Tooltip not working in a asp label I have?

Hi all for some reason my tooltip is not working in a ASP label I have.  I am creating it dynamically in a grid header row.  Here is the source of the label that rendered.  Any idea why its not showing?  The label is showing.

<asp:label id='partname' tooltip='Donations White Glove 1-Sided One Sheet'>Donations White Glov...</asp:label>

this is in a table column

Not every control is capable of showing tool tips. Look at the HTML generated for your control and then check HTML specs if that HTML tag can display tool tip or not. And label probably is not one of them.
If you want to show tool tip of every kind of control, you can handle onmousemove client side event and then display tips using some external means. Here is one control that does it..
