RadioButton and CheckBox Menu Items with RadMenu for Silverlight
RadMenu for Silverlight supports simple checkable items, but still does not support radio button items. This feature is scheduled for development and most probably will come with Q3 2009, but until then you have to code it by yourself. Fortunately, this is relatively easy with a proper ViewModel, that contains the radio-button logic: The CommandItem class contains the properties and the logic for a RadMenuItem. It implements INotifyPropertyChanged and its most important property is IsChecked: public bool IsChecked { get { return this.isChecked; } set ...June 19, 2009 -

Scrollable Menu – Workaround with a Multi-Column Menu and RadControls for Silverlight
RadMenu and RadContextMenu for Silverlight cannot automatically scroll their items if their height exceeds a certain height. We are planning to implement this feature in the near future, but at the moment there are two workarounds for the developers: override the RadMenu control template and add ScrollViewer controls around the ItemsPresenters, or customize the ItemsPanel of the RadMenuItem controls, so the sub-items are displayed in columns. The second option is much easier and looks good enough: The main idea is to replace the RadMenuItem ItemsPanel, that is a StackPanel by default, with a WrapPanel. To set the ItemsPanel property of all...June 19, 2009 -
Web ASP.NET AJAX
Using the RadFileExplorer for ASP.NET AJAX in a MOSS web application
The RadFileExplorer is a fairly new control in our ASP.NET AJAX suite and we are happy to see that a lot of people are already adopting it into their solutions. In this post I will show how to make the file explorer work with SharePoint libraries. By default, the control interfaces with a virtual folder in your web application and allows you to do all kinds of file/folder operations (create new folders, upload/move/delete items, preview, etc.). Unfortunately, the default behavior of the control is limited to virtual folders that can be mapped to physical locations on the server's drives. MOSS web...June 17, 2009

Binding a ComboBox to Enum Values with RadControls for Silverlight
A common request in our support is to display a combo box, containing all values of a specific Enum. This is fairly easy with RadComboBox for Silverlight - all you need to do is to fill its ItemsSource collection with the Enum values. The best way to do this is to create a view model for the Enum: using System; using System.Collections; using System.Linq; using System.Reflection; namespace SilverlightApplication1 { public class EnumModel { private Type enumType; public IEnumerable Values { get; private set; } [TypeConverter(typeof(TypeTypeConverter))] ...June 12, 2009 -

Silverlight/WPF RadChart axis improvements.
Along with the numerous updates that are coming up with the Q2.2009 version of RadChart for WPF/SL, we are going to introduce significant improvements of the way our horizontal axis handles user data. Actually, a bunch of new features will make the horizontal axis much more intelligent and easy to use. First of all, the horizontal axis will be able to properly handle "X" value data! As soon as a DataPoint with meaningful "X" value is received, the horizontal axis will enter "strict" mode and will place it appropriately. To make this possible we also implemented the following supporting features: Automatic range calculation...June 04, 2009
