    Grouping & CheckBoxes in RadJumpList for Windows Phone 7

    By inheriting from RadDataBoundListBox, RadJumpList gets all the functionality that is normally introduced there. This is also the case with the support for the Check Boxes mode we recently introduced in RadDataBoundListBox. Basically, just as in RadDataBoundListBox, you can enable and activate the check mode in RadJumpList, check/uncheck items and also handle events that inform you when an item has been checked or unchecked. You also have access to the CheckedItems collection which can be used to programmatically check or uncheck items:     Now we have decided to extend this mode in RadJumpList since in the context of grouping items (what actually sets RadJumpList apart...

    Introducing Item Animation support for RadDataBoundListBox for WP7

    I bet that everyone using a Windows Phone have noticed the slick animations that are applied to a single item when it is removed or added to the viewport in the native mail client. That happens when you sync and the recent mail is added on top of the other items. Inspired by this, we decided to extend our RadDataBoundListBox and provide out-of-the-box support for per-item animations. Moreover, we made sure to allow customizations like defining your own animations, performing batch animations when resetting the source collection and defining a time interval between each separate animation when performing a batch operation. So...

    RadControls for Windows Phone 7 Mango and Q2 2011 (NoDo) SP1 are now available

    In mid-August, sometime after the Q2 2011 release, we upgraded RadControls for Windows Phone 7 to support Windows Phone 7.5 (Mango) and released an official build that contains some major performance improvements in RadDataBoundListBox and also all major controls that were introduced back then with Q2 2011: RadChart RadCalendar RadBusyIndicator Enough time has passed for us to gather some very valuable feedback from you to prepare a Service Pack which addresses some critical issues, introduces a new control (RadBulletGraph) and a meaty new feature in our powerful RadChart. We have also managed to greatly optimize the performance of our Data Engine by using the new System.Reflection.Emit APIs. RadChart alone represents...

    RadJumpList for Windows Phone extended: Support for Sticky Header

    Besides inheriting all performance improvements coming from RadDataBoundListBox RadJumpList further extends its functionality in our latest Mango Build with Sticky Header support. A sticky header is nothing more but a group header that is statically positioned at the top edge of RadJumpList’s viewport displaying the currently focused data group –just like in the revamped phonebook in Windows Phone Mango. This new functionality brings some small API extensions. There are now two new properties exposed by RadJumpList: IsStickyHeaderEnabled StickyHeaderTemplate The IsStickyHeaderEnabled property determines whether a sticky header is shown or not. This property is set to false by default. The StickyHeaderTemplate property can be used to specify a custom...

    RadDataBoundListBox goes Mango in terms of scrolling performance (video included)

      Back in the days when the first WP7 developer devices were distributed to all enthusiastic developers it became clear that the out-of-the-box scrolling performance delivered by the ListBox control from the toolbox is not satisfying at all. In fact, having some richer data templates and UI virtualization all in one made the control almost unusable which forced many developers to either give up UI virtualization or simply reduce the contents of their templates to boost the scrolling performance and thus improve the end-user experience. Although the Performance Team @ Microsoft have released some nice and helpful hints on how to...
