Question

I have:

<script type="text/javascript">

    $(function() {
        var id = '<%=txtEditor.ClientID%>';
        var editor = CodeMirror.fromTextArea(document.getElementById(id), {
            mode: "application/xml",
            lineNumbers: true,
            buttons : ['undo','redo'],
            onCursorActivity: function() {
                editor.setLineClass(hlLine, null);
                hlLine = editor.setLineClass(editor.getCursor().line, "activeline");
            }
        });
        var hlLine = editor.setLineClass(0, "activeline");
    });

</script>

Code works fine but unable to highlight syntax and button is not appear.Am i missing something.Thanks.

There’s is on buttons option in CodeMirror. If things don’t highlight, you probably forgot to include a stylesheet.
