Grid supports CRUD operations. This CRUD operations can be configured using editSettings. It also has the following modes to manipulate the datasource.

Normal
Dialog
Batch

In the normal edit mode, when you start editing the currently selected record is changed to edit state. You can edit any row by double clicking it or clicking the toolbar’s Edit button. You can change the row values and save edited data to the data source.

In order to add a new record easily, the grid content always displays a blank "add new row". You can enable this feature by setting the showAddNewRow property of editSettings to true.
