SizeModeChanged Event
See Also  Example
Leadtools.WinForms Namespace > RasterImagePrinter Class : SizeModeChanged Event




Occurs when the value of the SizeMode property changes.

Syntax

Visual Basic (Declaration) 
Public Event SizeModeChanged() As EventHandler
Visual Basic (Usage)Copy Code
Dim instance As RasterImagePrinter
Dim handler As EventHandler
 
AddHandler instance.SizeModeChanged, handler
C# 
public event EventHandler SizeModeChanged()
Managed Extensions for C++ 
public: __event EventHandler* SizeModeChanged();
C++/CLI 
public:
event EventHandler^ SizeModeChanged();

Example

This example uses events to detect changes to a RasterImagePrinter object.
