ToolTips on ListView Header

[Yura Moldavanov]

Hello, All!

I have a problem with putting the ToolTips on ListView Header

ToolTip Text Property must changes depending on column, which is under
mosue cursor.

Problem 1. Standatr .Net class TooTip is not shown, when mouse not in the
client area of ListView.
I trying to solve this through Win Api CreateEx function, SendMessage e t.c.
But therein lies a problem for me that I can't to know which column is under
mouse cursor.

Please help me to find optimal solution how to set ToolTip on LiseView
Header, which show the current column Title...

Best Regards

I think I solve this question :)

Can I do it without WINAPI SendMessage () ?

How do you initialize 'headerHandle' ?

headerHandle = (IntPtr)SendMes sage((int)Handl e, LVM_GETHEADER,0 ,0);
