功能:
- 单击行弹出当前行详细页面
- 双击行进入编辑状态(GridView/DataGrid内置 Edit)
说明:
- 单击事件(onclick)使用了 setTimeout 延迟,根据实际需要修改延迟时间
- 常见处理行方式会选择在 RowDataBound/ItemDataBound 中处理,这里我选择 Page.Render 中处理,至少基于以下考虑
- RowDataBound 仅仅在调用 DataBind 之后才会触发,回发通过 ViewState 创建空件不触发 假如需要更多的处理,你需要分开部分逻辑到 RowCreated 等事件中
- 并且我们希望使用 ClientScript.GetPostBackEventReference 和 ClientScript.RegisterForEventValidation 方法 进行安全脚本的注册,而后者需要在页的 Render 阶段中才能处理
- 关于“DataGrid中采取的辅助按钮支持回发”见ASP.NET DEMO8: 为 GridView 每行添加服务器事件
- PS:未实现 Edit 对应的 Update/Cancel ,根据需要自行添加即可。
原始需求:既有单击又有双击的GridView是否存在(问了许多人都说不能,郁闷)
