Using Print Preview
|
|
|
Microsoft Visual Studio .NET provides the ability to
preview a document before printing it. To use it, you can use the
appropriate control but you must "draw" what you are planning to
print.
To start, you can create a Windows Forms Application
with a form designed as you wish. Here is an example:
You can then add a PrintDocument and a PrintPreviewDialog
controls to your form. When the
user clicks the menu item or button you had provided for print preview,
you can implement its event by drawing what will be printing, retrieving
values from existing controls. Here is an example from the above form:
