Adding CssClass property default to custom checkbox wraps with span tag

    i don't know why but when i set CssClass to a default value in the
    constructor for my checkbox control inherited from CheckBox, the rendered
    html wraps the checkbox with a span tag and puts the class attribute on it.

    I'm wondering why it does this?

    I need to add an onclick javascript event to the checkbox, but when i try to
    add it in AddAttributestoRender, it sticks the onclick call on the span tag.

    what do i need to do ?

    thanks

  2. Hi TS,

    From your description, you're meeting some problems when use the ASP.NET
    checkBox server control(custom control derived from it) ,correct?

    As for the ASP.NET checkbox Server control, it is an encapsulated one which
    doesn't 100% identical to the html checkbox input element. The <Span>
    wrapper tag is used to add some addtional features such as DisplayText, for
    standard html checkbox, it doesn't have "Text" setting. So when you want
    to use clientscript to manipulate the actual underlying html checkbox
    element inside the ASP.NET checkbox server control, you may need to
    manually query the checkbox element inside the <span> tag. Also, one way
    to get the html like checkbox element is to use the CheckBox html server
    control. Here are some web threads also discussing on this:
