ASP.NET Extender Controls are cool. They allow you to add rich client capabilities to other server controls. The ASP.NET AJAX Control Toolkit is a wonderful example of unleashing the power of extenders to give regular ASP.NET server controls rich client capabilities. We tried this approach to further enrich RadGrid's otherwise quite solid set of client functionalities. The result is even richer. The sample project attached contains 2 custom extender controls that can be used with RadGrid. The two are similar in purpose, but different in usage. GridSliderToolTipExtender The GridSliderToolTipExtender is used with RadGrid's Slider pager. It provides you with a handy tooltip that is dynamically loaded over the RadSlider when you slide...

Writing state of art unit tests that can validate your every part of the framework is challenging and interesting at the same time; it's like becoming a samurai. One of the key concept in this is to keep our test synced all the time as underlying code changes and thus breaking them to the furthest unit as possible.

Task-It Series This post is part of a series of blog posts and videos about the Task-It (task management) application that I have been building with Silverlight 4 and Telerik's RadControls for Silverlight 4. For a full index of these resources, please go here. One of the posts listed in the index provides a full source download for the application, and I will be referring to that source code in this post. More about MVVM I recently received a comment on one of my blog posts about how the reader liked the strongly-typed property changed notification technique that I have in my Task-It, and it occurred to me that...

Using RadControls can boost the development process, using bunch of built-in features. However, sometimes we encountered scenarios where we need something very specific. In addition, we do want to make our custom logic encapsulated and easy reusable.  So,when this is the case,using behaviors is our best choice. In this blog I will show small example how to use the behavior power to enable row reorder functionality.     In order to enable drag and drop functionality, it simply uses our RadDragAndDropManager, giving us simple solution for the drag/drop functionality. So in order to use it and customize it we can even go the...

Animated cells on value changes   When dealing with streaming data which is updated over time the end user should be able to quickly track changes at a glance. A typical application that would benefit from this would be a financial dashboard, live data monitoring and tracking systems etc. For the purpose of illustration I have prepared a small simulation of streaming financial data (stock prices) .     In my previous blogpost I have already demonstrated how we can alter/extend the behavior of cells in RadGridView by placing a user control inside. This blog post demonstrates a more real-life and business oriented scenario. All...
