UpdatePanel中的文件上传控件 [英] fileupload control in UpdatePanel

问题描述

大家好，

您能否让我知道UpdatePanel中fileupload控件的用途是什么，因为通常FileUpload控件无法在UpdatePanel中完成部分回发，因此需要完整回发.

因此，为了使这项工作有效，我们使用了回发触发器，我想知道通过使用此触发器将整个页面都发回还是不发回.

如果不是，则在UpdatePanel中使用fileupload控件很有用.

如果没有，请您解释一下如何在不使用Ajaxtoolkit控件的情况下实现部分回发.

谢谢.

Hi All,

Can you please let me know what is the use of fileupload control in UpdatePanel because normally FileUpload control does not work with partial postback which is done in UpdatePanel and it requires a full postback.

So in order to make this work we use Postback trigger and i would like to know by using this will the whole page be postedback or not.

If no, then using fileupload control in UpdatePanel is useful.

If no, can u please explain how can i achieve partial postback without using Ajaxtoolkit controls.

Thanks.

Prathap.

推荐答案

u必须使用触发器，在触发器u中可以分配controlID和eventname
< trigger>< asp:asynprocess controlid =" eventname =" xmlns:asp =#unknown">

u have to use triggers,in trigger u can assign controlID and eventname
<trigger><asp:asynprocess controlid="" eventname="" xmlns:asp="#unknown">
