Error uploading large (> 2gb) file

[Michael]

We are uploading an unusually large file of 2.6gb using RadAsyncUpload but it appears to randomly stop (anywhere between 1 and 5%) with the following Javascript error

POST http://website.co.uk/Telerik.Web.UI.WebResource.axd?type=rau 500 Internal Server Error

Looking further into the error with Firefox shows the following details...

Post: {"TotalChunks":1229,"ChunkIndex":0,"TotalFileSize":2577377324,"UploadID":"1381758285922File.zip"}

So it looks like due to the file size in KB going over the limit for an Integer, the file is failing. Can anyone point me in the right direction of what to amend?

Many thanks

Hi Michael,

Earlier RadAsyncUpload had a size restriction of 2GB which has been resolved in the Q2 2013 release of Telerik RadControls for ASP.NET AJAX. In earlier versions the ContentLength property of the RadAsyncUpload was of type Int32 and hence you may receive errors such as 'Value was either too large or too small for an Int32' if you provide large values.
In this latest release the type of the ContentLength properties in the AsyncUpload is changed to Int64 and hence it is capable to handle files with size more than 2GB.

Thanks,
Shinu.

Thanks Shinu, we'll look at the options for us upgrading.

In the meantime I presume this control should be fine for anything less than 2gb?

Thanks,
Michael

Hi Michael,

You can use the RadAsyncUpload (applicable to versions prior to Q2 2013) control to upload files with file size up to 2GB. You can have a look into this documentation to check the necessary Web.config and IIS settings required to support large file uploading.

Thanks,
Shinu.
