Why does enum type always end up with None?

Question

C++ / C#

var h = dgvShedule.HitTest(e.X, e.Y);
            int idx = (h.Type == DataGridViewHitTestType.Cell) ? h.RowIndex : dgvShedule.RowCount - 1;

h.type none how to get rid of it?

Answer 1

you need to check in which coordinates the coordinates are given, screen coordinates or client coordinates
Point.PointToClient(Point)
Point.PointToScreen(Point)
