Showing Popup Menus

Popup menus can be used in a number of ways. They can be displayed automatically as a result of end-user's actions, or you can implement your own logic and show popup menus manually. See below to learn more.

Note

Before customizing and using a popup menu, add a BarManager or RibbonControl to the form and ensure that the popup menu is bound to this BarManager/RibbonControl. By default, a popup menu being added to the form at design time automatically looks for a BarManager/Ribbon Control within the form, and if it's found, binds itself to the located object via the PopupMenuBase.Manager/PopupMenuBase.Ribbon property. When creating the menu at runtime, you may need to manually bind it to a BarManager/Ribbon Control via these properties.

Expanded Automatic Display for Controls

It's possible to associate a popup menu with a control and automatically display this menu when an end-user right-clicks the control. To assign a menu to a control, use the control's external PopupContextMenu property. The external PopupContextMenu properties are added at design time for all controls within a form when you place a BarManager or RibbonControl component onto this form.

Add a popup menu to the form. Then, select a control and switch to the Properties window. Locate the external PopupContextMenu property and assign the popup menu to this property.

The menu assigned will be displayed at runtime when right-clicking within the control's bounds.

Note that the external PopupContextMenu property is available only at design time. To associate a menu with a control via code, you can use the BarManager.SetPopupContextMenu method. Call BarManager.GetPopupContextMenu to retrieve the control's popup menu.

Example

Show Me

A complete sample project is available in the DevExpress Code Examples database at http://www.devexpress.com/example=T602283.

This example creates a PopupMenu with three items and binds this menu to the form. You can right-click the form at runtime to invoke the menu.

Expanded Manual Display

To activate popup menus, you normally handle specific events. For instance, if you need to open a popup menu when an end-user right-clicks within a text box, you may want to handle the control's MouseUp event. To open a menu, call PopupMenu.ShowPopup.

Expanded Example

The following code displays a specific PopupMenu if the right mouse button is pressed:

Expanded Automatic Display for Bar Button Items

You can associate a dropdown control (including a PopupMenu object) with regular and large bar button items (BarButtonItem or BarLargeButtonItem). In this instance, this item displays a dropdown arrow and clicking this arrow shows the associated dropdown control below the item:

To associate a popup menu with a bar button item, use the BarButtonItem.DropDownControl property. In addition, the bar item's BarButtonItem.ButtonStyle property must be set to BarButtonStyle.DropDown.
