The Grid has options to show the context menu when right clicked on it. To enable this feature, you need to define either default or custom item in the contextMenuItems.

To use the context menu, inject the ContextMenu module in the grid.

The default items are in the following table.

`AutoFitAll`	Auto fit all columns.
`Edit`	Edit the current record.
`Delete`	Delete the current record.
`Save`	Save the edited record.
`Cancel`	Cancel the edited state.
`Copy`	Copy the selected records.
`PdfExport`	Export the grid data as Pdf document.
`ExcelExport`	Export the grid data as Excel document.
`CsvExport`	Export the grid data as CSV document.
`Group`	Group the current column.
`Ungroup`	Ungroup the current column.
`SortAscending`	Sort the current column in ascending order.
`SortDescending`	Sort the current column in descending order.
`FirstPage`	Go to the first page.
`PrevPage`	Go to the previous page.
`LastPage`	Go to the last page.

By default, the context menu items will be shown in the Grid using the right mouse click action. Show the context menu items during the left mouse click action using the created and context menu’s beforeOpen events of the Grid.

Using the onclick eventlistener of Grid , you can get the clicked position values and send them to the open method of the context menu in the onclick event of the Grid. Also, we have prevented the default right click action to open the context menu items using the created event of the Grid.

This is demonstrated in the following sample.

You can hide or show an item in context menu for specific area inside of grid by defining the target property.

It is possible to enable or disable the default and custom context menu items in the Grid component. This is achieved by using the enableItems method of the ContextMenu. To enable or disable menu items, set the enable parameter in the enableItems method to true, and vice versa.

In the following sample, the Copy item is enabled or disabled based on some condition (as per the needs of the application) in the rowSelected event of the Grid.
