Repeater动态绑定数据

一、我的例子：（见SJTCMS/manage/report）

（1）效果图

（2）前台代码：

            
                
                <%#((DataRowView)Container.DataItem)["Colum"]%>
            
                
            
        

（3）后台代码：

/// 

    /// 绑定RptReport
    /// 
    /// 
    private void BindRptReport(string[] strClasses)
    {
        //如果没有选择栏目，则返回
        if (strClasses==null || string.IsNullOrEmpty(strClasses[0]))
        {
            return;
        }
        string strDepartmentId = SJTSoft.CMS.Global.Current.UserInfo.DepartmentId;
