tool tips are generaly done use the Alt or Title attribute of an element and
as such can only contain plain text without any formating.

You may try \n to give a line  break in Javascript.
E.g.
strPopUp = 'Line1';
strPopUp += '\n';
strPopUp += 'Line2';
alert(strPopUp);

Well you can actually format a tool  tip using a htc ( if you want the MS
link let me know) But this is a different tool tip  I am building , I just
wanted to know how to create a new line  in javascript.

I tried that bit it wont work for my string for example:



I have to pass this (following) to my function:



c.Attributes.Add("ONMOUSEOVER", "popup(' Time :" & Time & " Event: " &
Hol & " Venue: " & Venue & " ','LightBlue');")



Now what I am trying to achive is the following result:





Time: TIMEVARIABLE

Event: EVENTVARIABLE

Venue: VENUEVARIABLE



That's where the request comes from with the new line.



Is it possible if yes how, I wasn't sure with your previous example  why you
have " ; " after each line  is that needed if yes why and how do I add it to
my example.

c.Attributes.Add("ONMOUSEOVER", "popup(' Time :" & Time & "\n Event: " &
Hol & "\n Venue: " & Venue & " ','LightBlue');")

That does not work that's what I initially tried when I received all the
posts on\n is for the new line.....?



Any other suggestions, why doesn't the example  below work?

Try using \n\r instead of just \n

It seems to work for me OK.

Try with "\r\n" sequence...............

try with 2 escapes: like

popup('test\\n1123');

when c# find only one scape char, the compiler think that you whant to
renderize with the new line. but if you scape the '\n' with other '\' ,
it will work.
try yhe same with the \r
