    Windows Phone 7 MVVM #2 - RadJumpList

    After finishing the previous post, I realize something important – I would rather use RadJumpList than RadDataBoundListBox for my navigation in this application, simply because the “People Hub” type of experience is much cooler than a plain old listbox, regardless of how impressive the performance is.  We are also going to reconsider our MyItem and turn it into something a little more exciting – MyMVVMItem!  This will allow us to do add every new demo as an individual item, complete with a field for grouping, a friendly name, and a backing field for the name of the page that we...

    Windows Phone 7 MVVM #1 – RadDataBoundListBox

    Today we are going to be starting a fun new series that introduces you to the Model-View-ViewModel (MVVM) pattern with Windows Phone 7.  I am going to be using MVVM Light as my framework of choice, since it fits all my requirements and is amazingly easy to use, but if you want to check out another alternative feel free to tune into Bill Moore presenting on Windows Phone 7 and MVVM with Caliburn.Micro as part of our Windows Phone Wednesdays event.    The first step in this series involves doing two things – getting the latest and greatest copies of the Telerik...

    Creating Validation with RadDatePicker and RadWindow for WP7

    When allowing users to select a date value in your applications, one of the obvious issues is ensuring that they aren’t allowed to pick a value like December 24th, 563.  Thankfully, the developers for our Windows Phone team have incorporated some properties to help prevent this.  Step 1 – Min and Max Value Properties The easy way to make this happen is to simply set a MinValue and MaxValue.  In our scenario, we will say that we are scheduling appointments for some event in the future, therefore we can easily set out MinValue and MaxValue either via Xaml: <telerikInput:RadDatePicker x:Name="xRadDatePicker"                             Grid.Row="1"                             VerticalAlignment="Center"                             MinValue="5-6-2011"                             MaxValue="11-6-2011"/>   Or since we can’t hard-code a...

    Getting Started Video Series for RadTimeBar for Silverlight and WPF

    A week after the official release of RadTimeBar for Silverlight and WPF with the Q1 2011 SP1 release, we have some fresh new resources ready for you to watch to start getting the hang of working with RadTimeBar and integration with other RadControls. Last week I blogged about the Official Release of RadTimeBar, which included walking through some examples and some sample code.  But some of you would rather see it in action along with an expert voice on how this integration can take place - and we heard you!  We have just published three new videos up to Telerik TV...
