    Formatting RadChart Labels

    Hi everyone, My name is Vesselin Georgiev and I am a technical consultant here at Telerik. This is my first blog post and it is dedicated to labels in RadChart. By default RadChart will display the value corresponding to the bar (point, slice) as a label.  But RadChart allows you to control the label content. This is possible thanks to the DefaultLabelValue property, which has been around for quite some time now. You can use several “special words” in this property -- "#Y", "#X", “#%”, “#SUM”, “#STSUM”, “#SERIES”, “#ITEM”. They are all listed in the dedicated help topic . This is all good, but...

    Opera 9.5 - Love at First Sight

    The new Opera 9.5, released about a week ago, quite easily established itself as my default "home" browser. It is sooooo much faster than Firefox and Internet Explorer, especially when it comes to heavy web applications such as Gmail and Facebook (and doesn't hang either). And what's more, the Opera guys finally made the Alt + D keyboard shortcut focus the address bar as is in the other two browsers (stretching out to reach F8 was rather inconvenient. Happiness is in the small things, you know... :-) ). Opera 9.5 also includes DragonFly, which is the more powerful successor of the browser's...

    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...

    Firefox 3

    Today is D-Day ("Download Day") for the much-anticipated version 3 of Mozilla's popular web browsing client, Firefox. In an effort to create more buzz around the launch, Mozilla has requested that users help them attempt a new Guinness World Record for most downloads in a 24-hour period by downloading the new Firefox release today. Over 1.7 million people from around the world pledged to download the new client today. As an aside, I think its pretty cool that they are trying to get in the Guinness record books, but is it really a record if it's never been done before? I...

    How To Override Styles in a RadControl for ASP.NET AJAX' Embedded Skin

    In the era of the "classic" RadControls for ASP.NET modifying a skin required opening ~ / RadControls / [ControlName] / Skins / [SkinName] / styles.css and making the necessary changes. The new RadControls for ASP.NET AJAX (formerly known as "Prometheus") by default use skins, which are embedded in the assembly. This simplifies deployment but sacrifices customization. Or does it? Actually, making a change to an embedded skin of a RadControl for ASP.NET AJAX is quite easy, given that one keeps in mind a couple of notable things. Namely: (1) Since the embedded skin cannot be modified, the custom styles need to be placed elsewhere. For example ...
