From protecting against unauthorized use to establishing ownership and authenticity, text and picture watermarks can serve as digital fingerprints. With our most recent update (v23.2), DevExpress Reports ships with enhanced watermark capabilities – designed to display different watermarks within report documents based on page index.
Display Different Watermarks
With v23.2, the XtraReport class now features the WatermarkСollection class that stores the Watermark objects.
To manage the watermarks collection, invoke the Watermarkscollection editor:
Watermark.PageRange property:

Locate Watermark Elements on the Same Page
We split watermark position for text and image within one watermark. You can now manage PageWatermark.TextPosition and PageWatermark.ImagePosition properties of the watermark to specify whether text and picture should be displayed behind or in front of page content.

Display Watermarks by a Condition
You can add watermarks to a document based on a condition using the XtraReport.WatermarkId property. This property allows you to apply a specific watermark to a page based on the watermark Id or expression binding. Note: Page.AssignWatermark takes priority over the specified WatermarkId property.
For example, the following expression adds different watermarks to the first, odd, and even pages of a report:
Iif([Arguments.PageIndex]=0,'watermark1',Iif([Arguments.PageIndex]%2=0,'watermark2','watermark3'))
