I'm trying to add an export-to-csv option to a Highcharts chart, without actually removing all the default options (print, PNG, JPG, PDF, SVG export). The solution offered in Highcharts add export as csv results in the existing options being blown away, as does trying to use the Exporting class in DotNet.Highcharts. Is there a way to achieve this?

NB: I can see how to achieve what I want by editing exporting.js, but that's not a desirable way to go about it :)

You can add the new item to the menu right after you define the chart:

Highcharts.getOptions().exporting.buttons.contextButton.menuItems.push({
    text: 'My new button',
    onclick: function () {
        alert('OK');
    }
});

This will keep the default items.
