06 Oct 2022 / 4 minutes to read

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.

Show context menu on left click

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.
