Hello Réka,
Please note that this is just one possible integration of both frameworks and it does not cover all functionalities. However, jqxGrid can only be bound to an instance of jqxDataAdapter (which is used to load the data from the source). You may also be interested in the recently added ‘obserableArray’ datatype. You can use it to load many types of widgets, including jqxGrid and jqxComboBox. This way, changes made in the grid will be reflected in the original data, too.
Best Regards,
