'Declaration
 
Public Overloads Sub PrintPreview( _

   ByVal printDocument As PrintDocument _
) 
public void PrintPreview( 
   UltraGridLayout layout,
   PrintDocument printDocument

Parameters

layout

printDocument
Optional print document
Remarks

The PrintPreview method initiates a print preview. Invoking this method triggers the process of preparing a printed report based on the data in the grid and displaying the results in a print preview window. This process has several steps and involves interaction between print-preview-specific objects and events within the control.

When you invoke this method, you specify a Layout object that controls the formatting of how the grid data will look when printed, and also while being previewed. The Layout object gives you the opportunity to create a custom-formated report based on the data in teh grid, applying different attributes such as fonts, colors and arrangement of data specifically for the printed page.

When the print preview begins, the InitializePrintPreview event occurs. This event receives a PrintDocument object that contains information about the print job being previewed. You examine and change the properties of this object to provide feedback for the user and control the look of the printed output. Any settings you have applied to the PrintDocument object specified as a paramter of the PrintPreview method will be passed along to the PrintDocument that appears in the InitializePrintPreview method.

Example
Following code shows how to print the UltraGrid and makes use of BeforePrint event to show a confirmation dialog before proceeding with printing the UltraGrid.

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.
