From what kind of control do you want to get the MouseDown event and x and y positions and what kind of error do you get ?

Best regards.

The EventArgs for the MouseEnter, MouseHover and MouseLeave events do not have any useful information.

The EventArgs for MouseMove, MouseDown, MouseWheel and MouseUp do have X and Y properties.

You must be aware that the MouseEnter, MouseHover and MouseLeave events are only available on the desktop.
You can get the x and y coordinates of the mouse with the MouseMove event after the MouseEnter event.

Attached a small program to play with.

Best regards.

Reasonable when using a stylus whose position can only be detected by the device when it is "down", that is, touching the screen already!

I agree with you, but sometimes the 'most' evident things are overlooked.

Best regards.
