Question about row number when delete Row in listview

Perhaps a bind after remove should do it.

Thank you for Rahul Rajat Singh now and Sarvesh Kumar Gupta I've fix for my problem by apply from your solution

This's my code when MouseDoubleclick Event will Delete Row and Sort Row number again

Hope this code help for another who have same question

private void listView1_MouseDoubleClick(object sender, MouseEventArgs e)
       {
           DataTable dt1 = new DataTable();//<< datatable เปล่า
           string[] data_new = new string[7];//<< ตาม column
           int countnum = 0;
           dt1.Columns.Add("No.", typeof(string));
           dt1.Columns.Add("ID", typeof(string));
           dt1.Columns.Add("NAME", typeof(string));
           dt1.Columns.Add("Price", typeof(string));
           dt1.Columns.Add("Quantity", typeof(string));
           dt1.Columns.Add("Summary", typeof(string));
           dt1.Columns.Add("Lot.", typeof(string));

           for (int i = 0; i < listView1.Items.Count; i++)
           {
               if (listView1.Items[i].Selected == false) //<< inverse Select
               {
                   countnum += 1;
                   data_new[0] = (countnum).ToString();
                   data_new[1] = listView1.Items[i].SubItems[1].Text;

                   dt1.Rows.Add(data_new); //datatabel ใหม่ที่ลบแล้ว
