TreeWalker.Normalize Method (AutomationElement, CacheRequest)

 
System_CAPS_noteNote

The .NET API Reference documentation has a new home. Visit the .NET API Browser on docs.microsoft.com to see the new experience.

Retrieves the node itself, if it satisfies the Condition, or the nearest parent or ancestor node that satisfies the Condition, and caches properties and patterns.

Namespace:   System.Windows.Automation
Assembly:  UIAutomationClient (in UIAutomationClient.dll)

public AutomationElement Normalize(
	AutomationElement element,
	CacheRequest request
)

Parameters

element
Type: System.Windows.Automation.AutomationElement

The element from which to start the normalization.

request
Type: System.Windows.Automation.CacheRequest

A cache request object specifying properties and patterns on the returned AutomationElement to cache.

Return Value

Type: System.Windows.Automation.AutomationElement

The nearest AutomationElement in the current view. If the navigation up the ancestor chain reaches the root element, the root element is returned.

The element is normalized by navigating up the ancestor chain in the tree until an element that satisfies the view condition for the TreeWalker object is reached. If the root element is reached, the root element is returned even if it does not satisfy the view condition.

This method is useful for applications that obtain references to UI Automation elements by hit-testing. The application might want to work only with specific types of elements, and can use Normalize to make sure that no matter what element is initially retrieved (for example, when a scroll bar gets the input focus), only the element of interest (such as a content element) is ultimately retrieved.
