Examples

Each example shown here renders the same result. However, setting the Text property directly on the TextBlock has the best performance.

<!-- Set the TextBlock.Text property directy for best performance. -->
<TextBlock Text="This is some text."/>

<TextBlock><Run>This is some text.</Run></TextBlock>

<TextBlock><Run Text="This is some text."></Run></TextBlock>

// Set the TextBlock.Text property directy for best performance.
TextBlock textblock = new TextBlock();
textblock.Text = "This is some text.";

TextBlock textblock = new TextBlock();
Run run = new Run();
run.Text = "This is some text.";
textblock.Inlines.Add(run);

Remarks

A Run represents a discrete section of formatted or unformatted text and can be used in a TextBlock or RichTextBlock. You can place multiple Run elements inside of a Span.

When you use a TextBlock, set the TextBlock.Text property directly for best performance. You typically use the Run element only when you want to format a discrete section of text within the TextBlock.

Initializes a new instance of the Run class.

Properties

AccessKey	Gets or sets the access key for this element. (Inherited from TextElement)
AccessKeyScopeOwner	Gets or sets a source element that provides the access key scope for this element, even if it's not in the visual tree of the source element. (Inherited from TextElement)
AllowFocusOnInteraction	Gets or sets a value that indicates whether the element automatically gets focus when the user interacts with it. (Inherited from TextElement)
CharacterSpacing	Gets or sets the uniform spacing between characters, in units of 1/1000 of an em. (Inherited from TextElement)
ContentEnd	Gets a TextPointer that represents the end of the content in the element. (Inherited from TextElement)
ContentStart	Gets a TextPointer that represents the start of content in the element. (Inherited from TextElement)
Dispatcher	Gets the CoreDispatcher that this object is associated with. The CoreDispatcher represents a facility that can access the DependencyObject on the UI thread even if the code is initiated by a non-UI thread. (Inherited from DependencyObject)
ElementEnd	Gets a TextPointer that represents the position just after the end of the element. (Inherited from TextElement)
ElementStart	Gets a TextPointer that represents the position just before the start of the element. (Inherited from TextElement)
ExitDisplayModeOnAccessKeyInvoked	Gets or sets a value that specifies whether the access key display is dismissed when an access key is invoked. (Inherited from TextElement)
FlowDirection	Gets or sets the direction that text and other user interface elements flow within the Run element that controls their layout.
FlowDirectionProperty	Identifies the FlowDirection  dependency property.
FontFamily	Gets or sets the preferred top-level font family for the content of the element. (Inherited from TextElement)
FontSize	Gets or sets the font size for the content of the element. (Inherited from TextElement)
FontStretch	Gets or sets the glyph width of the font in a family to select. (Inherited from TextElement)
FontStyle	Gets or sets the font style for the content in this element. (Inherited from TextElement)
FontWeight	Gets or sets the top-level font weight to select from the font family for the content in this element. (Inherited from TextElement)
Foreground	Gets or sets the Brush to apply to the content in this element. (Inherited from TextElement)
IsAccessKeyScope	Gets or sets a value that indicates whether an element defines its own access key scope. (Inherited from TextElement)
IsTextScaleFactorEnabled	Gets or sets whether automatic text enlargement, to reflect the system text size setting, is enabled. (Inherited from TextElement)
KeyTipHorizontalOffset	Gets or sets a value that indicates how far left or right the keytip is placed in relation to the text element. (Inherited from TextElement)
KeyTipPlacementMode	Gets or sets a value that indicates where the KeyTip is placed in relation to the text element. (Inherited from TextElement)
KeyTipVerticalOffset	Gets or sets a value that indicates how far up or down the keytip is placed in relation to the text element. (Inherited from TextElement)
Language	Gets or sets localization/globalization language information that applies to a TextElement. (Inherited from TextElement)
Name	Gets or sets a unique identification for the object. Name can only be set from initial parsing of XAML. (Inherited from TextElement)
Text	Gets or sets the text contents of the Run.
TextDecorations	Gets or sets a value that indicates what decorations are applied to the text. (Inherited from TextElement)
XamlRoot	Gets or sets the XamlRoot in which this element is being viewed. (Inherited from TextElement)

Methods

ClearValue(DependencyProperty)	Clears the local value of a dependency property. (Inherited from DependencyObject)
FindName(String)	Retrieves an object in the object model / runtime object graph by referencing the object's x:Name or Name attribute value. (Inherited from TextElement)
GetAnimationBaseValue(DependencyProperty)	Returns any base value established for a dependency property, which would apply in cases where an animation is not active. (Inherited from DependencyObject)
GetValue(DependencyProperty)	Returns the current effective value of a dependency property from a DependencyObject. (Inherited from DependencyObject)
OnDisconnectVisualChildren()	Override this method to implement how layout and logic should behave when items are removed from a class-specific content or child property. (Inherited from TextElement)
ReadLocalValue(DependencyProperty)	Returns the local value of a dependency property, if a local value is set. (Inherited from DependencyObject)
RegisterPropertyChangedCallback(DependencyProperty, DependencyPropertyChangedCallback)	Registers a notification function for listening to changes to a specific DependencyProperty on this DependencyObject instance. (Inherited from DependencyObject)
SetValue(DependencyProperty, Object)	Sets the local value of a dependency property on a DependencyObject. (Inherited from DependencyObject)
UnregisterPropertyChangedCallback(DependencyProperty, Int64)	Cancels a change notification that was previously registered by calling RegisterPropertyChangedCallback. (Inherited from DependencyObject)

Events

AccessKeyDisplayDismissed	Occurs when the access key sequence is complete to notify controls that they should hide access key visuals. (Inherited from TextElement)
AccessKeyDisplayRequested	Occurs when the access key sequence is started to notify controls that they should show access key visuals. (Inherited from TextElement)
AccessKeyInvoked	Occurs when a user completes an access key sequence to notify the element that the access key action should be invoked. (Inherited from TextElement)
