Implemented functionality that detects a connection creation being cancelled through the Esc key and notifies the user

In order to take advantage of this functionality you should inherit the ConnectionTool of RadDiagram and override the KeyDown method - if it returns true the tool action has been canceled.
More about how to customize RadDiagram tools you can find in our help topic " Tools Customization": http://www.telerik.com/help/wpf/raddiagram-tools-customization.html
