    RadDateSelector for Windows Phone 7 – Loaded within a standard in-browser Silverlight application.

    Silverlight for Windows Phone 7 is version 3.7 hence a WP7 control should be easily used within a standard Silverlight 4 application. But that’s in theory. The major differences between these two worlds are the so called “Manipulation” events. Each UIElement in WP7’s Silverlight is “enabled” with the following routed events: ManipulationStarted ManipulationDelta ManipulationCompleted  Generally this sequence of events encapsulates one or more touch gestures in a transaction block. The event arguments carry all the information needed to determine what the gesture is and what effect to generate. And of course RadControl for WP7 use these events extensively in order to provide consistent and rich...

    RadLoopingPanel – a look inside (or why Telerik’s RadDatePicker is the fastest date picker tool for Windows Phone 7)

    Everything in Windows Phone 7 is Content and Motion. Both of these key Metro parts are combined with a blazing fast performance and unmatched responsiveness throughout the entire OS. Same must be true for all custom applications – no room for performance compromises. And that is why one of the major focuses of the entire development process of RadControls for WP7 is performance. We are even ready to delay some features for a next release for the sake of being feather-light and as fast as possible. As I explained in this blog post, from the very beginning we tried to reuse the...

    Building a Windows Phone 7 control from the ground up - Part Two - the “Date ListBox”

    The next interesting part of building a Windows Phone 7 DatePicker control is the Date ListBox. That is a ListBox which should meet the following requirements: Can display in a human readable manner one of the three Date components: Day, Month and Year Should be “Infinite” – as discussed in my previous post. Should use data virtualization (to be most efficient). As you can see our “Infinite ListBox” project now comes in hand. The last two of the upper requirements are already implemented and all we need to do is to implement a special VirtualizedDataItem<DateTime> that provides the needed information to bind to. For a...

    Building a Windows Phone 7 control from the ground up - Part one - the “Infinite ListBox”

    One of the coolest things in every new developer platform is the challenge to master the entire framework in a way that enables you to create high quality, greatly optimized controls that behave in exactly the same way a user would expect to. Yesterday Microsoft announced that more than 300 000 developers have already downloaded the WP7 Developer Tools Beta. Based entirely on Silverlight, phone development has never been easier and more fun than in the Windows Phone 7 environment. With these series of blogs I want to reveal some tricky moments in developing a simple DatePicker control for WP7....
