自己写的Gridview分页功能

先写个Pages.cs类  最好放在App_Code里

Code

 79        switch (arg)
 80        {

    public static void PagerButtonClickGrive(object sender, EventArgs e, GridView dg, Label lblCurrentIndex, Label lblPageCount)

                break;
        }
        ShowStatsGrive(lblCurrentIndex, lblPageCount, dg);
    }
}

然后在页面的cs文件里

 protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            Pages.gridViewProperty(GridView1);
        getData(); //此行是我的gridview方法 根据你实际的写
            Pages.ShowStatsGrive(lblCurrentIndex, lblPageCount, this.GridView1);
        }     
    }

protected void PagerButtonClick(object sender, EventArgs e)
    {
        Pages.PagerButtonClickGrive(sender, e, this.GridView1, lblCurrentIndex, lblPageCount);

        getData();
    }

在源里gridview代码的下面
 </tr>
        <tr>
  
            <td align="right"  bgcolor="#F3F8FC" style="height: 41px" ><table width="100%" border="0">
