Namespace:  System.Windows.Controls

Public Property FontSource As FontSource
public FontSource FontSource { get; set; }

Property Value

Type: System.Windows.Documents.FontSource
The font source used to render content in the text box. The default is nulla null reference (Nothing in Visual Basic).


Exception Condition

The value set is not a valid source.


If the FontSource property is set to nulla null reference (Nothing in Visual Basic), any assigned custom font is cleared and the TextBox renders with the default font.


The following code example shows how you can set the FontSource property.

Private Sub AddFont()

    'Set the font to Times New Roman using FontSource property.
    Dim MyTextBox As TextBox = New TextBox
    MyTextBox.Text = "hello world"
    Dim MyUri As Uri = New Uri("times.ttf", UriKind.Relative)
    Dim MySRI As StreamResourceInfo = Application.GetResourceStream(MyUri)
    MyTextBox.FontSource = New FontSource(MySRI.Stream)
    MyTextBox.FontFamily = New FontFamily("Times New Roman")

    'Add the textbox to the stackpanel
End Sub
private void AddFont()
    //Set the font to Times New Roman using FontSource property.
    TextBox MyTextBox = new TextBox();
    MyTextBox.Text = "hello world";
    Uri MyUri = new Uri("times.ttf", UriKind.Relative);
    StreamResourceInfo MySRI = Application.GetResourceStream(MyUri);
    MyTextBox.FontSource = new FontSource(MySRI.Stream);
    MyTextBox.FontFamily = new FontFamily("Times New Roman");

    //Add the textbox to the stackpanel
