A TextDecoration object is a visual ornamentation you can add to text. There are four types of text decorations: underline, baseline, strikethrough, and overline. For more information about text decorations, see How to: Create a Text Decoration.

By default, this property is set to null and has no TextDecorationCollection associated with it. Before adding any text effects, create a new TextDecorationCollection and assign it to this property.

The following example shows how to set the TextDecorations attribute.

<TextBlock TextDecorations="Strikethrough">
  This text will render with the strikethrough effect.
</TextBlock>

The following figure shows how this example renders.

Screenshot: Text with default strikethrough effect

The following figures show how the OverLine, Baseline, and Underline decorations render, respectively.

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

TextBlock textBlock = new TextBlock(new Run("This text will render with the strikethrough effect."));
textBlock.TextDecorations = TextDecorations.Strikethrough;
