Not clean.

If you want add code ( codeToAdd ) to a method ( codeWhereAdd ):
codeWhereAdd = Header.Click
codetoAdd = ????

However, the generic solution is this:
Add a CodeHook property to the Header class.
within the Click write:

* Header Click
*** pre code
....
....
this.ClickHook = .T.
*** post code
....
....

on the program use this:

BINDEVENT(headerRef,"ClickHook",codeToAddObject,"codeToAddMethod")

If this.ClickHook = .T. is at begginnig or at the end of Header.Click
you can skip it and to use:

BINDEVENT(headerRef,"Click",codeToAddObject,"codeToAddMethod")   && execute codeToAddMethod before to header.click
BINDEVENT(headerRef,"Click",codeToAddObject,"codeToAddMethod",1) && execute header.click before to codeToAddMethod
