    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...

    Fun with RadLoopingList: Horizontal looping

    With RadControls for Windows Phone 7 Q2 2011 Beta 2 we have extended the feature set of RadLoopingList by adding support for horizontal looping: there is now a new Orientation property which can be set to either Vertical or Horizontal. We have also prepared a nice example in our Telerik Demos app (available on the WP7 Marketplace) which uses RadLoopingList to build a picture gallery that shows gallery items in a movie strip: Since some of you asked us to explain how this example was built, I decided to put it in a blog by giving all the steps you need...

    RadDataBoundListBox for WP7 matures, now adds Multiple Items Selection support

    Q2 2011 Beta 2 of RadControls for Windows Phone 7 is on its way and part of the box is a meaty new RadDataBoundListBox feature: multiple items selection ability. As many of you already know, the mail client on all Windows Phones shows a check box next to each visual container thus allowing the end-user to select a bunch of items and perform an action with them. RadDataBoundListBox can now do pretty much the same thing by exposing a very convenient API and neat UX for working with checkboxes. There is now a CheckedItems collection which exposes methods for checking/unchecking items programmatically,...

    Implementing Data Paging with RadDataBoundListBox and the OnDemandManual Data Virtualization Mode

    It is clear that a good data driven Windows Phone 7 application must have a smart approach of handling large amounts of data and keeping jagged scrolling and long lasting loading screens away from the end-users. There are a bunch of approaches which handle similar situations but recently I had a discussion with a developer using our controls which focused on implementing data paging as a way of coping with large amounts of data. During this discussion I came up with an idea to utilize the OnDemandManual data virtualization mode of our RadDataBoundListBox to implement a mechanism which loads pages of...

    RadDataBoundListBox learns new Data Virtualization techniques

    RadControls for Windows Phone 7 Q2 2011 Beta 1 is already at the doorstep which means that you will be able to have a hands-on experience with everything we have been working on lately. A significant piece of the cake are the new data virtualization capabilities that RadDataBoundListBox adds to its repertoir. We have already announced some of the bits in an earlier blog post and now it is time to reveal the bigger picture of what you will be able to do with this control after the new release. So, we will be adding two more virtualization modes that will provide the same...
