If you can't read my code, try converting it here[^]

using (SqlConnection cnn = new SqlConnection(strConnect))
    {
    cnn.Open();
    using (SqlCommand cmd = new SqlCommand("SELECT * FROM LISTSTAFF()", cnn))
        {
        using (SqlDataAdapter da = new SqlDataAdapter(cmd))
            {
            DataTable dt = new DataTable();
            da.Fill(dt);
            gridview.DataSource = dt;
            }
        }
    }

CREATE PROCEDURE LISTSTAFF
