    Showing RadToolTip on RadInput input error

    December 12, 2008 Share
    One of the tools in the RadControls for ASP.NET AJAX suite that is getting a lot of attention these days is the RadInput control. More specifically, the RadInputManager. With this "Manager" control, you can easily add validation to any textbox on your page without littering your markup with ASP.NET validator controls. Plus, you'll get a much more dynamic validation experience when you use RadInput instead of the OTB (Out of The Box) ASP.NET validation controls and better page performance (since the manager enables you to save a lot of HTML and JavaScript). One of the other features of the RadInput textboxes, including textboxes...

    Easily persist RadTabStrip Selected Tab using client-side API

    December 05, 2008 Share
    While working on a recent "real" project for Telerik, I used the RadTabStrip for ASP.NET AJAX to provide users with a list of content they could navigate. It was simple enough. A RadTabStrip with a few tabs, a RadMultiPage holding each tab's content, and content on each pageview that linked to new pages in the website. With very little effort, I had a rich, tabbed interface that worked completely cross browser. But then during beta testing, a tester reported a bug: if they navigated to a new page by clicking on content in the TabStrip, then clicked their browser's back button,...

    dotNetRegister: Requirements

    August 26, 2008 Share
    Before we can begin any serious coding of the recently introduced "dotNetRegister" reference app, we need to define some some requirements. As with any good agile development effort, I want to create a backlog of features that need to be implemented and then prioritize development from there. I even intend to work on this application in sprints, though clearly, as a part time project, I don't expect to have a stellar burn-down rate. ASIDE: If any of these agile terms- like backlog, sprint, or burn-down rate- are unfamiliar to you, I highly encourage you to spend a little time becoming more...

    dotNet Register: An Intro

    August 01, 2008 Share
    One of the tasks that has been on my "to do" list for quite some time now is to build a big, real world-ish application that not only provides value to the community but also shows-off a lot of the RadControls in action. It's a big task and one that's especially hard to tackle when traveling about the world to speak and preparing smaller demos that work well in "small bites." But I'm putting my foot down and committing to begin work on this big project now! The goal of my "big project"- which, by the way, still needs a...

    Optimization Tips: Optimizing Custom Skins

    Welcome back to my ongoing series on optimizing the Telerik RadControls for ASP.NET AJAX. For those that are counting, this is the fifth installment in the series, so if you've missed the first four parts I suggest you go back and read them now. This article builds on some of the concepts we've covered previously, so a sound understanding of the earlier concepts is a plus. And before you get confused, you won't find the other installments on blogs.telerik.com. Up to now, this series has been running on my popular Telerik Watch blog, but going forward all installments will be...
