1. Add check box: Listview1.checkboxes = true;



2. Select the ListView and get the selected number:





[CSharp]View PlainCopy
    1. Private void listview1_itemchecked (object sender, Itemcheckedeventargs e)
    2. {
    3. e.item.selected = e.item.checked;
    4. m = ListView1.CheckedItems.Count;
    5. Label1.  Text = "Current number of selected:" + m.tostring ();
    6. }


Note: Click the checkbox or double-click the ListView to select a row, but unlike the ComboBox control, get the selected number to use:m = listView1.CheckedItems.Count; And not listView1.SelectedItems.Count;!!!!!!!!!



3. Get multiple values selected in the check box in the ListView





[CSharp]View PlainCopy
  1. int k = 0;
  2. int m = ListView1.CheckedItems.Count;
  3. String[] A = new string[m];
  4. queue<string> Q = new queue<string> ();
  5. for (int i = 0; i < m; i++)
  6. if (Listview1.checkeditems[i]. Checked)
  7. Q.enqueue (Listview1.checkeditems[i]. SUBITEMS[1]. Text);
  8. while (Q.count > 0)
  9. {
  10. A[k] = Q.dequeue ();
  11. k++;
  12. }
