AccordionControl Class

An advanced hierarchical navigation menu.

Namespace:DevExpress.XtraBars.Navigation
Assembly:DevExpress.XtraBars.v17.2.dll

Expanded Syntax

Expanded Remarks

Accordion Control extends the capabilities of the NavBarControl for creating navigation menus. The control's items can be combined into groups. Groups can contain nested groups so you can create an advanced navigation hierarchy.

Features include:

All elements within the accordion control are AccordionControlElement class objects. Depending on the AccordionControlElement.Style property value, an element is considered as either a group or an item.

An item is an element whose AccordionControlElement.Style property is set to Item. An item can act as a button. You can handle the AccordionControlElementBase.Click or ElementClick event to perform custom actions. You can also associate an expandable custom control container with an item (with the AccordionControlElementBase.ContentContainer property or GetContentContainer event).

A group is an AccordionControlElement object of the Group style. It is an expandable element that can only display items and other groups. The group's child elements are stored in the AccordionControlElement.Elements collection.

According to the AccordionControlElement.Style property, certain properties of elements may be ignored. Properties that are only appropriate for items are ignored for groups, and vice versa. For instance, groups can only display other groups and items, so the ContentContainer property has no effect on groups. Vice versa, items can display a custom content and cannot have child elements; thus the AccordionControlElement.Elements collection is not in effect for items.

The control itself also has the Elements collection, which stores top-level elements.

At design time, items and groups can be added using the control's context menu and smart tags provided by the control and its elements.

You can also use the control's designer to modify the control's element collection, customize appearance, and save and load the control's layout.

See the AccordionControlElement topic to learn more.
