Public Property MaxTextHeight As Double

Property Value

Type: System.Double

The maximum height of a text column, provided in device-independent units (1/96th inch per unit).

The last line of text displayed is the last whole line that will fit within the MaxTextHeight limit or the line number that does not exceed the MaxLineCount property, whichever occurs first.

The following example creates a FormattedText object and then applies several formatting styles to the text, including MaxTextHeight.

Protected Overrides Sub OnRender(ByVal drawingContext As DrawingContext)
	Dim testString As String = "Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor"

	' Create the initial formatted text string.
	Dim formattedText As New FormattedText(testString, CultureInfo.GetCultureInfo("en-us"), FlowDirection.LeftToRight, New Typeface("Verdana"), 32, Brushes.Black)

	' Set a maximum width and height. If the text overflows these values, an ellipsis "..." appears.
	formattedText.MaxTextWidth = 300
	formattedText.MaxTextHeight = 240

	' Use a larger font size beginning at the first (zero-based) character and continuing for 5 characters.
	' The font size is calculated in terms of points -- not as device-independent pixels.
	formattedText.SetFontSize(36 * (96.0 / 72.0), 0, 5)

	' Use a Bold font weight beginning at the 6th character and continuing for 11 characters.
	formattedText.SetFontWeight(FontWeights.Bold, 6, 11)

	' Use a linear gradient brush beginning at the 6th character and continuing for 11 characters.
	formattedText.SetForegroundBrush(New LinearGradientBrush(Colors.Orange, Colors.Teal, 90.0), 6, 11)

	' Use an Italic font style beginning at the 28th character and continuing for 28 characters.
	formattedText.SetFontStyle(FontStyles.Italic, 28, 28)

	' Draw the formatted text string to the DrawingContext of the control.
	drawingContext.DrawText(formattedText, New Point(10, 0))
End Sub
