extended gridview with insert,update,delete,add,sorting,

hi need code for extended ...
It does not work like this here.

Here is what is expected of enquirers:
1. TRY first what you want to do!
2. Formulate what was done by you that looks like an issue/not working.

Try them and tell if you face issues.
Members will be more than happy to help like this.

For now, have a look at these and learn:
GridView all in one[^]
Editable Nested GridView (All-in-One)[^]
Inplace Edit in GridView[^]
