I'm not sure whether to call this a bug, a feature request, or just me missing something obvious and/or doing something wrong. When I auto-tooltipify a page, and then change an element's title tag via Javascript, I would generally expect RadTooltipManager to use the new, updated title tag when displaying the tooltip. It doesn't seem to, but perhaps I'm doing something wrong. Has anyone else experienced this issue? Is the only workaround the inelegant manual update via RadTooltipManager on the client side?
In case anyone else runs into this issue, this is roughly how I'm currently working around it:
If there's a better way that doesn't involve the creation of two new objects, maybe a setting I should be including on RadTooltipManager or something along those lines, I'd love to hear it - there are situations in which I do this particular call in a loop, and while I can sometimes pre-create the tooltip manager object, that's still extra overhead I'd like to see trimmed down.
Thanks!

| objImage.title=objImage.alt; //objImage being the element in question, currently being altered by other JS |
| var objTTM=$find(strTTM); //My tooltip manager |
| var objTooltip = objTTM.getToolTipByElement(objImage); |
| objTooltip.set_content(objImage.title); |

Hi ADH,
The behavior you report is the expected one because of the way the autotooltipify functionality works. In brief, when the client object of the manager is created if the AutoToolTipify property is set to true, the manager iterates through all the elements with Title/ToolTip set and replaces the tooltips with RadToolTips. What you are doing is that after this code has already been executed you change the tooltip/title and the manager is not "aware" of this and does not affect the change. What you can do is to either update the manager or force it to retooltipify the page again but this is not an effective solution because if you want to change little count of elements it is not needed to iterate through all the elements on the page. That is why I recommend to stick to your solution which is the best for this particular case.
All the best,
