Identifier field


Metadata properties set to true


By default, this property is set to Nothing and has no TextEffectCollection associated with it. Before adding any text effects, create a new TextEffectCollection and assign it to this property.

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.
			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.
