    RadTreeView for ASP.NET Ajax Load On Demand Modes - why so many?

    In my previous blog post I told you how the Web Service load on demand mode of RadTreeView delivers the best performance. A logical question arises - why we have the other load on demand modes (server side postback and callback) if they do not perform on par with the Web Service mode. The answer is not that obvious. The truth is every load on demand mode has its pros and cons. The following table describes visually the load on demand modes according to three criterions - performance, templates support, ease of...

    Best Practices: Client-Side DataBinding with the RadGrid for ASP.NET AJAX

    I recently released the first two episodes of my new screencast series, RadTips. In these episodes I show users how to take advantage of the new client-side databinding feature of the RadGrid (only available in the Q2 2008 release of RadControls for ASP.NET). I wanted to highlight what we consider to be a best practice when using the RadGrid's client-side API to do your databinding, something I didn't do in either of the episodes. While client-side databinding can save some bandwidth and improve round-trip speeds on subsequent requests, it is actually faster to to bind data to the RadGrid on the...

    Performance Tip: Use Web Service Load On Demand with RadTreeView

    A common scenario for a treeview control is to populate it with lots of nodes. Adding a few thousand nodes initially is not a good idea though. Think of all the rendered HTML. Even rendering a few thousand strings (without any extra markup) will result in a few megabytes of HTML. That's where load on demand comes into play. RadTreeView supports three different types of load on demand: web service, server side callback and server side postback. From those the server-side postback mode is least efficient in terms of performance because it postbacks and updates the whole page. Here is how...

    How To: Color Picker done with few slider controls

    This tutorial demonstrates how to create a color picker using nothing more than few elements and Telerik's slider control for Silverlight. To start off, create a new Silverlight project. It is up to you to decide whether you want a web page in the project or not. This particular example does not to include a web page, but a simple html page that is generated dynamically. Once you have the project created go ahead and add a reference to the Telerik.Windows.Controls.dll. At the top of your main UserControl, add a namespace in order to use the dll. Check if everything...

    RadTips, Episode 2: Client-Side Paging in the RadGrid

    Here for your viewing pleasure is the second episode in my new series, RadTips. In this episode I show you how to implement paging in the RadGrid when binding data to the grid on the client. This is an important feature to know because it must be implemented on the client if that is where databinding occurs. As always, your comments are welcome. Please bear with me as I get the hang of screencasting, but don't hesitate to offer your feedback if you'd like to suggest how I can improve the shows. Also, if the size of the embedded video is...
