How to save changes from “textbox” to database?

Question

The current entry from "dataGridView1" is displayed in "textBox1".

The user in "textBox1" makes changes.

How to save changes from "textBox" to the database and display in "dataGridView1"?

I enclose the code of my decision.

If the form has several "textBox", "checkBox1", then make an event for each element, somehow troublesome ...

Are there any other more efficient ways to do this?
