You saw from the previous step that you can configure Entity Data Source or other server controls in Design mode but at the end, only few lines added in the Mark up.So why bother figuring out how and what to select in design mode while you can hard code exactly what you want your control to do, in the mark up? Data Item 当前行绑定的对象 如果要在Item Data Bound 事件中对Item Template模板中的控件做处理,则必须使用runat=server的控件为控件设置ID,然后用 Find Control根据ID来取得控件 在 Data List 中生成事件时激发,当用户点击按钮后激发可以在模板中放置Button控件,模板中的按钮一般不写On Click事件,而是响应Repeater的Item Data Bound事件为Button控件设定Command Name, Command Argument属性,然后在Item Data Bound事件读取e的Command Name, Command Argument属性就可以获得发生事件的命令和参数了,如果对数据进行操作,则需要 Repeater1.
