.net GridView分页模板的实例代码

//要在gridview中加入如下属性(前台还是后台看你的习惯了。)

//实现分页

allowpaging="true"

//一页数据10行

 pagesize="10"

// 分页时触发的事件
onpageindexchanging="gvwdesignationname_pageindexchanging"

//在服务器事件里

protected void gvwdesignationname_pageindexchanging(object sender, gridviewpageeventargs e)
{
gvwdesignationname.pageindex=e.newindex;

bingdesignatioonname();
}

//这里我给出一个通用显示分页的模板

<pagertemplate>
                当前第:
                //((gridview)container.namingcontainer)就是为了得到当前的控件
                <asp:label id="labelcurrentpage" runat="server" text="<%# ((gridview)container.namingcontainer).pageindex + 1 %>"></asp:label>
                页/共:
                //得到分页页面的总数
                <asp:label id="labelpagecount" runat="server" text="<%# ((gridview)container.namingcontainer).pagecount %>"></asp:label>
                页
                 //如果该分页是首分页，那么该连接就不会显示了.同时对应了自带识别的命令参数commandargument
                <asp:linkbutton id="linkbuttonfirstpage" runat="server" commandargument="first" commandname="page"
                    visible='<%#((gridview)container.namingcontainer).pageindex != 0 %>'>首页</asp:linkbutton>
                <asp:linkbutton id="linkbuttonpreviouspage" runat="server" commandargument="prev"
                    commandname="page" visible='<%# ((gridview)container.namingcontainer).pageindex != 0 %>'>上一页</asp:linkbutton>
               //如果该分页是尾页，那么该连接就不会显示了
                <asp:linkbutton id="linkbuttonnextpage" runat="server" commandargument="next" commandname="page"
                    visible='<%# ((gridview)container.namingcontainer).pageindex != ((gridview)container.namingcontainer).pagecount - 1 %>'>下一页</asp:linkbutton>
                <asp:linkbutton id="linkbuttonlastpage" runat="server" commandargument="last" commandname="page"
                    visible='<%# ((gridview)container.namingcontainer).pageindex != ((gridview)container.namingcontainer).pagecount - 1 %>'>尾页</asp:linkbutton>
                转到第
                <asp:textbox id="txtnewpageindex" runat="server" width="20px" text='<%# ((gridview)container.parent.parent).pageindex + 1 %>' />页
                //这里将commandargument即使点击该按钮e.newindex 值为3
                <asp:linkbutton id="btngo" runat="server" causesvalidation="false" commandargument="-2"
                    commandname="page" text="go" />
            </pagertemplate>

//对应该事件中代码为

 protected void gvwdesignationname_pageindexchanging(object sender, gridviewpageeventargs e)
    {
        // 得到该控件
        gridview thegrid = sender as gridview;
        int newpageindex = 0;
        if (e.newpageindex==-3)
        {
            //点击了go按钮
            textbox txtnewpageindex = null;

            //gridview较datagrid提供了更多的api，获取分页块可以使用bottompagerrow 或者toppagerrow，当然还增加了headerrow和footerrow
            gridviewrow pagerrow = thegrid.bottompagerrow;

            if (pagerrow != null)
            {
                //得到text控件
                txtnewpageindex = pagerrow.findcontrol("txtnewpageindex") as textbox;   
            }
            if ( txtnewpageindex!= null)
            {
                //得到索引
                newpageindex = int.parse(txtnewpageindex.text) - 1;
            }
        }
        else
        {
            //点击了其他的按钮
            newpageindex = e.newpageindex;
        }
        //防止新索引溢出
        newpageindex = newpageindex < 0 ? 0 : newpageindex;
        newpageindex = newpageindex >= thegrid.pagecount ? thegrid.pagecount - 1 : newpageindex;

        //得到新的值
        thegrid.pageindex = newpageindex;

         //重新绑定
        bingdesignatioonname();
    }
