    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...

    RadChart for Windows Phone 7 and Data Binding

    The fastest chart for windows phone 7 is just around the corner and it is not only fast, it is also very easy to use. To prove how easy to use RadChart is, consider the following steps which take the developer from a blank phone page to a page with a working chart that visualizes real data. In short the steps are these: Create chart object -> Add axes -> add series -> bind series to data. That’s right RadChart will support data binding on day -1 (this is the beta so it is not day 1 yet). Now let’s dig right into it. First...

    Building Windows Phone appointment viewer application

    {download the application complete source code from your Telerik account (register here for free if you are new to Telerik)} One of the great new features in the new Windows Phone OS, codenamed "Mango" is that developers have access to the device appointments. By using the new APIs we can now integrate the appointments in our applications. To make the developers' lives easier we created a new Calendar control that is an exact copy of the Metro calendar found in the OS. RadCalendar is "appointment-aware" in the sense that you can create a simple appointments data source and bind the calendar to it. This way, the appointments from the data source will be displayed in the month view like...

    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...

    Windows Phone 7 MVVM #4 - RadPhoneApplicationFrame and StateManager

    In our previous post we were able to utilize event triggers from System.Windows.Interactivity along with EventToCommand from MVVM Light to enable users to tap an item in our RadJumpList and then send a message out to perform some functionality – in our case, navigating to the page in question.  But where does this message go and how is it received?  And how can we add less than 8 lines of code to our application to give it a more native Window Phone look and feel as we’re navigating?  That’s what this blog post is all about! We will start with those...
