BulletCharacter Property

Description

Gets or sets the bullet character at the current input position. If text is selected, the property specifies the bullet character of the whole selected text.

Syntax

public char? BulletCharacter { get; set; }

Public Property BulletCharacter As Char?

Examples

The following XAML example shows how to bind the BulletCharacter property to a checkable menu item showing a diamond shaped bullet using the WPF.BooleanConverter class. (For other possible bullet characters see character codes of the "Symbol" font)

…
xmlns:tx="clr-namespace:TXTextControl.WPF;assembly=TXTextControl.WPF"
…
<Window.Resources>
    <tx:BooleanConverter x:Key="boolConv" />
</Window.Resources>
…
<MenuItem
    Header="&#x00A8;"
    FontFamily="Symbol"
    IsCheckable="True"
    IsChecked="{Binding
        ElementName=textControl1,
        Path=InputFormat.BulletCharacter,
        Converter={StaticResource boolConv},
        ConverterParameter=&#x00A8;}" />

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

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

inputFormat.BulletCharacter = 'A';
if (inputFormat.BulletCharacter != null)
{
    Console.WriteLine("Input Format: Bullet Character is available.");
}

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

inputFormat.BulletCharacter = "A"c
If inputFormat.BulletCharacter IsNot Nothing Then
    Console.WriteLine("Input Format: Bullet Character is available.")
End If

Remarks

The property returns null when the text selection contains several lists with different bullet characters.
