  I am bulding a upload page, but I am confused as to the proper way to handle the contols. 
  I dragged the Asyncupload control into my area on my page.  When I do that it looks as though I also need to
  Add RadAjaxManager
  Add RadScriptManager
  Add RadStyleSheetManager
  Add ScriptManager
  
  When I put either of the the scriptManagers on the page I get an error that there is already a ScriptManager on the page.  And there is, it is used by the Tabstrip that I am using for navigation.
  
  I add the other two managers and they don't seem to do anything.
  I then add one of the Progress managers and it doesn't seem to do anything either.
  The last control I have is the Submit button for Postback, when pressed the screen goes blank and the file selected goes
  away with out any indication that an upload occured.  Since I am doing this all on my Laptop, where should I look for the uploaded file.

  Hi Stephan,
  
  The only things that the AsyncUpload control needs, are a ScriptManager to pe present on the page (doesn't matter if it's the regular one or RadScriptManager, but only one instance of it), and the registration of the Telerik.Web.UI.WebResource.axd in the web.config file. The options you see in the designer are just suggestions.
  
  When a postback of the page occurs, the file is set to the folder, specified by the TargetFolder property of the upload. You can also choose to save the file manually using the OnFileUploaded server event.
  
  You can read more about how to set up RadAsyncUpload in the following help article:
  http://www.telerik.com/help/aspnet-ajax/asyncupload-getting-started.html 
  
  You can also check out our live demos, which cover a lot of the different usages of the upload:

  All the best,
