How to track activities when working with datagridview c#?

Question

PostgreSQL

Good afternoon, I am writing the visual part of a program that works with a PostgreSQL database. When you select a table in the "Select a table:" list, its value is displayed in the datagridview. And in order not to make a field where it will be possible to enter SQL queries such as INSERT, UPDATE, DELETE, how can all this be implemented using only a datagridview. Suppose, to change some value, you need to double-click on the desired cell and change it, but how to count this change? Or selected a line, pressed delete and it was deleted from the datagridview and the database is not deleted now either there or there.

Answer 1

List . For example CellValueChanged , an event that fires when the value of a cell changes.

Answer 2

See what events your grid and its cells have. Choose the ones you want and use them.
