  AsyncFileUpload return always: "The file attached is invalid."

  Apr 16, 2010 07:42 AM|LINK

  Hi, I'm using vs2010, Framework4 and the related AjaxControlToolkit v4.0.30210

  Other controls works great such as the html editor, but the AsyncFileUpload return always "The file attached is invalid."

  How can I fix this?

  I found workaround: put <pages controlRenderingCompatibilityVersion="3.5" clientIDMode="AutoID"> in the web.config

  I tried <pages controlRenderingCompatibilityVersion="3.5" clientIDMode="AutoID"/>

  It worked, but it isn't compatible whit .netFramework 4.0.
  So use <pages controlRenderingCompatibilityVersion="4.0" clientIDMode="AutoID"/> to be compatible with 4.0

  
  

  Thanks for help me

  Self help's a wonderful thing :o) ... Thanks for the pointer.

  I found that setting the clientIdMode="AutoID" on the Async Upload Control itself also resolved it.

  And here is an older blog post with an example AsyncFileUpload tag using ClientIDMode="AutoID", in case you wanted an example in context.

  It's surprising what such a simple fix can do!
