Question

I am attempting to scroll through a database of Album Names using ListView. When I initially select an album, _SelectedIndexChanged returns the appropriate album; however in subsequent attempts to select an album, ListView returns a System.ArgumentOutOfRangeException – InvalidArgument=Value of ‘0’ is not valid for ‘index’. Could someone please steer me in the right direction as to what can be done to avoid this error?

private void ScrollThroughAlbums()
    {
      string selectStatement = "SELECT * FROM Albums ORDER BY Artist";
      OleDbCommand selectCommand = new OleDbCommand(selectStatement, oleDatabaseConnectionString);
      OleDbDataReader myReader = selectCommand.ExecuteReader();
      ColumnHeader columnHeader1 = new ColumnHeader();
      ColumnHeader columnHeader2 = new ColumnHeader();
      ColumnHeader columnHeader3 = new ColumnHeader();

      columnHeader1.Text = "Album";
      columnHeader2.Text = "Artist";
      columnHeader3.Text = "Tracks";

      listView1.Columns.Add(columnHeader1);
      listView1.Columns.Add(columnHeader2);
      listView1.Columns.Add(columnHeader3);
      listView1.Columns[0].Width=130;
      listView1.Columns[1].Width=130;

      listView1.View = View.Details;
      listView1.AllowColumnReorder=true;
      listView1.FullRowSelect=true;
      listView1.GridLines=true;
      listView1.MultiSelect = false;
      listView1.Sorting= SortOrder.Ascending;

      while (myReader.Read())
      {
         string frontCoverXML = myReader.GetString(3).ToString();
         string Artist = myReader.GetString(1).ToString();
         string Album = myReader.GetString(2).ToString();
         string TracksXML = myReader.GetString(4).ToString();
         ListViewItem item = new ListViewItem(new []{Album,Artist}); 
         listView1.Items.Add(item); 

        } myReader.NextResult();
        myReader.Close();
    }

   private void listView1_SelectedIndexChanged(object sender,EventArgs e)
   {
      ListView.SelectedListViewItemCollection album = this.listView1.SelectedItems;
      MessageBox.Show(album[0].ToString());
   }

Answer 1

   private void listView1_SelectedIndexChanged(object sender,EventArgs e)
   {
      ListView.SelectedListViewItemCollection album = this.listView1.SelectedItems;
      if(album.Count>0)
         MessageBox.Show(album[0].ToString());
   }
