#289 – Editing WPF Code-Behind in Blend

WPF applications are made up of markup (XAML) and code-behind (managed code).  The markup defines the layout and appearance of the application, whereas the code-behind defines the behavior.

You can use the code editor in either Visual Studio or Blend to edit code-behind.

The code editor in Blend is similar to the editor in Visual Studio, providing color coding and Intellisense.

You can open the code editor in several different ways.

Double-click the code file from the Project window.  For C#, this is a .cs file.

Right-click the code file in the Project window and select Open.

Note that in both cases, you need to first expand the parent .xaml file in the project hierarchy.  The code-behind is listed under its associated .xaml file.
