在Paga_Load里自己写SQL语句来得到数据，绑定到GridView1上，如何实现GV1的分页功能？

Question

如上，我在页面加载时创建临时表，然后页面显示出来后没有分页功能，于是我回去程序里把“启用分页”选上（在GV1控件上），运行后有分页效果，但是我单击页2时，出错！
GridView“GridView1”激发了未处理的事件“PageIndexChanging”。 
请大家指教！

Answer 1

protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
    {
        this.GridView1.PageIndex = e.NewPageIndex;
        this.filldatatodatagrid();
    }

Answer 2

protected void GridView1_RowEditing(object sender, GridViewEditEventArgs e)
    {
        this.GridView1.EditIndex = e.NewEditIndex;
        this.filldatatodatagrid();
    }
    protected void GridView1_RowCancelingEdit(object sender, GridViewCancelEditEventArgs e)
    {
        this.GridView1.EditIndex = -1;
        this.filldatatodatagrid();
    }filldatatodatagrid（）方法是刷新方法。

自定义分页代码：#region GridView1页码跳转
        protected void link_next_Click(object sender, EventArgs e)
        {
            if (GridView1.PageIndex < GridView1.PageCount)
                GridView1.PageIndex++;
            CheckPager();
            ShowPageIndex();
            GridBind();
        }        protected void linke_pre_Click(object sender, EventArgs e)
        {
            if (GridView1.PageIndex > 0)
                GridView1.PageIndex--;
            CheckPager();
            ShowPageIndex();
            GridBind();
        }        protected void link_frist_Click(object sender, EventArgs e)
        {
            GridView1.PageIndex = 0;
            CheckPager();
            ShowPageIndex();
            GridBind();
        }        protected void link_last_Click(object sender, EventArgs e)
        {
            GridView1.PageIndex = GridView1.PageCount - 1;
            CheckPager();
            ShowPageIndex();
            GridBind();
        }        protected void img_goto_Click(object sender, ImageClickEventArgs e)
        {
            int page_num = 0;
            if (this.txt_pagenum.Text != string.Empty)
            {
                try
                {
                    page_num = Convert.ToInt32(this.txt_pagenum.Text);
                    if (page_num > 0 && page_num <= GridView1.PageCount)
                        this.GridView1.PageIndex = page_num - 1;
                }
                catch
                {
                    page_num = this.GridView1.PageIndex;
                }
                CheckPager();
                ShowPageIndex();
                GridBind();
            }
        }
        public void ShowPageIndex()
        {
            if (this.GridView1 != null)
            {
                this.img_goto.Enabled = true;
                if (this.GridView1.PageCount != 0)
                {
                    pagenum = Convert.ToString(GridView1.PageIndex + 1);//给参数赋页码值

                    this.img_goto.Enabled = true;
                }
                else
                {
                    pagenum = Convert.ToString(GridView1.PageIndex + 1);//给参数赋页码值
                    this.lab_pageindex.Text = Convert.ToString(GridView1.PageIndex) + "/" + this.GridView1.PageCount.ToString();
                    this.img_goto.Enabled = false;
                }                //this.txt_pagenum.Text = Convert.ToString(GridView1.PageIndex + 1);
                CheckPager();
            }
            else
            {
                this.lab_pageindex.Text = "0/0";
                this.img_goto.Enabled = false;

            }
        }
        private void CheckPager()
        {
            if (GridView1.PageIndex <= 0)
            {
                this.link_frist.Enabled = false;
                this.linke_pre.Enabled = false;
            }
            else
            {
                this.link_frist.Enabled = true;
                this.linke_pre.Enabled = true;
            }
            if (GridView1.PageIndex >= GridView1.PageCount - 1)
            {
                this.link_next.Enabled = false;
                this.link_last.Enabled = false;
            }
            else
            {
                this.link_next.Enabled = true;
                this.link_last.Enabled = true;
            }
        }
        #endregion

Answer 4

protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e) 
    { 
        this.GridView1.PageIndex = e.NewPageIndex; 
        this.filldatatodatagrid(); 
    }
加这个以后看看,现在分页一般都自己做个分页控件.

Answer 5

protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
    {
        GridView1.PageIndex = e.NewPageIndex;
        从新绑定GridView1；
    }
