Properties

ExpandCollapseState

Gets the state, expanded or collapsed, of the control.

public ExpandCollapseState ExpandCollapseState { get; }

Property Value

ExpandCollapseState

Remarks

public void Expand()

Remarks

Windows	IExpandCollapseProvider.Expand
macOS	Called by setting NSAccessibilityProtocol.setAccessibilityExpanded to true, by calling NSAccessibilityProtocol.accessibilityPerformPress, or by calling NSAccessibilityProtocol.accessibilityPerformShowMenu when ShowsMenu is true.
