Collapse the code in VB.net

Hey coders!
Maybe some one can help me with basic organizing issues.
I'm working on a program with Several user controls , custom events blah blah. and as you can imagine, the code is very large.

What I would like to do is tidy up a bit so that my code is easier to navigate. example:

'-----------------------Events----------------------------------- COL1

'---------------The Blah event---------- COL2
Public Class BlahEventArgs()
end class
public event Blah
'---------------end the blah event------ 2

'------------- Event Handlers------------------------------ COL3

'-------handlers for events from icon(custom control------ COL4
'----------------end icon handler------------------------ 4
'-------------- End Event Handlers------------------------- 3
'---------------end events--------------------------------------- 1

I hove the word COL and a number beside it to represent an area that i would like to collapse.
Th corresponding number is to show where i would like it to collapse to; for instance COL1 will collapse to 1.

Any ideas? Help would be so much appreciated. Thank you.
