使用Ajax进行文件上传控制 [英] fileupload control with ajax

问题描述

我正在aspx页面中使用ajax选项卡控件.
在该控件中，我正在使用fileupload控件上传图像.
但是fileupload控件无法获取任何文件.

I am using ajax tab control in aspx page.
In that control i am using fileupload control to upload the image.
but fileupload control is not able to get any file.

if(fileupload1.hasfile==true)
{
string f=filupload1.filename.tostiring();
string fpath="~/image/image/"+f;
fileupload1.saveas(mappath(fpath));

所以在if条件下会出现错误.

推荐答案

您不能直接在更新面板中使用文件上载控件上载文件.

请参阅此处的链接.

或者您可以使用一些第三方api.

You can''t upload file with file upload control in update panel directly.

refer the links here.

or you can use some third party api.

文件上传将需要完整的回发.

试试:
回传更新面板的触发器

File upload will need full postback to work on.

Try:
Post back trigger for the update panel

<asp:PostBackTrigger ControlID="fileupload1" />
