Property Value

Type	Description
DevExpress.XtraBars.Navigation.ExpandCollapseElementList	The list of elements to be additionally expanded/collapsed.

Remarks

To expand/collapse additional elements in code, add these elements to the ElementsToExpandCollapse list. Each list item identifies an element to be expanded/collapsed and the new expansion state for this element. After your AccordionControl.ExpandStateChanging event handler is complete, the AccordionControl traverses through the ElementsToExpandCollapse list and expands/collapses corresponding elements.

Initially, the ElementsToExpandCollapse list contains a single item, which is the currently processed element (ExpandStateChangingEventArgs.Element).
