Event Data

The PopupMenuShowing event's data class is PopupMenuShowingEventArgs. The following properties provide information specific to this event:

Property	Description
Customizations	Provides access to the collection of context menu customization actions.
Menu	Gets or sets the context menu for which the event is raised.
MenuType	Indicates a spreadsheet element for which the context menu is invoked.

Remarks

Handle the PopupMenuShowing event to modify context menu items.

Use the PopupMenuShowingEventArgs.Customizations property to add or remove items. The PopupMenuShowingEventArgs.MenuType property allows you to determine for which spreadsheet element (a cell, row or column heading, drawing object, etc.) the menu is invoked. To obtain the context menu for which the event is raised, use the PopupMenuShowingEventArgs.Menu property.

The example below customizes the Cell context menu as follows:

• Creates new Merge Cells and Highlight Cells items
• Removes the Insert Comment and Hyperlink items
