อันที่จริงคุณก็เรียก this.TextBox1.Text ได้เลยน่ะครับ ไม่ต้องประกาศ new ขึ้นมาอีกครับ

แก้เป็น
strSQL = "update Customer set Name='" +This.TextBox1.Text + "',SurName='" + This.TextBox2.Text + "',Address ='" + This.TextBox3.Text + "',Email='" + This.TextBox4.Text + "',Phone='" + This.TextBox5.Text + "' where CusID = (select top(1)CusID from Customer order by CusID desc)";
ก็ยังใช้ไม่ได้ครับ Error Objeck referrence not set to an instance of object
