Returns the first child or descendant element that matches the specified condition.
Assembly: UIAutomationClient (in UIAutomationClient.dll)
- Type: System.Windows.Automation.TreeScope
A bitwise combination of values that specifies the scope of the search.
- Type: System.Windows.Automation.Condition
The object containing the criteria to match.
Return ValueType: System.Windows.Automation.AutomationElement
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.
