Syntax
'Declaration
Public Property FontSize As Double
public double FontSize { get; set; }
<textElement FontSize="double" ... />
Property Value
Type: System.Double
The desired font size in pixels. The default is 11 pixels.
Remarks
Dependency property identifier field: FontSizeProperty
In Windows Presentation Foundation (WPF), the XAML values for FontSize can include a unit qualifier such as "pt" or "px". However, these unit qualifiers are not supported in Silverlight. You must specify a numeric value only, which is always interpreted as pixels. If you are importing XAML UI definitions from WPF, you must adjust the FontSize attribute values to strip the unit qualifiers, including "px" (this might also involve converting the previous units to pixel values). Otherwise, parsing the XAML will fail.
FontSize does not affect the height of the line break. Only the FontSize set on the text runs themselves has any effect. The line height for a LineBreak is influenced by the surrounding runs, but multiple line breaks in succession use the default 11 pixel height. (LineStackingStrategy can also influence this spacing.)
