.NET Framework Class Library

TextBlock..::.LineStackingStrategy Property

Gets or sets the mechanism by which a line box is determined for each line of text within the TextBlock. This is a dependency property.

Namespace: System.Windows.Controls
Assembly: PresentationFramework (in PresentationFramework.dll)
XMLNS for XAML: http://schemas.microsoft.com/winfx/xaml/presentation

Syntax

Visual Basic (Declaration)

Public Property LineStackingStrategy As LineStackingStrategy

Visual Basic (Usage)

Dim instance As TextBlock
Dim value As LineStackingStrategy

value = instance.LineStackingStrategy

instance.LineStackingStrategy = value

public LineStackingStrategy LineStackingStrategy { get; set; }

Visual C++

public:
property LineStackingStrategy LineStackingStrategy {
    LineStackingStrategy get ();
    void set (LineStackingStrategy value);
}

JScript

public function get LineStackingStrategy () : LineStackingStrategy
public function set LineStackingStrategy (value : LineStackingStrategy)

XAML Attribute Usage

<object LineStackingStrategy="LineStackingStrategy" .../>

Property Value

Type: System.Windows..::.LineStackingStrategy
The mechanism by which a line box is determined for each line of text within the TextBlock. The default is LineStackingStrategy..::.MaxHeight.

Dependency Property Information

Identifier field	LineStackingStrategyProperty
Metadata properties set to true	AffectsMeasure, AffectsRender

Remarks

This dependency property also has an attached property usage. In XAML, the usage is <object TextBlock..::.LineStackingStrategy="value".../>, where object is an object element (typically a flow element) contained within a TextBlock, and value is a string value of the LineStackingStrategy enumeration. In code, the attached property usage is supported by GetLineStackingStrategy and SetLineStackingStrategy. The attached property usage is not common.

Examples

The following example shows how to use the LineStackingStrategy property to determine how the line boxes are created for text lines of a TextBlock. The first TextBlock has a LineStackingStrategy value of MaxHeight and the second TextBlock has a value of BlockLineHeight.

<Page xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
  xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
  <StackPanel>

    <!-- This TextBlock has a LineStackingStrategy set to "MaxHeight". -->
    <TextBlock LineStackingStrategy="MaxHeight" LineHeight="10" Width="500" TextWrapping="Wrap" 
     Background="Yellow">
      Use the <Span FontSize="30">LineStackingStrategy</Span> property to determine how a line box is
      created for each line. A value of <Span FontSize="20">MaxHeight</Span> specifies that the stack
      height is the smallest value that contains all the inline elements on that line when those
      elements are properly aligned. A value of <Span FontSize="20">BlockLineHeight</Span> specifies
      that the stack height is determined by the block element LineHeight property value.
    </TextBlock>

    <!-- Here is the same TextBlock but the LineStackingStrategy is set to "BlockLineHeight". -->
    <TextBlock LineStackingStrategy="BlockLineHeight" LineHeight="10" Width="500" TextWrapping="Wrap" 
     Background="Blue" Margin="0,40,0,0">
      Use the <Span FontSize="30">LineStackingStrategy</Span> property to determine how a line box is
      created for each line. A value of <Span FontSize="20">MaxHeight</Span> specifies that the stack
      height is the smallest value that contains all the inline elements on that line when those
      elements are properly aligned. A value of <Span FontSize="20">BlockLineHeight</Span> specifies
      that the stack height is determined by the block element LineHeight property value.
    </TextBlock>

  </StackPanel>
