如何更改DataGridView行的背景颜色并在悬停时撤消？

Question

I think this is simple problem but the following code snippet not worked. If currnet row is green I want it to be lighter green else I want light blue. When I MouseLeave, the colors must become the previous state.

In this code, whatever the color is, it becomes blue. When you move the mouse, it becomes white. It seems to be working fine in debug mode (entering if statement).

 private void dtgVeri_CellMouseMove(object sender, DataGridViewCellMouseEventArgs e)
    {
        if (e.RowIndex == -1) return;

        Color colorToChange=Color.LightBlue;
        Color colorCurrent = dtgVeri.Rows[e.RowIndex].DefaultCellStyle.BackColor;

        if (colorCurrent == Color.LightGreen)
            colorToChange = Color.PaleGreen;

        dtgVeri.Rows[e.RowIndex].DefaultCellStyle.BackColor = colorToChange;
    }

    private void dtgVeri_CellMouseLeave(object sender, DataGridViewCellEventArgs e)
    {
        if (e.RowIndex == -1) return;

        Color colorToChange = Color.White;
        Color colorCurrent = dtgVeri.Rows[e.RowIndex].DefaultCellStyle.BackColor;

        if (colorCurrent == Color.PaleGreen)
            colorToChange = Color.LightGreen;

        dtgVeri.Rows[e.RowIndex].DefaultCellStyle.BackColor = colorToChange;
    }

Solved problem using CellMouseEnter event instead of CellMouseMove . Because CellMouseMove is constantly checking and creating problems but we want control only once hover at Enter and Leave.
