XMLNS for XAML: http://schemas.microsoft.com/winfx/2006/xaml/presentation, http://schemas.microsoft.com/netfx/2007/xaml/presentation

Syntax

C++

[TypeConverterAttribute(typeof(LengthConverter))]
public double PageWidth { get; set; }

<object PageWidth="qualifiedDouble"/>
- or -
<object PageWidth="Auto"/>

XAML Values

double

Double

String representation of a Double value equal to or greater than 0.0 but smaller than Double.PositiveInfinity. An unqualified value is measured in device independent pixels. Strings need not explicitly include decimal points.

qualifiedDouble

A double value as described above, followed by one of the following unit specifiers: px, in, cm, pt.

px (default) is device-independent units (1/96th inch per unit)

in is inches; 1in==96px

cm is centimeters; 1cm==(96/2.54) px

pt is points; 1pt==(96/72) px

Auto

Causes the page width to be determined automatically. Equivalent to a property value of Double.NaN.

Property Value

Type: System.Double
The preferred width, in device independent pixels, for pages in the FlowDocument. A value of Double.NaN (equivalent to an attribute value of "Auto") causes the page width to be determined automatically. The default is Double.NaN.

Dependency Property Information

Identifier field	PageWidthProperty
Metadata properties set to true	AffectsMeasure

Remarks

If viewed on a continuum, the MinPageWidth property takes precedence over the MaxPageWidth property, which in turn takes precedence over the PageWidth property. If all three properties are set on a given page, this is the order in which the properties are evaluated.

Examples

The following example shows how to set the PageWidth attribute of a FlowDocument element.

XAML

<FlowDocumentReader>
  <FlowDocument
    PageHeight="Auto"
    PageWidth="Auto"
    MinPageHeight="3in"
    MinPageWidth="5in"
    MaxPageHeight="6in"
    MaxPageWidth="10in"
  >
    <Paragraph Background="BlanchedAlmond">
      This uses automatic page sizing with minimum page size of 3 by 5 inches,
      and a maximum page size of 6 by 10 inches.
    </Paragraph>
  </FlowDocument>
</FlowDocumentReader>

The following example shows how to set the PageWidth property programmatically.

FlowDocument flowDoc = new FlowDocument(new Paragraph(new Run("A bit of text content...")));
// Set PageHeight and PageWidth to "Auto".
flowDoc.PageHeight = Double.NaN;
flowDoc.PageWidth = Double.NaN;
// Specify minimum page sizes.
flowDoc.MinPageWidth = 680.0;
flowDoc.MinPageHeight = 480.0;
//Specify maximum page sizes.
flowDoc.MaxPageWidth = 1024.0;
flowDoc.MaxPageHeight = 768.0;
