Datagridview cell details with tooltip

[Eran.Yasso]

Hi,

I need to display some info attached to a row in Datagridview. I
thought to do it in MouseMove event. The problem is that this event is
continuously fired which causes the tooltip to flicker.

I saw a post of some guy complaining on the same issue (he didn't get
any response).

Any way I can do it?

Thanks,
Eran.

Well, as a thought (untested) for workarounds: you could keep track of
the last x,y position you updated, and if the mouse hasn't moved
simply exit without updating the tool tip? or perhaps use some kind of
timer so that you only set the tooltip after 200ms of mouse
inactivity? something like that?

Hello Marc and thanks for the reply.

Is this the only way I can do it? Why can't I use the ToolTip class in
datagridview?

Ok, found the solution.
If one wishes to use ToolTip() class for Datagridview instead of using
Datagridview built in tooltip, he should set "ShowCellToolTips" to
false.
