Gets or sets a value that specifies the text decorations that are applied to the content in a TextBlock element.
Assembly: System.Windows (in System.Windows.dll)
Dependency property identifier field: TextDecorationsProperty
A text decoration is a visual ornament that you can add to text. WPF supports APIs that let you define a custom text decoration. Silverlight 5 supports only one type of text decoration: Underline. The type name of type used to set this property (TextDecorationCollection) suggests multiple possible values, but only one value is supported. The name provides compatibility between Silverlight and WPF. The TextDecorationCollection object in Silverlight supports only object. It does support Collection interface APIs or a public constructor..
In XAML, you can set to the value Underline or to an empty string (equivalent to no underline).
In code, you can set the value of to Underline or to null. Setting the value to null effectively restores the default value if it has been set to Underline in XAML or code previously .
settings for Run child elements override this top-level setting.
The following code example shows how you can use the TextDecorations property to underline the text in a TextBlock.
