    Hidden data in ListBox/ListView items?

    I have a ListBox that is displaying a formatted string based on the
    contents of a DataSet. The purpose of the listbox is for the user to
    select an entry to delete, but I'm not sure how to match the listbox
    entry with the corresponding DataRow.

    The DataRow contains a unique id, but the id is not displayed in the
    formatted string that appears in the listbox. Is there a way to
    associate the id of the DataRow with the Listbox item so I know which
    DataRow id to delete based on which listbox item is selected?

      Simply add another column to the ListView, set it's Visible property to
      False and insert the unique id from the DataRow in that column.

      When the user selects a row in the ListView, parse the content of the hidden
      column and voila.

          I think a better idea is to set the Tag property on the ListViewItem to
          the id of the corresponding DataRow. This way, you don't have to deal with
          extra columns, etc, etc.
