The ExpandCollapsePattern type exposes the following members.
| Name | Description | |
|---|---|---|
![]() | 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 a hash function for a particular type. (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.) |
| Name | Description | |
|---|---|---|
![]() ![]() | ExpandCollapseStateProperty | Identifies the ExpandCollapseState property. |
![]() ![]() | Pattern | Identifies the ExpandCollapsePattern control pattern. |
Aggregate controls—built with child objects that provide the UI for expand/collapse functionality—must support the ExpandCollapsePattern 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 ExpandCollapsePattern.

|---|
A menu control, even though an aggregate of individual menu items, is an exception to this rule. The menu items support the ExpandCollapsePattern control pattern, but the parent menu control does not. A similar exception applies to the tree and tree item controls. |
