    Q3 2011 SP1 RadJumpList for Windows Phone 7 now adds support for bindable Data Descriptor collections

    January 05, 2012 Share
    Some time ago a customer of ours asked us if there is a possibility to use the FilterDescriptors, SortDescriptors and GroupDescriptors collection in a MVVM context by binding them to collections defined by the view model. As all the data is managed there, why not also manage the data operations in the same class? Unfortunately, these three properties are readonly and therefore binding them to a property defined by the main view model wouldn’t work. We decided that allowing similar scenarios will simplify the development with RadJumpList and therefore as of Q3 2011 SP1 the control exposes three new properties which...

    RadDate- & RadTimePicker for Windows Phone 7 extended to support custom selector intervals

    December 22, 2011 Share
    It is a common scenario when we would like to limit the selectable values in a time or date picker control. Normally we would do this by setting an allowed date-time range but a more sophisticated case is when we also want to filter out some selection possibilities and allow only specific ones. Imagine an application that provides the end-user with the possibility to create reminders that can only happen in time intervals of 15 minutes: 3:00 AM, 3:15 AM, 3:30 AM... Here we don’t want to prevent the user from selecting values from the whole time-range, but want to make some...

    One of the new controls that come in the Q3 2011 package is RadAutoCompleteBox: an extended TextBox control that provides a flexible infrastructure for displaying suggestions to the user as they type. Coming with a bunch of customization options, RadAutoCompleteBox implements two auto-complete strategies that cover the most common developer scenarios: Contains filtering mode StartsWith filtering mode Here is a screenshot of our new Auto Complete Box example in the Telerik Demos application: Both the Contains and StartsWith filtering strategies are implemented in a very performance oriented approach and are capable of handling large data sets by preserving the smooth and responsive UI experience. Besides all that, RadAutoCompleteBox...

    Fun with RadLoopingList: Creating a Numeric Picker with RadLoopingList - Introduction

    November 08, 2011 Share
    A few weeks ago we received a support ticket from a customer using RadControls for Windows Phone 7 who wanted to use RadLoopingList to create a control that will allow the end-user to pick numbers in the range 0.00 – 99.99. The requirement was that each decimal position should be represented by a looping list allowing for selection between all digits from 0 to 9. We managed to quickly set up a small WP7 project that demonstrates how this can be done with RadLoopingList and helped our customer in creating a control that looks this way:     Since this scenario could prove useful...

    Grouping & CheckBoxes in RadJumpList for Windows Phone 7

    October 28, 2011 Share
    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...
