This week on XAMLflix we take a look at the RadExpressionEditor.

XAMLflix are our video tutorials designed to teach you everything you need to know to get started with and to learn about the features of Telerik’s RadControls for Silverlight and WPF.  We release a new XAMLflix video every Tuesday and Thursday and a XAMLflix written and searchable PDF tutorial every Wednesday.

Notice that you only have to learn how to use the RadExpressionEditor once because the Silverlight and WPF controls share a common code base and API.

RadExpressionEditor allows you to embed an expression editor into your program which in turn allows your users to build powerful LINQ expressions using a simple Domain-Specific language.  This is very similar to the way formulas are built in many popular spread-sheet applications.

The true power of RadExpressionEditor is seen when it is combined with he RadGridView. This allows your user to filter the results in the RadGridView using sophisticated LINQ expressions without having to know the LINQ syntax in advance.

This week we have two videos on RadExpressionEditor

  • Getting Started With RadExpressionEditor. This video introduces the RadExpressionEditor and shows how to add the editor to your application with a single line of code. The video briefly reviews the functionality of the editor in a running application. (Download the project)
  • RadExpressionEditor And RadGridView. This video demonstrates the power of combining the RadExpressionEditor with other Telerik controls.  In this video we combine the ExpressionEditor with the RadGridView, allowing the end user to filter the results displayed in the GridView using the generated LINQ statements and to see the results instantly.  (Download the project)


Telerik XAMLflix for WPF controls In these two videos you saw how incredibly easy it is to add a RadExpressionEditor to your project, and to bind it to other RadControls.

Remember that RadExpressionEditor is only one of the controls offered in the Silverlight/WPF suite. Download your own copy of the Silverlight and WPF control suite.

XAMLflix depends on your feedback. Please take a moment to leave a comment on what you’d like to see more (or less!) of in future XAMLflix videos.
