It is often necessary to customize the header of a RadPane. Really common is to need to put an image in the header, to bind that image to a property, etc. There are many scenarios in which you need to add some custom behavior to the header.

The tricky thing here is that you need to implement an event handler for the Click event of the button and to write some code that will do something with the Pane. In...

We all are aware that users tend to look for the easiest and most rational way to do something. That is why developers always strive to create their products' interface as intuitive as possible.

The 'appearance' property does not affect the specified or computed values of any other properties.” A little bit of vague explanation, however it is not the point of my blog post. Using this WebKit feature in RadFormDecorator was crucial, and let us drop the listening to the poorly...

Hello everyone, and welcome to the second tutorial in my series of tutorials about the Telerik CAB Enabling Kit (TCEK). This week I will be talking about the UIExtensionSites supported in the TCEK.

In the last tutorial, we created ...
