首先要给GridView设置三个属性
GridView4.AllowSorting = true; GridView4.Attributes.Add("SortExpression", "ENDDATE"); GridView4.Attributes.Add("SortDirection", "ASC");
然后写Sorting事件
/// <summary> /// GridView4的排序 /// </summary> /// <param name="sender"></param> /// <param name="e"></param> protected void GridView4_Sorting(object sender, GridViewSortEventArgs e) { // 从事件参数获取排序数据列 string sortExpression = e.SortExpression.ToString(); // 假定为排序方向为“顺序” string sortDirection = "ASC"; // “ASC”与事件参数获取到的排序方向进行比较,进行GridView排序方向参数的修改 if (sortExpression == this.GridView4.Attributes["SortExpression"]) { //获得下一次的排序状态 sortDirection = (this.GridView4.Attributes["SortDirection"].ToString() == sortDirection ? "DESC" : "ASC"); } // 重新设定GridView排序数据列及排序方向 this.GridView4.Attributes["SortExpression"] = sortExpression; this.GridView4.Attributes["SortDirection"] = sortDirection; //获取展示数据 DataTable table = SocketInfo.GetStatusInfo(sortExpression, sortDirection); GridView4.DataSource = table; GridView4.DataBind(); GridView4.Visible = true; }
