How to filter a List<> in a DataGridView?

[TMattC]

Ive got a List<myClass> instance added to a DataGridView.DataSource. Now I want to filter this. What is the correct way to do so?

You don't - instead, you use a DataView object, and filter that, having set that as the DataSource. Here's my code for my music player list filter:

    /// <summary>
    /// DataView for files list and select
    /// </summary>
    private DataView dvFiles = new DataView();

        List<Track> tracks = GetTracks();
        tracks.Sort();
        DataTable dt = tracks.ToDataTable();
        dvFiles = new DataView(dt);
        dgvTracks.DataSource = dvFiles;

    /// <summary>
    /// A Filter changed - update the DataView
    /// </summary>
    /// <param name="sender"></param>
    /// <param name="e"></param>
    private void textBoxFilter\_TextChanged(object sender, EventArgs e)
        {
        StringBuilder sb = new StringBuilder();
        AppendFilter(sb, "TrackName", tbTrackFilter.Text, "");
        AppendFilter(sb, "Band", tbBandFilter.Text, " AND ");
        AppendFilter(sb, "Album", tbAlbumFilter.Text, " AND ");
        dvFiles.RowFilter = sb.ToString();
        }

Bad command or file name. Bad, bad command! Sit! Stay! Staaaay...
