ASPxClientSpreadsheetPopupMenuItemCollection.Add(item) Method

Adds the specified menu item to the end of the collection.


    item: ASPxClientSpreadsheetPopupMenuItem
): void


Name Type Description
item ASPxClientSpreadsheetPopupMenuItem

An ASPxClientSpreadsheetPopupMenuItem object specifying the item to be added to the collection.


This sample illustrates how to prevent the context menu display for worksheet tabs and to add a custom menu item to the context menu displayed for row headings.

The context menu is dynamically processed in the ASPxClientSpreadsheet.PopupMenuShowing client event. The current context menu type is determined through the ASPxClientSpreadsheetPopupMenuShowingEventArgs.menuType property. A custom menu item is implemented as a new item containing a custom command name.

Clicks on the custom menu item with the custom command name are processed by using the ASPxClientSpreadsheet.CustomCommandExecuted client event. Within its handler, the activated custom command is identified and the corresponding action (insertion of a row with the current date and time values) is performed through a callback to the server.
