Desktop: WPF

  With this post I’ll show you how to create a simple catalog like functionality for your application using RadTileView and RadDataPager.  We will create a catalog with 10 000 RadTileViewItems distributed in 100 pages and each page will have UI Virtualization. At the end this sample application will look like this: Demo We’ll start with a tileview, a datapager <Grid x:Name="LayoutRoot" Background="White">     <Grid.RowDefinitions>         <RowDefinition />         <RowDefinition Height="Auto" />     </Grid.RowDefinitions>       <telerik:RadTileView x:Name="myTileView" />     <telerik:RadDataPager Grid.Row="1" /> </Grid> … and a simple business item...

The Q1 2011 version of the Chart control will include code to support empty/null values. There are many scenarios, in which the property of an object, or a collection of objects, to which the Chart is data bound, is null. The following code example demonstrates one such case: The null values above are hard-coded, however they convey the general idea of null values being returned by the data layer, to which the Chart is data bound. Internally, there are three ways in which these null values can be handled. This is specified by a property in the control, for the series...

These are controls that exist in one form or another in most of the other suites so we had some client requests to add them in our Silverlight / WPF suite too. In WPF you have GroupBox, Label and ToolTip in the presentation framework however we had no themes for them. In Silverlight there is only ToolTip. GroupBox and Label We have created GroupBox and Label in Telerik.Windows.Controls assembly. In WPF they extend the existing GroupBox and Label controls and only add themes. In Silverlight they extend HeaderedContentControl and ContentControl. How you can use them: <Grid x:Name="LayoutRoot" Background="#FF222222">     <telerik:GroupBox Header="Personal Information" Width="300" HorizontalAlignment="Center" VerticalAlignment="Center">         <Grid>             <Grid.ColumnDefinitions>                 <ColumnDefinition Width="Auto" MinWidth="80" />                 <ColumnDefinition Width="*" />...

With the Q1 2011 release just being around the corner a new and amazing version of RadTileView will be available. It is sleek, fast and more responsive than ever and it brings a whole set of new features and functionality to the table. Download and play with the new bits . Virtualization The main feature, that I’m sure you’d like most is the UI Virtualization (delaying the creation of UI Elements). We implemented it in both tiling scenarios: Restored – this includes both directions - Horizontal and Vertical . It means that if you have 10 columns x 1000 rows you'll get 10 000 tiles and you’ll see both scrollbars....

There are times when we run into a scenario in which we need point selection on a chart.  Luckily, RadChart for WPF and Silverlight already has this feature - but what if you need to find the closest point to where you selected on a chart?  And what if you have multiple chart series that you are doing this with?  Normally, this would be a bit of a challenge as this involves figuring out where the user clicked, what is around it, etc. Luckily for us, we have charting wizards like Manol Donev on our team and an aggressive release cycle here at Telerik.
