Where u.UsrKey like '%'+'" + DropDownList2.Text.Trim() + "'+'%'
แก้เป็น
Where u.UsrKey like '%" + DropDownList2.Text.Trim() + "%'
หรือ
Where u.UsrKey like concat('%','" + DropDownList2.Text.Trim() + "','%')
ผมไม่แน่ใจว่า mssql server เวอร์ชั่นไหน เลยนิยมที่ต่อ string ด้วยคำสั่ง concat แม้จะต่าง type ก็ไม่ error
