Syntax
'Declaration
 
Public Property NewSize As Size
public Size NewSize {get; set;}

Example
The following code sample demonstrates how to use the BeforeNodeLayoutItemResize and AfterNodeLayoutItemResize events.

For an overview of how to handle events in Visual Basic or Visual C#, see Event Handlers in Visual Basic and Visual C#. For specific information and code examples illustrating how to consume events in your application, see Consuming Events in the .NET Framework Developer's Guide.
