WinForms TreeList - Dynamic node loading in unbound mode

This example displays your local file-folder structure in the WinForms TreeList control. The example implements dynamic node loading in unbound mode:

private void treeList1_BeforeExpand(object sender, DevExpress.XtraTreeList.BeforeExpandEventArgs e) {
    if (e.Node.Tag != null) {
        Cursor currentCursor = Cursor.Current;
        Cursor.Current = Cursors.WaitCursor;
        InitFolders(e.Node.GetDisplayText("FullName"), e.Node);
        e.Node.Tag = null;
        Cursor.Current = currentCursor;
    }
}
