Happy Thursday to all you XAML-lovers out there! I'm back from the trenches with a new initiative aimed at teaching you how to use both new and existing controls from the Telerik RadControls for Silverlight and RadControls for WPF control suites. Starting today, every Thursday you'll be able to find a fresh batch of videos and sample projects highlighting a different control in a little series we're calling XAMLflix. The best part is that since we share a common codebase and API between our Silverlight and WPF suites you only have to learn how to use these controls once and can carry...

Since Q3 2011 we have changed the default drag API used. It allows creating more complex scenario as well as building MVVM friendly drag behaviors. However, it does not support drag arrow which, although not very popular feature is still used. Thus, when arrow was required, we have suggesting using legacy execution mechanism.

The arrow itself is located in Arrow...

RadMap provides a rich set of geocoordinate-enabled shapes that can be defined and displayed onto the map surface .There are scenarios, however, where you would like to do more than just position a shape onto the map.

For example we will select (highlight) a point, and drag the selected object to another location on the map – modifying in this way the shape or the line segment. First of all we’ll need two Information layers – one...

If you’re like me and you enjoy reading developer controls documentation (who doesn’t?), you may have noticed a new addition to the online documentation today for both RadControls for Silverlight and RadControls for WPF. It’s my pleasure to introduce you to a new effort we are launching alongside the Q3 2011 release – Telerik Patterns & Practices: Our first series for Telerik P&P is in direct response to a customer request, specifically for advice on how to handle an Event-to-Command scenario within their Silverlight application. Since there are more than a few ways to handle that we figured it would be...

Introduction JustDecompile is a new, free developer productivity tool designed to enable easy .NET assembly browsing and decompiling.
