I have a button which is disabled on some cases,

enter image description here

now I want to display a tooltip text when the user moves the mouse over the disabled button, I've tried two events Mouse Hover & Mouse Move, noticed that it won't fire any events for the disabled button.

as per this post, it seems it'll work, but since I have too may controls on my Form, I'm slightly concerned to use this method due to the performance factor.

Is there any better way of handling this issue?? your thoughts on this would be much appreciated, many thanks...:)

    I don't think it will have much affect on your GUI performance. There is a slightly better version posted here. http://stackoverflow.com/questions/1732140/c-problem-displaying-tooltip-over-a-disabled-control – Ehsan Jul 02 '13 at 12:38

    Have you tried the proposed solution? (i.e. have you checked if there really IS a performance problem?) If not try it, and if it works you don't have any problem to solve ;-) – Treb Jul 02 '13 at 12:39
  • Thanks Eshan & Treb, I have tried the above solution & didn't check the performance yet, the target machine would be using XP & it's dual core machine, I was thinking if there's any option like region wise events, just for betterment of my solution?? – SanVEE Jul 02 '13 at 12:47

    @San I don't think thee is any performance issue with the solution from the link you posted. Just a little code in only 1 `MouseMove` event handler for your form, the code just shows or hides the tooltip so there won't any performance issue here. – King King Jul 02 '13 at 13:10
