Start BoxOver without Title tag

[ElNiNo]

Hi

I am using an asp.net control that generates its html with javascript.
So the different objects inside the control don't have a title tag, because they are not rendered as html in my page.

However they do have clientscript possibilities.
For every item I can define javascript events.

Is it possible to start and stop the boxover from JavaScript without the Title attribute?

<EventMouseOver ClientScript="javascript:BoxOverStart('[header]=testheader[body]=testbody');"/>
<EventMouseOut ClientScript="javascript:BoxOverStop();"/>

Can this be done?

With kind regards
Bavo
