    RadChart for SL/WPF: Data grouping and aggregation

    Howdy folks! The RadControls for XAML Q3 Beta1 is out and it features an updated version of the RadChart control. We receive dozens of feature requests every day and one of the more substantial ones is the ability to analyze data with RadChart. The feature I will describe today is a great step in that direction. I’m talking of course about data grouping and aggregation.   Just like grouping and aggregate functions are one of the major features of our GridView control they can be used with the charts as well (if you have the beta). Basically the feature allows you to group business...

    Silverlight: RadChart for Export to Image

    Good news everyone! Exporting Silverlight charts to images has been a common request for our Silverlight chart. I’m glad to announce that the functionality is already done and checked in our development branch. This means that everything is on track for the Q3 2009 release (and maybe a beta release before that!).   But why not for Q2? Well, there are a couple of reasons. Q2 release was still Silverlight 2 based and there were technological difficulties that didn’t allow us to implement this feature. Firstly, Silverlight 2 didn’t have the writeable bitmap class which facilitates rasterizing the chart rendering and secondly...

    RadChart for WPF/SL Automatic Data Binding to Nested Collections

    Seamless operation with diverse data sources is paramount for any data visualization solution. RadChart already supports automatic data binding to IEnumerable sources as seen in this example: http://demos.telerik.com/silverlight/#Chart/DataBinding. With the growing of Silverlight data sources and support for various data services, however, a new scenario is becoming more common: data binding to a collection of collections or nested collections. I am glad to announce that a new feature is coming in the Q2 2009 release which will make this automatic. Consider the following code snippet: private void FillWithData() {     var list1 = new List<double>() { 1, 3, 5, 7, 9 }; //Odd Numbers     var list2 = new List<double>() { 2, 4, 6, 8, 10 }; //Even Numbers    ...

    Integrating RadChart for Silverlight in existing ASP.NET applications

    There’s an emerging trend to integrate cool new silverlight controls into existing production asp.net solutions. And why wouldn’t it be there? There are many  asp.net applications in production out there that have been working quite well and don’t need to be replaced by a completely new technology. Wouldn’t it be nice, however, to spice them up a little with some rich silverlight visualization tools? This is exactly what a lot of our customers have been asking for lately. Well, here you can see some resources we published that will help anyone who wants to plug in RadChart for Silverlight in...

    RadChart for Silverlight

    Mid March is coming and there are a lot of good news for our Silverlight controls to be shared with all of you – the 2009 Q1 release is near. Along with the official version of RadGridView, RadDocking, RadEditor CTP and a bunch of new features and improvements, RadChart for Silverlight is also coming into play. With the 2009 Q1 release we'll introduce 2D charts for Silverlight that share the same appearance and behavior as their counterparts in WPF. This is due to the fact that both of the suites share common codebase and API. I’m sure the next question will be...
