customizeContextMenu

customizeContextMenu(customizeFunction: Function)

[starting from version: 2.6]

This API call allows customizing the context menu. For example, you can create a context menu for the flat form or remove all context menu items for the classic form. Learn more in this guide: Customizing the context menu.

customizeContextMenu can be defined in two ways:

1. As a regular API call: flexmonster.customizeContextMenu(customizeFunction: Function).
2. As an initialization parameter: new Flexmonster({customizeContextMenu: customizeFunction, ...}).

Parameters

The customizeFunction function. It has the following signature: customizeFunction(items: ContextMenuItemObject[], data: CellDataObject | CellDataObject[] | ChartDataObject, viewType: String): ContextMenuItemObject[].
Data passed to the customizeFunction:

Parameter/Type	Description
items ContextMenuItemObject[]	Context menu items created by Flexmonster.
data CellDataObject | CellDataObject[] | ChartDataObject	Contains information about the right-clicked element. If a grid cell is right-clicked, the data is a CellDataObject containing information about the cell. If multiple cells are selected and then right-clicked, the data is an array of CellDataObjects. If a chart element is right-clicked, the data is a ChartDataObject containing information about the chart segment.
viewType String	View type that was right-clicked. Can have one of the four possible values: "pivot" - Means that the pivot grid was right-clicked, either the compact or classic form. "flat" - Means that the flat form was right-clicked. "charts" - Means that the chart view was right-clicked. "drillthrough" - Means that drill-through view was right-clicked.

The customizeFunction must return items, the array of new or changed context menu items. If items is null, the default items will be used. If items is [], the context menu will be hidden.

});
