ใช้ LINQ บรรทัดเดียวน่าจะตอบโจทย์ได้แล้วครับ
ประมาณนี้ var x = yourListViewName.Cast<ListViewItem> Group x Count y

ขอบคุณครับ โค้ดที่ให้มาถือว่าเป็นของขวัญปีใหม่ที่มีค่าสำหรับผมมากครับ เพราะผมจะนำไปศึกษาเรื่องการ User Control และการ
Customize Control ที่มีอยู่แล้วให้น่าใช้ขึ้นครับผม เพราะผมมีปัญหากลับ DataGridView มากมาก (มันไม่สวย) คือต้องการให้มันเหมือน
Table ของ HTML ครับผม ขอบคุณครับ
