Changing Silverlight application themes at runtime

We have received a lot of questions how can the application theme be changed at run time. The most important thing here to mark is that each time the application theme is changed all the controls should be re-drawn. Without going into too much detail, we could explain the application themes as a mechanism to replace the content of the Generic.xaml file in every loaded Telerik assembly at runtime. This does not affect the controls that already have default style applied, hence the need to create new instances. Because in the Silverlight applications the RootVisual cannot be changed at run time, we...

Common reasons for the ‘Sys is undefined’ error in ASP.NET Ajax applications

In this blog I will try to summarize the most common reasons for getting the famous 'Sys is undefined' error when running an Ajax enabled web site or application (there are almost one million results on Google for that phrase). Where does it come from? In every Ajax web page’s source you will see a code like this: <script type="text/javascript"> //<![CDATA[ Sys.WebForms.PageRequestManager._initialize('ScriptManager1', document.getElementById('form1')); Sys.WebForms.PageRequestManager.getInstance()._updateControls([], [], [],...

Silverlight Recruiting Application Part 4 - Navigation and Modules

That way, as I start adding the functionality- adding Jobs and Applicants, Interview Scheduling, and finally a handy Dashboard- you'll see how everything is communicating back and forth. This is all leading up to an eventual webinar, in which I'll dive into this process and give a honest look at the current story for MVVM vs. Code-Behind applications. (For...

RadBook now supports virtualization

I am proud to announce that RadBook, along with RadGridView, RadTreeView, RadTreeListView, RadChart and RadScheduler, now supports virtualization. With previous versions, it would take up to 16 seconds to load 1000 pages, where now it takes just 2 seconds to load a set of 10,000,000 (10 million) items. The cause of the performance boost is the way RadBook handles the unnecessary(non-visible) elements. As you probably know, while turning a page, only four pages are visible at any given moment in time. Previous versions of RadBook would just collapse the unnecessary elements, which had a significant impact on the initial loading time. The...
