How to set a file size limit on FileUpload Control

When uploading a file, I get the error - out of size exception

I've added the code below trying to get rid of it! - written in vb 

  dim filesize as string = FileUploadVal.PostedFile.ContentLength 
  If filesize > 1048576 then 
     des_label = "File is too large!"
  End if

But still getting the error, is there a way to set a file limit before uploading?

The file size would be greater then the allowed limit in web.config. You can set the HttpRuntimeSection.MaxRequestLength to limit the upload file size.

The MaxRequestLength property specifies the limit for the buffering threshold of the input stream. For example, this limit can be used to prevent denial of service attacks that are caused by users who post large files to the server, MSDN

<httpRuntime
   executionTimeout = "HH:MM:SS" 
   maxRequestLength = "number" 
   requestLengthDiskThreshold = "number" 
   useFullyQualifiedRedirectUrl = "[True|False]" 
   minFreeThreads = "number" 
   minLocalRequestFreeThreads = "number" 
   appRequestQueueLimit = "number"
   enableKernelOutputCache = "[True|False]" 
   enableVersionHeader = "[True|False]" 
   apartmentThreading = "[True|False]"
   requireRootedSaveAsPath = "[True|False]"
   enable = "[True|False]" 
   sendCacheControlHeader = "[True|False]" 
   shutdownTimeout = "HH:MM:SS"
   delayNotificationTimeout = "HH:MM:SS"
   waitChangeNotification = "number" 
   maxWaitChangeNotification = "number" 
   enableHeaderChecking = "[True|False]" 
/>
