Do you do fill a datagrid?

I've got a button that sends an sql query to the database it works but i don't know how to fill the datagrid with the results of that query

Have a look at the DataTable class and see if that helps:

Once you've populated the DataTable instance with the results of your SQL query, it's just a matter of binding the DataGridView instance to that:

Code:

---

MyGridView.DataSource = MyDataTable

---

It will be automatically populated.
