在 Gridview 分页上添加“上一页，下一页，共X页”等信息

原理比较简单，


就是利用GridView 在RowCreated事件上做个手脚，


当if (e.Row.RowType == DataControlRowType.Pager) 时


加入几个Button 和Label 之后再给他们写个事件就ok了


当然我觉得最有意思的就是最后的pager里面的对象嵌套。。。


拉出来一句


e.Row.Controls[0].Controls[0].Controls[0].Controls[0].Controls.AddAt(0, (Button_IndexFirst));


其中各个对象的含义，这里只做个参考给大家

Pannel对象->Table对象->TableRow对象->TableCell对象    恩 貌似是这样的。


雕虫小技，以博众高手一笑


以下是代码


//注意：GridView 必须开启分页功能，并启用RowCreated 事件


C#

protected void GridView1_RowCreated(object sender, GridViewRowEventArgs e)
{
    #region 翻页绑定
    if (e.Row.RowType == DataControlRowType.Pager)
     {
         Label label_Index = new Label();
         LinkButton Button_IndexFirst = new LinkButton();
         LinkButton Button_IndexLast = new LinkButton();
         LinkButton Button_IndexNext = new LinkButton();
         LinkButton Button_IndexPrevious = new LinkButton();

         Button_IndexFirst.Text = "第一页 ";
         Button_IndexFirst.CommandName = "first";
         Button_IndexFirst.ForeColor = Color.White;
         Button_IndexFirst.Click +=new EventHandler(PageButtonClick);

         Button_IndexNext.Text = "   下一页 ";
         Button_IndexNext.CommandName = "next";
         Button_IndexNext.ForeColor = Color.White;
           
         Button_IndexNext.Click += new EventHandler(PageButtonClick);

         Button_IndexPrevious.Text = "前一页 ";
         Button_IndexPrevious.CommandName = "previous";
         Button_IndexPrevious.ForeColor = Color.White;
         Button_IndexPrevious.Click += new EventHandler(PageButtonClick);

         Button_IndexLast.Text = "最末页 ";
         Button_IndexLast.CommandName = "last";
         Button_IndexLast.ForeColor = Color.White;
         Button_IndexLast.Click += new EventHandler(PageButtonClick);
           
         label_Index.Text ="当前为第" + (GridView1.PageIndex + 1) + "页,共有"+((GridView)sender).PageCount+"页";
         e.Row.Controls[0].Controls[0].Controls[0].Controls[0].Controls.AddAt(0, (Button_IndexFirst));
         e.Row.Controls[0].Controls[0].Controls[0].Controls[0].Controls.AddAt(1, (Button_IndexPrevious));

        int controlTmp = e.Row.Controls[0].Controls[0].Controls[0].Controls.Count-1;
         e.Row.Controls[0].Controls[0].Controls[0].Controls[controlTmp].Controls.Add(Button_IndexNext);
         e.Row.Controls[0].Controls[0].Controls[0].Controls[controlTmp].Controls.Add(Button_IndexLast);

         e.Row.Controls[0].Controls[0].Controls[0].Controls[controlTmp].Controls.Add(label_Index);

        //e.Row.Controls[0].Controls.Add(label_Index);
     }
    #endregion
}

     LinkButton clickedButton = ((LinkButton)sender);
    if (clickedButton.CommandName == "first")

         GridView1.PageIndex = 0;
     }
    else if (clickedButton.CommandName == "next")
