Public Property TextEffects As TextEffectCollection

Property Value

A TextEffectCollection containing one or more TextEffect objects that define effects to apply to the text of the TextBlock. The default is null (no effects applied).

Examples

The following example shows how to create a simple text effect and apply it to a text of a TextBlock.

// Create and configure a simple color animation sequence.  Timespan is in 100ns ticks.
ColorAnimation blackToWhite = new ColorAnimation(Colors.White, Colors.Black, new Duration(new TimeSpan(100000)));
blackToWhite.AutoReverse = true;
blackToWhite.RepeatBehavior = RepeatBehavior.Forever;

// Create a new brush and apply the color animation.
SolidColorBrush scb = new SolidColorBrush(Colors.Black);
scb.BeginAnimation(SolidColorBrush.ColorProperty, blackToWhite);

// Create a new TextEffect object; set foreground brush to the previously created brush.
TextEffect tfe = new TextEffect();
tfe.Foreground = scb;
// Range of text to apply effect to (all).
tfe.PositionStart = 0;
tfe.PositionCount = int.MaxValue;

// Create a new TextBlock with some text.
TextBlock textBlock = new TextBlock();
textBlock.Text = "Text that flickers...";

// The TextEffects property is null (no collection) by default.  Create a new one.
textBlock.TextEffects = new TextEffectCollection();

// Add the previously created effect to the TextEffects collection.
textBlock.TextEffects.Add(tfe);
' Create and configure a simple color animation sequence.  Timespan is in 100ns ticks.
Dim blackToWhite As New ColorAnimation(Colors.White, Colors.Black, New Duration(New TimeSpan(100000)))
blackToWhite.AutoReverse = True
blackToWhite.RepeatBehavior = RepeatBehavior.Forever

' Create a new brush and apply the color animation.
Dim scb As New SolidColorBrush(Colors.Black)
scb.BeginAnimation(SolidColorBrush.ColorProperty, blackToWhite)

' Create a new TextEffect object; set foreground brush to the previously created brush.
Dim tfe As New TextEffect()
tfe.Foreground = scb
' Range of text to apply effect to (all).
tfe.PositionStart = 0
tfe.PositionCount = Integer.MaxValue

' Create a new TextBlock with some text.
Dim textBlock As New TextBlock()
textBlock.Text = "Text that flickers..."

' The TextEffects property is null (no collection) by default.  Create a new one.
textBlock.TextEffects = New TextEffectCollection()

' Add the previously created effect to the TextEffects collection.
textBlock.TextEffects.Add(tfe)

Remarks

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