Wrap your control in question with a span tag, then target THAT with rad tooltip control. Keep all the enable, disable, etc logic tied to the control in question. The paragraph tag will never be disabled, and will never have the event fire/not fire issue.
Telerik - This would probably be a safe and easy solution for you to implement for the radToolTip control itself. Simply manipulate the DOM with a span around the 'target id' value and key off that instead of the targeted control.
