'Declaration Public Event BeforePrint As BeforePrintEventHandler
public event BeforePrintEventHandler BeforePrint
The event handler receives an argument of type CancelablePrintEventArgs containing data related to this event. The following CancelablePrintEventArgs properties provide information specific to this event.
Property | Description |
---|---|
Cancel (Inherited from System.ComponentModel.CancelEventArgs) | |
DefaultLogicalPageLayoutInfo | The default layout info, for all logical pages |
PrintDocument | The print document (read-only) |
PrintLayout | Returns the print layout. |
The BeforePrint event occurs before the report is sent to the printer, but after the user has had the opportunity to configure the print job using the Print and Page Setup dialogs. The Print and Page Setup dialogs can be made available to the user when invoking the Print method, and will contain any default settings you have specified for the print job in the InitializePrint event. The BeforePrint event is the last opportunity you have to change the parameters of a print job before it is committed to the print queue.
You can use the BeforePrint event to programmatically examine any changes to the PrintInfo object resulting from the user's actions. You can then choose to modify the user's settings where appropriate, or store them for later use.
The PrintInfo object is only accessible during this event, the InitializeLogicalPrintPage event, the InitializePrint event and the InitializePrintPreview event.
