添加操作事件以进行updatepanel同步或异步

add the action events for updatepanel sync or async

众所周知，文件上载"不能与更新面板"异步工作.您需要完整的回发.因此，可以将FileUpload放在UpdatePanel外部，也可以在Update Panel中为FileUpload控件定义回发触发器，例如: AjaxToolkit:AsyncFileUpload演示 [ AsyncFileUpload控件-Ajax控件工具包中的新控件 [ ^ ]

It is a known thing that File Upload does not work async with Update Panel. You need to have a complete postback for it. So, either place your FileUpload outside UpdatePanel OR have a Postback Trigger defined for FileUpload control in Update Panel, example: Using FileUpload Control inside ASP.Net AJAX UpdatePanel Control[^]


In case you want upload to be async, Microsoft released a new control that can be used:
