Hi,
How can I trap/catch an unknown upload failure on client side and display custom error message/feedback to the user?
I'm using RadUpload And RadProgressArea controls. I display progress bars.
I don't have exact error details, but I remember when an upload failed, a huge javascript alert box was displayed with all technical jargons.
I want to catch that and display custom/user-friendly error message to user.
We can assume we are talking about timeout. I know I can set the maxrequestlength and session time limit in web config.
Thanks,
Chirag

Hi chirag,
Unfortunately currently RadUpload does not provide such a possibility. As this seems a nice feature, we will include it for the next official release. Please, open a formal support ticket if you would need an intermittent build and instructions.

Hi Erjan,
Do you expect that the update will be able to handle the 404 error when an upload file is larger than the maxrequestlength?

Hi,
Unfortunately the answer is "no". The Max File Size Exceeded (and the Page Not Found error respectively) is thrown at a higher level of the ASP.NET Operation. To my regret RadUpload cannot handle that.

Just curious how are other users handling upload errors when file exceeds maxrequestlength. I can't find a way to let users know that they are uploading a file that's larger than allowed.
Please advise on how you're talking care of this issue. Thanks.

Hi Scott,
There are two possible approaches.
The first one is just informative - add a label around the RadUpload instance, which will display the maximum allowed size.
The other approach is to use the client-side file size checking approach. Please note, that the latter depends on the asynchronous progress update Ajax calls and some the data gets uploaded before the client-side event is triggered. That means that on localhost validation might not occur if uploading relatively small files (e.g. <5MB).
You can use both the approaches to make best client experience.
I hope that helps.

I have that label, but some users don't read it or ignore it. So, they upload a much bigger size, how do I show a friendly error page or message? When they upload a bigger size than maxrequestlength, it won't even attempt to upload, it simply errors out immediately.

Hi Scott Rupp,
I am afraid we cannot do anything in this case to prevent that error.
