Gets or sets the preferred height for pages in a FlowDocument.

public:
 property double PageHeight { double get(); void set(double value); };

[System.ComponentModel.TypeConverter(typeof(System.Windows.LengthConverter))]
public double PageHeight { get; set; }

[<System.ComponentModel.TypeConverter(typeof(System.Windows.LengthConverter))>]
member this.PageHeight : double with get, set

Public Property PageHeight As Double

Property Value

Double

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

Attributes: TypeConverterAttribute

Examples

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

<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 PageHeight 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;

Dim flowDoc As 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

Remarks

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

XAML Attribute Usage

<object PageHeight="double"/>
- or -
<object PageHeight="qualifiedDouble"/>
- or -
<object PageHeight="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 height to be determined automatically. Equivalent to a property value of Double.NaN.
