ASP.NET control with MVC's Razor engine -

I am using ASP.NET MVC 3 with the razor template engine for my website. I currently allow uploading files like this:

   & Lt; Input type = "submit" name = "submit" value = "submit" /> & Lt; / Form & gt;   
 But a third party control, such as, which allows a progress bar, multi file selection, etc.  
 In the document, they show control as being used in this way:  
  & lt;% @ Register TagPrefix = "Upload" namespace = "Brattle. Web.natuploads "assembly =" braille web.nettypeload "%" & Lt; Upload: Input file id = "inputFileId" runat = "server" /> Some code-behind   
  
 Razor engine does not like this syntax. Is there another way to use third party control, or am I out of luck?   
 
 
 Controls that work with third party web forms are actually  net  MVC After saying this, you can work with a hybrid solution, take advantage of web forms in some places and use MVC in others. It's not something I personally do, but you can do it  
 Look at Scott Hanselman who goes to some details about doing something.  
 Using the web form control on the razor page however will not work though.
