AutoGeneratePreview Property

Returns or sets whether the preview is automatically created when the document is changed and when the control is first displayed.
Syntax
public bool AutoGeneratePreview {get; set;}
Remarks

The AutoGeneratePreview property is used to determine whether the control should automatically create the print preview pages when they are needed. Normally, the preview pages are automatically generated when the control is rendered. You can set this property to false to prevent that behavior. You would then need to explicitly call the GeneratePreview when you want the preview pages to be synchronously generated.

Example
This sample demonstrates how to configure several properties of the UltraPrintPreviewControl.

Public Sub New()

   InitializeComponent()
   
   ' Give the control a reference to a PrintDocument-derived object.
   Me.ultraPrintPreviewControl1.Document = Me.ultraSchedulePrintDocument1
   
   ' Turn off the AutoGeneratePreview feature.
   ' If you do this you will be responsible for telling the control 
   ' when to start the preview operation using the GeneratePreview method.
   ' Alternatively you can set the DisplayPreviewStatus to false and it will 
   ' run the print operation but not show a status dialog.
   Me.ultraPrintPreviewControl1.AutoGeneratePreview = False
   Me.ultraPrintPreviewControl1.DisplayPreviewStatus = False
   
   ' Only allow for up to three preview pages to be generated.
   Me.ultraPrintPreviewControl1.MaximumPreviewPages = 3
   
   ' If the resolved mouse action is not already DynamicZoom, make it so.
   If Me.ultraPrintPreviewControl1.MouseActionResolved <> Infragistics.Win.Printing.PreviewMouseAction.DynamicZoom Then
      Me.ultraPrintPreviewControl1.MouseAction = Infragistics.Win.Printing.PreviewMouseAction.DynamicZoom
   End If 

   ' Use anti-aliasing to ensure that the image is smooth and clear.
   Me.ultraPrintPreviewControl1.UseAntiAlias = True

End Sub
