Listview Items Checked

Listview Items Checked

  Not sure what exactly you need but here is how I would do that.

  ListView.CheckedListViewItemCollection checkedItems = listView2.CheckedItems;

  foreach (ListViewItem item in checkedItems)

  {

  ..... Type what you need to do with the checked items.

  }

  This will go through the listbox and let you do something to each one that is check one at a time.

  Your best bets are to use either the ItemChecked event which is triggered when an event is checked (but not unchecked) or the ItemCheck event which is triggered when an item's checkbox has changed state (either becoming checked or unchecked).

  Usage of either is as simple as setting up the handlers:

  listView1.ItemChecked += new ItemCheckedEventHandler(listView1_ItemChecked);

  listView1.ItemCheck += new ItemCheckEventHandler(listView1_ItemCheck);

  and then the handling functions:

  void listView1_ItemCheck(object sender, ItemCheckEventArgs e)
  {
  if (e.NewValue == CheckState.Checked)
  {
  //Do work on item
  listView1.Items[e.Index].Text = "Was just checked.";
  }
  }

  void listView1_ItemChecked(object sender, ItemCheckedEventArgs e)

  {

  //Do work on item

  e.Item.Text = "Was just checked.";

  }

  Is this more of what you are looking for

  When it comes to determining which items in a ListView control where the CheckBoxes property is set to true, you can get an array of the indexes with the CheckedIndices and an array of the actual objects with the CheckedItems property of your ListView instance.

  Thanks that answers part -

  I want 'do something' when the box is checked.

  The user may check line 3 - then I do something.

  The user then checks line 5 - then I do something else.
