Gets or sets the direction that text and other user interface (UI) elements flow within any parent element that controls their layout.

Public Property FlowDirection As FlowDirection

Property Value

FlowDirection

The direction that text and other UI elements flow within their parent element, as a value of the enumeration. The default value is LeftToRight.

Attributes: LocalizabilityAttribute

Remarks

The dependency property usage sets the FlowDirection on this element. Because of property value inheritance, setting FlowDirection on an element can potentially set FlowDirection on all child elements that did not set FlowDirection locally or though other means such as styles.

This property is not automatically set as part of any application culture information, because an element might contain content that is not necessarily intended to obey the general flow direction implied by the culture information. For more information on globalization considerations, see Globalization for WPF.

This property has a defined common language runtime (CLR) property accessor, so it functions as a dependency property. However, it is also registered as attached, so it can also function as an attached property. The attached registration is mainly so that property value inheritance is supported, but the property can also be used as a true attached property. The attached property usage is only relevant if the object you intend to set the flow direction on has a FrameworkElement parent element that performs layout upon it, is itself not a FrameworkElement, and does not already have a more directly defined FlowDirection property. (Some of the flow document classes such as Block and Inline define their own FlowDirection, and this property can also set the flow direction. The property value is then read by the eventual content host without requiring attached property usage.)

XAML Attribute Usage

<object FlowDirection="FlowDirection"/>

XAML Text Usage

This property can also be set on classes that are not FrameworkElement derived classes by the following XAML attached property usage:

<object FrameworkElement.FlowDirection="FlowDirection"/>
