girdview 分页PageIndexChanging

修改方法：一要在girdview 后面加 OnPageIndexChanging="GridView1_PageIndexChanging

                二要cs页面中添加

    protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)

    {

        GridView1.PageIndex = e.NewPageIndex;

        DataBind();

    }

 OK问题解决！！

  下面的是一个比较齐全的分页代码， 

 protected void Page_Load(object sender, EventArgs e)

    {

        btnFirst.Text = "最首页";

        btnPrev.Text = "前一页";

        btnNext.Text = "下一页";

        btnLast.Text = "最后页";

        GridView1.DataBind();

        ShowPageChangedStatus();

    }

   private void ShowPageChangedStatus()

    {

        lblCurrentIndex.Text = "第" + (GridView1.PageIndex + 1).ToString() + "页";

        lblPageCount.Text = "总共 " + GridView1.PageCount.ToString() + " 页";

    }

    public void PagerButtonClick(object sender, EventArgs e)

    {

        string arg = ((LinkButton)sender).CommandArgument.ToString();

        switch (arg)

        {

            case "next":

                if (GridView1.PageIndex < (GridView1.PageCount - 1))

                {

                    GridView1.PageIndex += 1;

                }

                break;

            case "prev":

                if (GridView1.PageIndex > 0)

                {

                    GridView1.PageIndex -= 1;

                }

                break;

            case "last":

                GridView1.PageIndex = (GridView1.PageCount - 1);

                break;

            default:

                GridView1.PageIndex = System.Convert.ToInt32(arg);

                break;

        }

        GridView1.DataBind();

        ShowPageChangedStatus();

    }

    protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)

    {

        int startIndex;

        startIndex = GridView1.PageIndex * GridView1.PageSize;

        GridView1.PageIndex = e.NewPageIndex;

        GridView1.DataBind();

        ShowPageChangedStatus();

    }
