You can try with this code

 var connetionString = "..";
    using (var connection = new SqlConnection(connetionString))
    {       

     using(var command = new SqlCommand("SELECT COLUMN1, COLUMN2 FROM YOURTABLE", connection))
     { 
       connection.Open();
       var  dr = cmmand.ExecuteReader();
       if (dr.HasRows == false)
       {
         throw new Exception();
       }
       if (dr.Read())
       {

           textBox1.Text = dr[0].ToString();
           textBox2.Text = dr[1].ToString();
       }

     } 

}
