XAML Values

double

Double

String representation of a Double value equal to or greater than 0.0034 and equal to or less then 160000. An unqualified value is measured in device independent pixels. Strings need not explicitly include decimal points.

qualifiedDouble

A double value as described above, (excepting Auto) 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 line height to be determined automatically from the current font characteristics. Equivalent to a property value of NaN.

Property Value

Type: System.Double
A double value specifying the height of line in device independent pixels. LineHeight must be equal to or greater than 0.0034 and equal to or less then 160000.
A value of NaN (equivalent to an attribute value of "Auto") causes the line height to be determined automatically from the current font characteristics.
The default value is NaN.

ExceptionCondition
ArgumentException

Raised if an attempt is made to set LineHeight to a non-positive value.

Changing this value does not change the height of the associated text; rather, it changes the height of the line that contains the text.

In addition to this property, the layout of lines in a TableCell is affected by its LineStackingStrategy property.

The following example shows how to set the LineHeight attribute of a Block element.

<FlowDocument>
  <Paragraph 
    TextAlignment="Left" 
    Background="AliceBlue"
    FontSize="24"
    LineHeight="48"
  >
    One<LineBreak/>
    two two<LineBreak/>
    Three Three Three<LineBreak/>
    four four four four<LineBreak/>
    Five Five Five Five Five
  </Paragraph>
</FlowDocument>

The following figure shows how the previous example renders.

The following figure shows how the same example renders with the default setting of LineHeight=NaN.

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

Paragraph par = new Paragraph();
par.LineHeight = 48;
