Description

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

Syntax

public string FontFamily { get; set; }

Public Property FontFamily As String

Examples

The following XAML example shows how to bind a combo box to the FontFamily property using GetFontFamilies to fill the combo box with available font names.

<ComboBox
    Name="cbFontFamily"
    IsEditable="True"
    IsReadOnly="True"
    Width="150"
    DropDownOpened="cbFontFamily_DropDownOpened"
    Text="{Binding ElementName=textControl1, Path=InputFormat.FontFamily}" />

private void cbFontFamily_DropDownOpened(object sender, EventArgs e) {
    cbFontFamily.ItemsSource = textControl1.InputFormat.GetFontFamilies();
}

Private Sub cbFontFamily_DropDownOpened(sender As Object, e As EventArgs)
    cbFontFamily.ItemsSource = textControl1.InputFormat.GetFontFamilies()
End Sub

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

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

inputFormat.FontFamily = "Arial";
if (!string.IsNullOrWhiteSpace(inputFormat.FontFamily))
{
    Console.WriteLine($"Font Family: {inputFormat.FontFamily}");
}

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

inputFormat.FontFamily = "Arial"
If Not String.IsNullOrWhiteSpace(inputFormat.FontFamily) Then
    Console.WriteLine($"Font Family: {inputFormat.FontFamily}")
End If

Remarks

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