C#

protected void Test_CommandColumnButtonInitialize(object sender, TreeListCommandColumnButtonEventArgs e) {
    if(e.ButtonType == TreeListCommandColumnButtonType.Custom) {
        if(e.NodeKey != null) {
            bool isFolder = (bool)e.GetValue("IsFolder");
            if(!isFolder)
                e.Visible = DevExpress.Utils.DefaultBoolean.False;
        }
    }
}
