Non-negative number required. Parameter name - length from Telerik.Web.UI.Upload.RequestParser.GetFieldBytes
PROBLEM
Sometimes a "Non-negative number required. Parameter name: length" error is thrown when the Obsolete RadUpload handlers are registered in the web.config file.
DESCRIPTION
Some data loss prevention software might interfere with the proper work of the application even though the RadUpload is not used on the specific page where the error is observed.
The full stack trace of the error is similar to the following:
Server Error in '/' Application.
Non-negative number required.
Parameter name: length
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.ArgumentOutOfRangeException: Non-negative number required.

SOLUTION
The solution is to remove the RadUpload related registration in the web.config as suggested in Mandatory Additions to the web.config. The support of the RadUpload is discontinued as of Q2 2012 - https://www.telerik.com/forums/important-support-for-radupload-is-discontinued. That is why we strongly recommend replacing the Obsolete RadUpload control with the new RadAsyncUpload one.
