XAML Values

double

Double

A string representation of a Double value. This is interpreted as a device-independent unit (1/96th inch) measurement. Strings need not explicitly include decimal points. For example, a value of 1 is acceptable.

The same Double range restrictions that are mentioned in the Property Value section apply here.

qualifiedDouble

A double value as previously described that is followed by one of these unit declaration strings: 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

Note   In many cases a double may be set to "Auto," but a Control::FontSize does not render if set to "Auto".

Property Value

Type: System::Double
The size of the text in the Control. The default is SystemFonts::MessageFontSize. The font size must be a positive number.

This property only affects a control whose template uses the FontSize property as a parameter. On other controls, this property has no impact.

The following example shows how to set the font size property of a control.

<Button Name="btn3" FontSize="10.0" 
        Click="ChangeFontSize">
  FontSize
</Button>
