I would recommend checking our Grid Demos page for more use-case scenarios of the Grid component. For CRUD operations I would suggest taking closer look at the demos under the Data edition section. There you can see the implementation of CRUD operations of the Grid when it is working in Inline, Batch, and Popup editing modes.
For each demo, there are tabs that show the View and Controller code that implement each of them. Check the provided above links and let me know if you have any additional questions.
