How to export X & Y coordinates?

You can generate X & Y coordinates of your point features by exporting their attribute data in a CSV format from the ribbon (Layer tab – Export Layer). 

Export from the Datagrid works only for database point layers without an MDC form attached.

Note: In case you’re working with an MDC project, to obtain point coordinates, make sure you include Latitude and Longitude form items in your custom form.
