                                <asp:boundfield datafield="p_on" headertext="是否开启" sortexpression="p_on" itemstyle-horizontalalign="center"  >

                        </columns>
                        <emptydatatemplate>
                        没有数据！
                        </emptydatatemplate>
                         <pagertemplate>
                        <table width="100%" class="gvpage" style="font-size:12px;">
                            <tr>
                            <td style="text-align: right">
                                第<asp:label id="lblpageindex" runat="server" text='<%# ((gridview)container.parent.parent).pageindex + 1 %>'></asp:label>页
                                /共<asp:label id="lblpagecount" runat="server" text='<%# ((gridview)container.parent.parent).pagecount %>'></asp:label>页  
                              <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>
                              <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>

                              <asp:linkbutton id="btngoex" runat="server" commandargument="go" commandname="page" text="go" onclick="btngoex_click"></asp:linkbutton>
                            </td>
                            </tr>
                        </table>
                    </pagertemplate>
                 </asp:gridview>

后端的话，由于需要弹出删除前的确认框，所以，我们需要在rowdatabound里面做点什么？同时，要想真正的删除，还需要触发rowdeleting事件，具体代码如下：

复制代码代码如下:

//报警删除
        protected void gridviewdxjk_rowdeleting(object sender, gridviewdeleteeventargs e)
        {
            string key = gridviewdxjk.datakeys[e.rowindex].value.tostring();
            bool flag = bll.delete(int32.parse(key));
            if (flag)
                nxt_wlservice.app_code.jscript.alert("删除成功！", this);
            else
                nxt_wlservice.app_code.jscript.alert("删除失败！", this);
        }

        protected void gridviewdxjk_rowdatabound(object sender, gridviewroweventargs e)
        {
            if (e.row.rowtype == datacontrolrowtype.datarow)
            {
                linkbutton btn = (linkbutton)e.row.cells[1].controls[0];
                if (btn.text.equals("删除"))//刪除鈕才加提示訊息
                    btn.onclientclick = "if (confirm('你确认要删除?')) javascript:__dopostback('gridviewdxjk','delete$" + e.row.rowindex.tostring() + "'); else return false;";
            }
        }
