount / Container.PageSize) %>" />页，
</PagerTemplate>
</asp:TemplatePagerField>
<asp:NextPreviousPagerField ButtonType="Link" ShowFirstPageButton="true" ShowPreviousPageButton="true"

</Fields>
</asp:DataPager>
