    RadChart for Silverlight in ASP.NET MVC Application

    The purpose of this blog post is to show how to incorporate RadChart for Silverlight in an ASP.NET MVC application. Manol has already shown how to do this for ASP.NET and things are not much different for ASP.NET MVC. Let’s start with a simple Silverlight application with a single RadChart. For simplicity, I will populate it with a list of numbers, you can also use any of the techniques, supported by RadChart. The code is as simple as this XAML: <telerik:RadChart x:Name="RadChart1" /> And C#: RadChart1.ItemsSource = new double[] { 3d, 4d, 6d };   I will create two write-only properties of the Silverlight user control -- ShowItemLabels and SeriesType. They are marked with  ScriptableMemberAttribute so...

    Some tricks with MEF up the sleeve of RadRichTextBox for Silverlight

    In Q2 we introduced the first official version of RadRichTextBox for Silverlight. In this blog post we want to share with you one of the main principles which we have followed while developing our brand new rich text editor for Silverlight - total extensibility. One of the key features which we have included is the ability to import/export from/to various document formats. For the first release we have already included some of the most widely used formats, such as .html/.docx/.xaml/.txt and in the next releases there are still more to come. As MEF is a wonderful technology, we have built...
