GridView1排序

1.在GridView1添加AllowSorting="True" OnSorting="GridView1_Sorting"

2.在要排序的列加上SortExpression="Status"

3.

 /// <summary>
        /// 排序字段
        /// </summary>
        private string SortField
        {
            get
            {
                if (ViewState["SortField"] == null)
                {
                    ViewState["SortField"] = "Status";
                }
                return ViewState["SortField"].ToString();
            }
            set
            {
                ViewState["SortField"] = value;
            }
        }

 

//排序
        protected void GridView1_Sorting(object sender, GridViewSortEventArgs e)
        {
            SortField = e.SortExpression;
            string sortExp = GridView1.Attributes["SortExpression"];
            string sortModule = GridView1.Attributes["SortDirection"];
            if (!string.IsNullOrEmpty(sortExp))
            {
                GridView1.Attributes["SortExpression"] = SortField;
                if (sortExp == SortField)
                {
                    if (sortModule == "desc")
                    {
                        GridView1.Attributes["SortDirection"] = "asc";
                    }
                    else
                    {
                        GridView1.Attributes["SortDirection"] = "desc";
                    }
                }
            }
            //排序控制
            if (GridView1.Attributes["SortExpression"] == null)
            {
                GridView1.Attributes["SortExpression"] = SortField;
                GridView1.Attributes["SortDirection"] = "desc";
            }
            SetPageData();
        }

4.點擊列表排序時，取得排序字段和asc/desc

string orderSet = SortField + " " + GridView1.Attributes["SortDirection"];
