    function selectedColorChanged() {
        document.getElementById("<%=textbox1.ClientID%>").style.color = "#" + document.getElementById("<%=ColorPickerExtender1.ClientID%>").get_selectedColor();
    }

Look at your view source of web page then name within document.getElementById('XXXXXX') should be the name of html control having name XXXXX. If not present you will get this error
