    Hi There -

    Is there any plan to implement a progress indicator for synchronous file uploads in the near future? (i.e. you submit the form and it displays how far you have got through uploading the files as part of the post to the handling action)  You have done it for the file upload for the asp.net RadControls I know as i have used that before.  I know synchronous uploads arent very fashionable these days but i dont really see that there is any better way of doing it when the user is uploading very large files (up to 1GB) as you dont want them to have to wait literally half an hour for the asynchronous upload to complete before they are able to submit the rest of the form - they just need to be able fill the form in, attach the file, click submit and let it run (with a progress bar to show how far through it has got - hence my request!)

    Thanks

    Hello,

    The progress tracking in RadControls works by means of an HttpModule. It intercepts the requests and provides progress information via polling.

    The approach is sound in theory, but the reality is different. The module is different to maintain due to its heavy use of reflection. Network latency means that the results are not exactly accurate. In addition, its hard to configure and prone to compatibility issues with other modules.

    Given these drawbacks we prefer not to have this feature in the MVC suite. The benefits it provides are marginal compared to the cost.

    Apologies for the caused inconvenience.
