Watermark.PageRange Property

Gets or sets the range of pages which contain a watermark.

Namespace: DevExpress.XtraPrinting.Drawing

Assembly: DevExpress.Printing.v24.1.Core.dll

NuGet Package: DevExpress.Printing.Core

Declaration

C#

[XtraSerializableProperty]
public string PageRange { get; set; }

VB.NET

<XtraSerializableProperty>
Public Property PageRange As String

Property Value

Type	Description
String	A String specifying the range of pages which contain a watermark.

Remarks

The PageRange property’s value contains the range of pages on which a watermark is displayed. The ranges are separated by commas. For example: “1,3,5-12”.

Note

If not all pages from the specified page range exist in the current document, invalid page numbers are ignored. So, only valid page numbers are taken into account.

If there are no valid page numbers in the page range string, the watermark is added to all pages of the document.

Example

This example demonstrates how to add a watermark to a printing system document. The SetTextWatermark method demonstrates the properties that are used to specify settings when a text watermark is added to a document, while the SetPictureWatermark method demonstrates the properties required to set a picture as a document’s watermark.

C#

using System.Drawing;
using DevExpress.XtraPrinting;
using DevExpress.XtraPrinting.Drawing;
using DevExpress.Drawing;
// ...

public void SetTextWatermark(PrintingSystem ps){
   // Create the text watermark.
   Watermark textWatermark = new Watermark();

   // Set watermark options.
   textWatermark.Text = "CUSTOM WATERMARK TEXT";
   textWatermark.TextDirection = DirectionMode.ForwardDiagonal;
   textWatermark.Font = new DXFont(textWatermark.Font.FontFamily, 40);
   textWatermark.ForeColor = Color.DodgerBlue;
   textWatermark.TextTransparency = 150;
   textWatermark.TextPosition = WatermarkPosition.InFront;
   textWatermark.PageRange = "1,3-5";

   // Add the watermark to the collection.
   ps.Watermarks.Add(textWatermark);
}

public void SetPictureWatermark(PrintingSystem ps){
   // Create the picture watermark.
   Watermark pictureWatermark = new Watermark();

   // Set watermark options.
   pictureWatermark.Image = Bitmap.FromFile("watermark.gif");
   pictureWatermark.ImageAlign = ContentAlignment.TopCenter;
   pictureWatermark.ImageTiling = false;
   pictureWatermark.ImageViewMode = ImageViewMode.Stretch;
   pictureWatermark.ImageTransparency = 150;
   pictureWatermark.ImagePosition = WatermarkPosition.Behind;
   pictureWatermark.PageRange = "2,4";

   // Add the watermark to the collection.
   ps.Watermarks.Add(pictureWatermark);
}
