Syntax
'Declaration
 
Public Function PerformAction( _
   ByVal actionCode As UltraPrintPreviewControlAction _
) As Boolean
public bool PerformAction( 
   UltraPrintPreviewControlAction actionCode
)

Parameters

actionCode
The action to perform.

Return Value

True if action was performed.
Remarks

PerformAction simulates user interaction with the control. Calling Peformaction will cause the control to behave as through the user performed the specified action. Any appropriate events will be called as if the user performed the action.

Example
This snippet demonstrates how to create a user interface which allows the user to navigate the view history of a print preview. Every time the user moves to a different part of the print preview the new view is saved by the UltraPrintPreviewControl. The location in the preview, zoom factor, etc. are all saved in this history list. This is analogous to the Back and Forward history buttons in an internet browser.
