The Spreadsheet has several types of context (pop-up) menus which are invoked when the user clicks different visual objects. The SpreadsheetControl provides the SpreadsheetControl.PopupMenuShowing event which allows you to customize context menus by adding or removing items.

Context Menus Overview

Menu Type	Appearance	Description
SpreadsheetMenuType.AutoFilter		Specifies a context menu which can be invoked by clicking the AutoFilter drop-down arrow.
SpreadsheetMenuType.Cell		Specifies a context menu which can be invoked by right-clicking any cell in a worksheet.
SpreadsheetMenuType.Chart		Specifies a context menu which can be invoked by right-clicking a chart in a worksheet.
SpreadsheetMenuType.ColumnHeading		Specifies a context menu which can be invoked by right-clicking a column header.
SpreadsheetMenuType.DrawingObjects		Specifies a context menu which can be invoked by right-clicking a drawing object when a worksheet contains several drawing objects, such as pictures or charts.
SpreadsheetMenuType.Picture		Specifies a context menu which can be invoked by right-clicking a picture embedded in a worksheet.
SpreadsheetMenuType.PivotTable		Specifies a context menu which can be invoked by right-clicking any cell in a pivot table.
SpreadsheetMenuType.PivotTableAutoFilter		Specifies a context menu which can be invoked by clicking the AutoFilter drop-down arrow on the row or column label of a pivot table.
SpreadsheetMenuType.RowHeading		Specifies a context menu which can be invoked by right-clicking a row header.
SpreadsheetMenuType.SelectAllButton		Specifies a context menu which can be invoked by right-clicking the Select All button in the upper-left corner of a worksheet.
SpreadsheetMenuType.SheetTab		Specifies a context menu which can be invoked by right-clicking a worksheet tab.

Customizing Context Menus in Code

This example demonstrates how to customize the SpreadsheetControl‘s context menu. In particular, this sample demonstrates how to remove or disable the existing items of the context menu and add new menu items.

Handle the SpreadsheetControl.PopupMenuShowing event to change specific items of the SpreadsheetControl’s popup menu every time it is invoked. The current menu can be accessed via the Menu property of the event parameter.

All context menu types are listed in the SpreadsheetMenuType enumeration. The following code modifies the SpreadsheetMenuType.Cell menu, which can be invoked by right-clicking any cell on a worksheet.

Note

The CommandPopupMenu<T>.EnableMenuItem method does not enable the context menu item if you set the corresponding command’s ICommandUIState.Enabled property to false.
