Gets or sets the font size.
(in PresentationFramework.dll)XMLNS for XAML:
Public Property FontSize As Double
- or –
<object FontSize ="qualifiedDouble"/>
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.
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".
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"
Private Sub ChangeFontSize(ByVal Sender As Object, ByVal e As RoutedEventArgs)
fsize = btn3.FontSize
If (fsize = 16.0) Then
btn3.FontSize = 10.0
btn3.Content = "FontSize"
btn3.FontSize = 16.0
btn3.Content = "Control font size changes from 10 to 16."
