Assembly: UIAutomationClient (in UIAutomationClient.dll)
Thetype exposes the following members.
|Collapse||Hides all descendant nodes, controls, or content of the AutomationElement.|
|Equals(Object)||Determines whether the specified object is equal to the current object. (Inherited from Object.)|
|Expand||Displays all child nodes, controls, or content of the AutomationElement.|
|Finalize||Frees resources and performs other cleanup operations before the object is reclaimed by garbage collection. (Inherited from BasePattern.)|
|GetHashCode||Serves as the default hash function. (Inherited from Object.)|
|GetType||Gets the Type of the current instance. (Inherited from Object.)|
|MemberwiseClone||Creates a shallow copy of the current Object. (Inherited from Object.)|
|ToString||Returns a string that represents the current object. (Inherited from Object.)|
Aggregate controls—built with child objects that provide the UI for expand/collapse functionality—must support the control pattern while their child elements do not. For example, a combo box control is built with a combination of list box, button, and edit controls, but it is only the parent combo box that must support the .
A menu control, even though an aggregate of individual menu items, is an exception to this rule. The menu items support the control pattern, but the parent menu control does not. A similar exception applies to the tree and tree item controls.
