您需要在此处详细说明问题.是上传图片的问题，即保存在服务器上或在图片框中显示.

据我所知，没有直接的方法可以通过异步/部分回发模式上传图像.您正在使用Ajax吗?如果是，则图像将不会上传，直到您不刷新页面.

删除用于文件上传的Ajax或使用一些技巧将其上传.

You need to elaborate your problem here. Is it matter of uploading the image i.e. saving on server or Showing in Image box.

As I know there is no straight way to upload an image through asynchronous/partial post back mode. Are you using Ajax? If yes, then image will not upload until you will not refresh the page.

Remove Ajax for file uploading or use some trick to upload it.
