AsyncUpload can't access addtional field on server side, always return null value

[David]

I tried to put AsyncUpload into one of my usercontrols, but I always  got null exception error when I tried to get addtional field at code behind. At first I thought that's user control's problem, but  later on, even I put the exact the same code as demo into my test page, I got the same null exception error  on this line :

<%#((Telerik.Web.UI.UploadedFile)Container.DataItem).GetFieldValue("TextBox").ToString()%>

Anyone else got same issue as I got? Pls take a look whenever you have time, really appreciate.

anyone has a solution for this?

[David]

hi Guys, the problem has been solved.. That's my mistake, I should use the newest telerik.web.UI.dll to replace the previous one.. 

What a stupid mistake I made... pls close the post. 

Thanks.

Hello David,

We had some issues with the Additional fields demo. Please take a look at the attached example. The demo will be working correct in all cases for the next service pack.

Best wishes,
