PrintPreviewControl (Clase)
Actualización: noviembre 2007
Representa la parte de vista previa original de una vista previa de impresión de una aplicación de formularios Windows Forms, sin botones ni cuadros de diálogo. La mayoría de los objetos PrintPreviewControl se encuentran en los objetos PrintPreviewDialog, pero no necesariamente tiene que ser así.
Ensamblado: System.Windows.Forms (en System.Windows.Forms.dll)
Cuando se crea una instancia de la clase PrintPreviewControl, se establecen algunas propiedades de lectura y escritura en sus valores iniciales. Para obtener una lista de esos valores, vea el constructor PrintPreviewControl.
Para obtener más información acerca de cómo imprimir con formularios Windows Forms, vea la información general relacionada con el espacio de nombres System.Drawing.Printing. Si desea imprimir desde una aplicación de Windows Presentation Foundation, vea el espacio de nombres System.Printing.
En el ejemplo de código siguiente se muestran las propiedades Document, UseAntiAlias y Zoom del control PrintPreviewControl. Para ejecutar este ejemplo, coloque el código siguiente en un formulario y llame al método InitializePrintPreviewControl desde el constructor del formulario o desde el método de control de eventos de Load.
// Declare the PrintPreviewControl object and the // PrintDocument object. internal PrintPreviewControl PrintPreviewControl1; private System.Drawing.Printing.PrintDocument docToPrint = new System.Drawing.Printing.PrintDocument(); private void InitializePrintPreviewControl() { // Construct the PrintPreviewControl. this.PrintPreviewControl1 = new PrintPreviewControl(); // Set location, name, and dock style for PrintPreviewControl1. this.PrintPreviewControl1.Location = new Point(88, 80); this.PrintPreviewControl1.Name = "PrintPreviewControl1"; this.PrintPreviewControl1.Dock = DockStyle.Fill; // Set the Document property to the PrintDocument // for which the PrintPage event has been handled. this.PrintPreviewControl1.Document = docToPrint; // Set the zoom to 25 percent. this.PrintPreviewControl1.Zoom = 0.25; // Set the document name.
