AspNetPager分页控件UrlRewritePattern参数设置的重写代码

代码如下:
<AspNet:AspNetPager ID="AspPages" runat="server" CustomInfoHTML="第%CurrentPageIndex%/%PageCount%页，每页%PageSize%条，共%RecordCount%条"
                            FirstPageText="首页" LastPageText="尾页" NextPageText="下一页" AlwaysShow="true" CssClass="PP"
                            CurrentPageButtonClass="cpb" PageIndexBoxType="DropDownList" PrevPageText="上一页"
                            ShowCustomInfoSection="Left" ShowPageIndexBox="Never" SubmitButtonText=" Go "
                            TextAfterPageIndexBox="页" PageSize="10" TextBeforePageIndexBox="转到" Height="25px"
                            NumericButtonCount="4" Width="98%" CenterCurrentPageButton="True" CustomInfoTextAlign="Left"
                            HorizontalAlign="Right" OnPageChanged="AspPages_PageChanged"
　　　　　　　　　　　　　　　　UrlRewritePattern="/Knowledge/Tag/%TagID%/%Category%/pv{0}" UrlPaging="True" EnableUrlRewriting="True">
   </AspNet:AspNetPager>

protected void AspPages_PageChanged(object sender, EventArgs e)
{
string TagID = GetRequest.GetString("TagID");
AspPages.UrlRewritePattern = string.IsNullOrEmpty(TagID) ? "/Knowledge/Tag/%TagID%/%Category%/pv1" : "/Knowledge/Tag/%TagID%/%Category%/pv{0}";
BindRptChateau(TagID);
}
<rewrite url="^/Knowledge/Tag/(\d+)/(\d+)/pv(\d+)$" to="~/Search/SearchKnowledgeTag.aspx?Keywords=$1&TagID=$1&Category=$2&page=$3" processing="stop"></rewrite>
