XAML Values

oneOrMoreInlines

One or more elements that derive from the Inline type. Elements declared here become items in the Span::Inlines collection.

mixedContent

A mixture of inner text and elements that derive from the Inline type. See Remarks.

The Span type exposes the following members.

  NameDescription
Public methodSpanInitializes a new instance of the Span class.

Public propertyContentEndGets a TextPointer that represents the end of the content in the element. (Inherited from TextElement.)
Public propertyContentStartGets a TextPointer that represents the start of content in the element. (Inherited from TextElement.)
Public propertyDispatcherGets the Dispatcher this object is associated with. (Inherited from DependencyObject.)
Public propertyElementEndGets a TextPointer that represents the position just after the end of the element. (Inherited from TextElement.)
Public propertyElementStartGets a TextPointer that represents the position just before the start of the element. (Inherited from TextElement.)
Public propertyFontFamilyGets or sets the preferred top-level font family for the content of the element. (Inherited from TextElement.)
Public propertyFontSizeGets or sets the font size for the content of the element. (Inherited from TextElement.)
Public propertyFontStretchGets or sets the glyph width of the font in a family to select. (Inherited from TextElement.)
Public propertyFontStyleGets or sets the font style for the content in this element. (Inherited from TextElement.)
Public propertyFontWeightGets or sets the top-level font weight to select from the font family for the content in this element. (Inherited from TextElement.)
Public propertyForegroundGets or sets the Brush to apply to the content in this element. (Inherited from TextElement.)
Public propertyInlinesGets an InlineCollection containing the top-level inline elements that include the contents of Span.
Public propertyLanguageGets or sets the language of the content within an TextElement element. (Inherited from TextElement.)

Public methodEquals(Object)Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
Public methodFindNameGets an object in the Windows Phone object model by referencing the object's x:Name or Name attribute value. (Inherited from TextElement.)
Public methodGetAnimationBaseValueReturns any base value established for a Windows Phone dependency property, which would apply in cases where an animation is not active. (Inherited from DependencyObject.)
Public methodGetHashCodeServes as a hash function for a particular type. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Public methodGetValueReturns the current effective value of a dependency property from a DependencyObject. (Inherited from DependencyObject.)

The Span element is used to group other inline content elements. No inherent rendering is applied to content or other elements within a Span element. This means that content is not formatted if it is put inside a Span element without any attributes. However, elements that inherit from Span, such as Hyperlink, Bold, Italic, and Underline apply formatting to text.

Child elements that are contained in a Span element must derive from Inline. The following are the valid child elements:

Mixed Content in XAML

The Span class supports a content model that allows you to mix text and Inline elements in its XAML content. An implicit Run element is created for each block of text. Then, both the Run and Inline elements are added to the Span::Inlines collection. Mixed content is not permitted in most other XAML content models. However, you can use mixed content in Paragraph, Span, and TextBlock.

Supported in: 8.1, 8.0, 7.1
