    A bit of a mouthful on the title, sorry about that, but I want to make sure you get a slight idea of what I am trying to achieve.

    Ok, so a brief description.
    I have a RadUpload Control inside a AJAX ModalPopupExtender Panel. This works fine in IE 7, but in FireFox (version 3.0.7) the 'select' button will not work. All the other buttons do, but that one won't. In IE 7 though, it works fine.
    I haven't tested it in any other browsers yet.

    The other issue is to do with the RadUpload File validation. I checked for custom validation. The thing that keeps stopping me getting any further is the reference to Telerik.WebControls.
    I can not find any documentation anywhere telling me anything about this reference. If I go to 'Add Reference' I can see Telerik.WinControls, but no mention of WebControls anywhere. If I try to add the imports Telerik.WebControls, it just moans saying it can not find it.
    I need the import because without it I can not use ValidateFileEventArgs which is really what I need to use.
    Please can someone point me in the right direction. If you require a code example, I will put some in here.

    Telerik.WebControls is the old namespace for the obsolete RadControls for ASP.NET. I assume you're using RadControls for ASP.NET AJAX? You should be using the demos at So hopefully that helps with at least the demo portion of your question.

    Check out the following article for information on custom validation on RadUpload for ASP.NET AJAX:

    I'll let Telerik respond about the browser issue :)

    Hello JT,

    I have tried to reproduce the issue, however it is not showing up on my test project. Please find the project as an attachment. I will appreciate if you modify it, or send us a sample project that replicates the issue. Thus way we can investigate it further.

    Kind regards,

    The post is Jaymie/R3plica's, I was just helping with the misunderstanding the poster was having with the demos.
