C Sharp :: No Definition For Fill (WinForms)

I'm working on a personal project, where I have a database (SQLite) and a dataGridView. Now This is what I have:

 public Form1() {
            DataSet ds = new DataSet();
            SqlConnection connection = new SqlConnection(@"Data Source=testingsql2.s3db");
            SqlDataAdapter SQLda = new SqlDataAdapter("Select * from User", connection);
            SqlCommandBuilder SQLcb = new SqlCommandBuilder(SQLda);
            dataGridView1.Fill(ds, "User"); //Error here
            dataGridView1.DataSource = ds;
            dataGridView1.DataMember = "User";
        }

I've marked where I get the error.

And the Error description:
Error    1    'System.Windows.Forms.DataGridView' does not contain a definition for 'Fill' and no extension method 
'Fill' accepting a first argument of type 'System.Windows.Forms.DataGridView' could be found 
(are you missing a using directive or an assembly reference?)
