CartesianChart.MouseMove not firing on .NET6/WinForms

Discussed in #397

^{Originally posted by RodLeyton February 13, 2022}
Win11/WinForms on .NET6.0 using C#10 on VS2022.
I am trying to receive mouse move events, so I can get the X and Y values via CartesianChart.ScaleUIPoint.

I have registered for the event using

CartesianChart.MouseMove += Chart_MouseMove_new;


Chart_MouseMove_new(object? sender, MouseEventArgs? e) 
{   // Breakpoint
   if (e is null) return;
   //........
}

However it does not fire (tested by debug breakpoint).
Also tried MouseClick and MouseDown events, which I couldn't get to fire either.
I could get ChartPointPointerDown to fire successfully, but I really do need the move event.

Are these events supported yet, or am I missing something here?

This is not fixed, take web site article/repo is updated:

https://livecharts.dev/docs/WinForms/2.0.0-rc1/samples.general.scrollable

specially take a look at the `GetDrawnControl() method:

cartesianChart2.GetDrawnControl().MouseMove += CartesianChart2_MouseMove;

I can confirm this fix works now.

[En-JON-eer]

cartesianChart1.GetDrawnControl();
This fixed the issue of handling chart click events.

However,

If I do not call GetDrawnControl();, a tradeoff is made:
I can mouse over data with the tooltip showing all data values seamlessly. TooltipFindingStrategy.CompareAllTakeClosest seems to work beautifully here:

BUT - we cannot pan/zooom/zoom box (right click).

If I call cartesianChart1.GetDrawnControl();,

Pan/zoom/zoom box works fine. But it seems the TooltipFindingStrategy.CompareAllTakeClosest property is lost?

@beto-rodriguez I'm not entirely sure how to re-open this issue.
