DataGride排序小结

DataGride排序

首先拖入DataGride控件

现在前台拖入隐含控件<INPUT id="sortfield" type="hidden" value="UserID desc" name="sortfield" runat="server">

设定排序字段

然后再启用SortCommand事件

//排序
privatevoid Dg_Directory_SortCommand(object source, System.Web.UI.WebControls.DataGridSortCommandEventArgs e)
        {
            CommMethod.DataGridSort(e.SortExpression, sortfield);
            this.sortval.Value = e.SortExpression;
            GetData(Page1.NowPage);        //绑定数据
        }

调用排序方法

///<summary>
        /// 对DataGrid进行排序
        ///</summary>
        ///<param name="p_Exp">排序表达式</param>
        ///<param name="p_SortField"></param>
publicstaticvoid DataGridSort(string p_SortExp, HtmlInputHidden p_SortField)
        {
            if (p_SortField.Value.EndsWith("desc") ==false)
            {
                p_SortField.Value = p_SortExp +" desc";
            }
            else
            {
                p_SortField.Value = p_SortExp +" asc";
            }
        }
