Returns the first child or descendant element that matches the specified condition.

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

public:
AutomationElement^ FindFirst (
	TreeScope scope, 
	Condition^ condition
)
public AutomationElement FindFirst (
	TreeScope scope, 
	Condition condition
)
public function FindFirst (
	scope : TreeScope, 
	condition : Condition
) : AutomationElement
Not applicable.

Parameters

scope

A bitwise combination of values that specifies the scope of the search.

condition

The object containing the criteria to match.

Return Value

The first element that satisfies the condition, or a null reference (Nothing in Visual Basic) if no match is found.

The scope of the search is relative to the element on which the method is called.

When searching for a top-level window on the desktop, be sure to specify Children in scope, not Descendants. A search through the entire subtree of the desktop could iterate through thousands of items and lead to a stack overflow.

If your client application might try to find elements in its own user interface, you must make all UI Automation calls on a separate thread.

The following example shows how to find a child window from its identifier.
