A common scenario when using the ScheduleView control is to have custom appointments with additional properties that are not by default included in the standard Appointment class. In these cases simply extending the Appointment class is not enough, because we have some more requirements – we want our custom properties to support cancelation of editing (like the standard one does), we want to allow the user to edit the custom properties using the Appointment edit dialog and eventually to render values of the custom properties in the AppointmentItem or/and its ToolTip. In this article we will go through the following steps: Create a custom appointment...

This year’s European TechEd was a very interesting experience both for us – the guys at the Telerik booth, and for all of you that came to visit it and see what we have been doing lately. We were amazed by the variety of questions you had for us (showing that our whole product line is well-known and widely used) and therefore we would like to say a big Thank you!   One of the intriguing aspects of this year’s TechEd and our participation there was our new RadControls for Windows Phone 7 suite that was in its first CTP version by...

With this short post I’ll explain how to achieve a functionality similar to the one shown bellow. Unable to display content. Adobe Flash is required.   The key to achieving this scenario is to use Behaviors.

It has been a while since my last blog post on the topic but now that the Q3 2010 release is up and running, it is time to slow down a bit and restart my writing practice as well. The major highlight for the Data Visualization Team at Telerik for the past months was improving (enabling) the development of real-world business dashboard scenarios with the controls part of the RadControls suite.
