Introduction In one of the previous blog posts, we gave you a quick overview of how to use RadImageEditorUI to add a basic image editor to your application in a few simple steps. However, there is often a need for more customized image editing capabilities, in which case you can use the bare-bone RadImageEditor control. It doesn’t force a specific UI, so you can choose one that will best integrate in your application. Whereas RadImageEditorUI contains all the UI you need from a basic image editor, RadImageEditor consists only of the image that is being edited. It has an API that...

We hope you will share our excitement of announcing the brand new member of Telerik’s XAML suite – the RadPropertyGrid. This control will be officially available with the Q2 2011 release that is coming in the midst of July, but now it is included in our recently released Beta for early preview and to satisfy your curiosity. RadPropertyGrid introduces an intuitive and versatile approach to data processing and visualization. Unlike the widely beloved RadDataForm, RadPropertyGrid sets the focus on a single item rather than on a collection of items, exposing many useful features as grouping and search as you type....

Windows 8 will bring exciting times to all application developers, especially those who will invest in creating the immersive applications we all saw in that video . We loved the tiles and the clean modern look and how they integrate perfectly within the UI. And I am guessing a lot of software will transition to new ways. As always Telerik will ease this process by providing its Silverlight and WPF offering with Metro UI Theme and kick start your Windows 8 development. The theme is built from the ground-up to accommodate all the best practices in Metro UI applications. Line of Business Ready

Developing and supporting MVVM applications is easy and effective. That's why we want to create MVVM applications that follow this pattern. Sometimes the controls we use have some limitations. For example, list properties, which are read-only and do not allow us to create an appropriate binding to our view-models. It is normal for properties of list type to be read-only, because this is considered a good practice, but it becomes a problem for the MVVM pattern. In the ItemsControl this problem is solved with two properties - Items and ItemsSource. This blog post is about an example that demonstrates how to create...

RadChart allows you to programmatically filter its data using FilterDescriptors as demonstrated in our help topic. However there are scenarios where you would like to have more complex filtering. For a sample scenario where a Chart is drawn according to the filtered RadGridView’s data - read further. The Chart and the GridView will be populated with the same data source – List of Business Objects: public class MyDateObject   {       public double SampleValue { get; set; }       public DateTime Date { get; set; }   }     public class MyDataContext   {       public const int min = 20;       public const int max = 80;       public ObservableCollection<MyDateObject> List { get; set; }       Random r = new Random();       DateTime baseDate = DateTime.Today;         public MyDataContext()       {           this.CreateChartData();       }         private void CreateChartData()       {           List = new ObservableCollection<MyDateObject>();           for (int i = 0; i < 15; i++)           {               List.Add(new MyDateObject() { SampleValue = r.Next(min,...
