    Uploading Multiple Files with RadUpload

    Hello Everyone, my name is Rosi and I am a developer on the ASP.NET navigation controls team. This is my first blog post and I will be talking about the RadUpload component.  Many customers have asked how to upload multiple files with it. Unfortunately RadUpload does not yet support this functionality out of the box, but I will show you how to work-around this limitation. The trick is uploading one  .zip file and extracting it on the server.  To achieve this we will need a little help from a third party library.  Such libraries are  DotNetZip and SharpZipLib which provide a convenient API to manipulate .zip files.  For the purposes of this blog post...

    Introducing: the telePhone

    After digging around in Telerik's old Visual Source-Safe server, I found a long-forgotten prototype of a RadMenu skin. I felt the urge to disclose it to you, and hope that you will like it. the telePhone prototype On second thought, this initial draft looks good enough, so we might switch to hardware production. Don't be evil, we were first! Maybe we could even go 3G... Ok now, getting serious - you could use this sort of menu for navigating when there is a large hierarchy in the site navigation (or, to be more specific, a hierarchy that has a wide tree). Currently, no...

    RadControls for ASP.NET Ajax and IronPython

    We recently received a request if RadControls for ASP.NET Ajax support IronPython and the answer is “yes”.
