How to draw the bottom and right border of the grid when pixel scrolling is enabled?

//Event Triggering
this.gridControl1.CellDrawn += new GridDrawCellEventHandler(gridControl1_CellDrawn);
 
//Event Customization
private void gridControl1_CellDrawn(object sender, GridDrawCellEventArgs e)
{
    // Draw the bottom border.
    if (e.RowIndex == this.gridControl1.RowCount
        && this.gridControl1.VScrollPixel)
    {
        e.Graphics.DrawLine(new Pen(new SolidBrush(this.gridControl1.GridLineColor), 1.5f)
        { DashStyle = DashStyle.Solid }, e.Bounds.Left, e.Bounds.Bottom - 2, e.Bounds.Right - 1, e.Bounds.Bottom - 2);
    }
 
    //Draw the right border.
    if (e.ColIndex == this.gridControl1.ColCount
        && this.gridControl1.HScrollPixel)
    {
        e.Graphics.DrawLine(new Pen(new SolidBrush(this.gridControl1.GridLineColor), 1.5f)
        { DashStyle = DashStyle.Solid }, e.Bounds.Right - 2, e.Bounds.Top, e.Bounds.Right - 2, e.Bounds.Bottom);
    }
}
