Memory Leaks and Memory Consumption in web applications (Part 1)
This post is number one in a three part series about memory consumption for web applications in general. Since the Web 2.0 era, Web Applications have changed for the better. They provide more functionality, better usability and improved performance. However this tendency led to increased complexity. It is not unusual for a user to stay on a single page for hours without leaving. The browser would just poll data from the server through Ajax requests and display it in even more interesting manners. Therefore it is no wonder that web applications have become hungrier for resources and the browsers couldn’t... -

Agile Seminar at the Great Indian Developer Summit
Joel and I did our “Agile Buffet Table” session at GIDS in Bengaluru, India. We talked about XP, Scrum, and Kanban and how you can build your own methodology by mixing and matching the features from each of these agile brands. We had *great* audience interaction, the best I have ever had in India. We wrapped up the session by opening Excel and designing a unique process with the audience. Our exit was also very funny, there was no break between sessions(!), so the next speakers came in and were ready to start when we ended. So I impersonated the next speaker, very agile. The slides are available here (via slideshare.) In... -

Performance Improvements in RadSlider
As Miro mentioned in his last post, with the upcoming 2011 Q1 Beta, we will release a new and improved version of RadSlider. A lot new features are being added and many of the existing hot spots were addressed along the way. One of them - the performance hit when RadSlider has to re-render its ticks. I took the liberty to compare the impact of RadSlider on an application before and after we made the improvements. Scenario: Every second, for 60 seconds, generate a new ViewModel and set it as DataContext to RadSlider. Goal: See how many times the LayoutUpdated event will... -

How to create Scatter Error Bars and Box Plot Series with RadChart for SL/WPF
Currently RadChart provides 27 2D Chart types for SL/WPF. You can easily customise the existing chart types to create a more complex series like the box plot(also known as box-and-whisker diagram and widely spread in descriptive statistics). This blog post will demonstrate how to create Box Plot and Scatter Error bars by reusing the default Styles of the CandleStick and Scatter series and adding custom CandleStick / CandleStickSeriesDefinition (ScatterPoint/ ScatterSeriesDefinition) pair of classes. Box Plot: The BoxPlot have five number summaries: the smallest observation (sample minimum), lower quartile(Q1), median (Q2), upper quartile(Q3), and largest observation (sample maximum).For the purpose the Open, Close, High and Low... -

RadControls for Windows Phone 7 Q1 2011 SP1 released
We are happy to announce the immediate availability of the first service pack for our RadControls for Windows Phone 7 tools. This is mainly a maintenance release with lots of bug fixes (more than 30), performance improvements and several small new features over the existing controls. We decided that we'd wait with the fresh new features and components that are being cooked in our labs until the first beta rather than ship them half-baked in an official release. Our toolkit is now even more stable and we are aiming high to make it as bug free as possible. A complete list... -

Official Release of RadTimeBar for Silverlight and WPF
When we rolled out the Q1 2011 release, there was a surprise control that we included in the release as a Beta version – RadTimeBar. This control is useful for scenarios where you require a birds-eye view of your time-based data, be it sales history, support volume, or any other statistic that you might want to track over a longer period of time. The real value in the RadTimeBar control, however, is in the integration scenarios that it offers with other controls from RadControls for Silverlight and WPF. By utilizing data-centric controls like RadGridView and RadChart with the RadTimeBar, your “birds-eye view”... -

RadControls for WinForms Q1 2011 Service Pack 1 is Out
Q1 2011 proved to be a successful release for RadControls for WinForms. With the introduction of the revamped RadTreeView and the new control RadWizard the Telerik WinForms suite continues on being the ultimate Windows Forms suite. Despite the fact that the new features are mature enough, they needed only a small finishing touch – a touch that your feedback made possible. It is our pleasure to announce the first Service Pack of Q1 2011 which finalized the recently introduced features and even added a few more. Among the highlights of the release are: • RadListControl now supports binding to business objects containing sub... -
