ASPxGridView之Master-Detail

ASPxGridView之Master-Detail 参考页面官方demo：
http://demos.devexpress.com/ASPxGridViewDemos/MasterDetail/MasterDetail.aspx
Master-Detail能够使主表与子表的信息在同一页面展示，无须新建子表页面。
一直用一个grid,点击每行的详细按钮或链接，转到子表页面。今天尝试使用ASPxGridView中的Master-Detail完成了一个列表页面，下面是我的制作步骤及其经验总结:

1、在aspx页面上拖放2个控件。aspxgridview和ObjectDataSource，分别命名为grid和objSaleUser
2、为 ObjectDataSource添加数据源。

3、设置 grid的数据源为objSaleUser，设置KeyFieldName和AutoGenerateColumns="False"，添加你想显示的列。

设置SettingsDetail下的 ShowDetailRow="True"

4、 为grid编辑模板，选择DetailRow,光标定位于DetailRow，拖放一个aspxgridview进去，命名为detailGrid。




5、为detailGrid拖放一个ObjectDataSource到页面中，重命名为ObjSaleUserWeeklyReports
配置数据源和定义参数，因GetFinishedWeeklyReports中有一个实参saleUserID，所以在定义参数中为其设置一个 session。
6、设置detailGrid的数据源为ObjSaleUserWeeklyReports，设置KeyFieldName和 AutoGenerateColumns="False"，添加你想显示的列。设置SettingsDetail下的IsDetailGrid="true"

7、给detailGrid添加事件BeforePerformDataSelect，查看帮助文档知Occurs before the ASPxGridView control obtains data from a data source. When implementing a master-detail mode, the BeforePerformDataSelect
event should be handled to specify session values.在后台文件cs中为Session["saleUserID"]赋值。Session["saleUserID"] = (sender as ASPxGridView).GetMasterRowKeyValue();
8、前后台代码如下：
%@PageLanguage="C#"AutoEventWireup="true"CodeFile="SaleUserListReport.aspx.cs"
Inherits="Report_SaleUserListReport"%
