    Don't Use BODY ONLOAD in ASP.NET AJAX Websites

    In the past developers used <body onload="..."> to execute some script as soon as the page is loaded. Nowadays this is rather old-fashioned, no matter how you look at it. What's more, it doesn't work as expected in ASP.NET AJAX websites. Consider the following example:   <body onload="MyFunction()">    <script type="text/javascript">       function MyFunction()     {        var myAjaxControl = $find("myAjaxControlClientID");        myAjaxControl.doSomething();     }    </script>    </body>    The client-side page load event is fired by the browser as soon as all HTML and scripts have been loaded. However, this happens before the controls' client-side instances have been created. As a result, myAjaxControl will be null and the doSomething() method will trigger a Javascript error. So, a lot better approach...

    Showing RadToolTip on RadInput input error

    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...

    Make your applications look like Office 2007 with the RadRibbonBar

    The ribbon bar was first introduced with the release of Microsoft Office 2007.  It resides across the top of a window and is the primary means of accessing application functionality.  Unlike the classic menu toolbar approach the ribbon bar offers the ability to display functions and commands in an way that you can locate what you need more quickly.  This is in large part due to the context sensitive way that functionality is displayed.  The ribbon bar is a great usability improvement to most applications since functionality is not buried beneath a multitude of hierarchical menus and toolbars.  Microsoft has...

    IMS London 2008 – First European Thrills for Sitefinity

    … And surely not the last ones! This massive event on content management and Web 2.0 technologies gave us the chance to see the way a conference goes in Europe. We were definitely not disappointed – the event was huge, all of the usual suspects were there of course :) It turned to be a very interesting experience – our staff at the booth quickly learned that the approach here should be different – the audience primarily consisted of business users who were not exactly into coding; the attendees seemed to be more reserved and shy when approaching the exhibitors;...

    Getting Started with ADO.NET Data Services and Telerik Open Access - The First step

    To my opinion the day the Astoria incubation project was unveiled,  all about querying and pushing data through a webservice changed for good. I was pretty amazed to see that the REST paradigm was so easily embraced in the .NET world. Now some time later, this is an official release and it is called ADO.NET Data Services. For all of you that are not familiar with ADO.NET Data Services you can find more information here. To put it shortly: <quote>“The goal of the ADO.Net Data Services framework is to facilitate the creation of flexible data services that are naturally integrated with...
