本文介绍了ASP.NET中GridView控件的数据绑定、分页及排序功能实现方法，并演示了如何通过代码隐藏列并确保数据仍然可被正确读取。

基本上就是三种方法即可完成此操作：

protected void BindGrid()//数据绑定操作
        {
            DataView dv = dt.DefaultView;
            if (ViewState["sortexpression"] != null)//这个是对分页操作部分的处理
            {
                dv.Sort = ViewState["sortexpression"].ToString() + " " + ViewState["sortdirection"].ToString();
            }

            GridView1.DataSource = dv;
            GridView1.DataBind();
        }
        protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e) //分页操作函数
        {
            GridView1.PageIndex = e.NewPageIndex;
            BindGrid();
        }
        protected void GridView1_Sorting(object sender, GridViewSortEventArgs e)//排序操作函数
        {
            ViewState["sortexpression"] = e.SortExpression;

            if (ViewState["sortdirection"] == null)
            {
                ViewState["sortdirection"] = "asc";
            }
            else
            {
                if (ViewState["sortdirection"].ToString() == "asc")
                {
                    ViewState["sortdirection"] = "desc";
                }
                else
                {
                    ViewState["sortdirection"] = "asc";
                }
            }

            BindGrid();
        }
        protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)//对某一列进行隐藏显示，处理隐藏后不能读取数据操作
        {
            if ((e.Row.RowType == DataControlRowType.DataRow) || (e.Row.RowType == DataControlRowType.Header) || (e.Row.RowType == DataControlRowType.Footer))
            {
                e.Row.Cells[6].Visible = false;
            }

}
