### Description

Gets or sets a value specifying whether the text is strikeout at the current input position. If text is selected, the property specifies this attribute for the whole selected text.

### Syntax

```csharp
public bool? Strikeout { get; set; }
```

```vbnet
Public Property Strikeout As Boolean?
```

### Examples

The following XAML example binds the Strikeout property to a check box:

```plaintext
<CheckBox
    Height="20"
    Name="checkBoxStrikeout"
    IsChecked="{Binding ElementName=textControl1, Path=InputFormat.Strikeout, Mode=TwoWay}">
    Strikeout</CheckBox>
```

The following example changes the formatting applied to text entered at the end of a document by using `InputFormat.Strikeout`.

```csharp
textControl.Text = "Project summary";
textControl.InputPosition = new InputPosition(textControl.Text.Length);
InputFormat inputFormat = textControl.InputFormat;

inputFormat.Strikeout = true;
if (inputFormat.Strikeout != null)
{
    Console.WriteLine("Input Format: Strikeout is available.");
}
```

```vbnet
textControl.Text = "Project summary"
textControl.InputPosition = New InputPosition(textControl.Text.Length)
Dim inputFormat As InputFormat = textControl.InputFormat

inputFormat.Strikeout = True
If inputFormat.Strikeout IsNot Nothing Then
    Console.WriteLine("Input Format: Strikeout is available.")
End If
```

### Remarks

The property returns null when the text selection contains multiple characters with mixed setting.
