Hello Wendy,
You can hide check boxes for parent nodes by handling the CustomDrawNodeCheckBox event. In this event, you need to manually paint tree lines instead of check boxes for specific nodes. See the code below:
private void treeList1_CustomDrawNodeCheckBox(object sender, DevExpress.XtraTreeList.CustomDrawNodeCheckBoxEventArgs e) {
    if (e.Node.HasChildren) {
        DevExpress.XtraTreeList.ViewInfo.IndentInfo ii = treeList1.ViewInfo.RowsInfo[e.Node].IndentInfo;
        int x2 = e.Bounds.Left + ii.LevelWidth/2;
        int y2 = e.Bounds.Top + e.Bounds.Height/2;
        int h2 = e.Bounds.Height / 2 + 1;
        Rectangle r1 = new Rectangle(e.Bounds.Left, y2, e.Bounds.Width, 1);
        Rectangle r2 = new Rectangle(x2, y2, 1, h2);
        e.Graphics.FillRectangle(treeList1.ViewInfo.RC.TreeLineBrush, r1);
        if (e.Node.Expanded) {
            e.Graphics.FillRectangle(treeList1.ViewInfo.RC.TreeLineBrush, r2);
        }
        e.Handled = true;
    }
}
Thank you, Alex.
