RadJumpList for WP7: Part III - Performance with large data
Download the sample project In the previous two posts I explained the e basic usage and the support for dynamic sorting/filtering and grouping in RadJumpList. Now it is time(1) to see how the control behaves with large data sets. It is unlikely that in an average Windows Phone 7 application you will need to show more that 1,000-2,000 items, but we decided to test the performance under extreme conditions with a large set of 10,000 items. The setup of the example is pretty simple - we are generating 5k items on the fly and them bind the JumpList control to the data set. In the sample you can... -

RadJumpList for WP7: Part II - Dynamic Sort, Filter and Group
Download the sample code of the example. In my previous post I explained the basic usage of the RadJumpList control and how to display the data by using declarative sort and group descriptors. Now in part two you will see how to give your users the ability to modify the sorting, grouping and filtering on the fly. There is no out of the box UI for these data operations provided in this version of the control. We are still not sure what will be the preferred way of implementing this from a UX perspective and how to align it with the Metro guidelines. So for the moment we... -

It is a fundamental control for building data driven WP7 applications. We invested a lot into our data engine story - we have our own internal CollectionViewSource implementation which allows you to sort, filter and group your data with a single line of code (more on the data engine in this in-depth blog post). Apart from the data engine we also built a high performance ListBox control. RadDataBoundListBox is a virtualized ListBox control which has two major features: can display... -

Grouping, sorting and filtering for Windows Phone 7 – what the options are?
One of the most useful controls in Windows Phone 7 is the so called “JumpList” and its popup “Quick Jump Grid” UI – that is, according to the official Microsoft design guidelines, a “Way to help the user to scroll through long lists”. The First Look example of RadJumpList in our demo application Much like in Windows 7, the “quick jump grid” user experience enables you with fast navigation to a desired location within the associated list of items. In order to populate the jump grid with items, the underlying list should be grouped by some criteria. So, how do we... -

Online demo for Windows Phone 7 Gauges
Last week we officially published our first Beta release of the Rad Controls for Windows Phone 7. One of the major new components in this Beta release is our first data visualization entry - RadGauge. You can read more info about RadGauge in the announcement blog post. What we did right after the beta release is to make sure that RadGauge can be seen online - hosted in-browser. As you know the WP7 platform is based on the Silverlight 3 framework and this means that with very little changes we can show our WP7 controls hosted inside the browser. This is what we did -...
