TreeWalker.Normalize Method (AutomationElement, CacheRequest)

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
public AutomationElement Normalize (
	AutomationElement element, 
	CacheRequest request
public function Normalize (
	element : AutomationElement, 
	request : CacheRequest
) : AutomationElement
Not applicable.



The element from which to start the normalization.


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

Return Value

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.
