Hi I want to change the selected listview item but i have encountered with some problem. The color of the selected row wont change. Below are my codes,

            foreach(ListViewItem li in ScheduleListView.Items)

            {

                if (dayDiff > 10)

                {

                    li.Background = Brushes.Green;

                }

                else if (dayDiff < 10 && newDiff > 3)

                {

试试这个：

Try this:

private void FormPatient_Load(object sender, EventArgs e)
{
	lv.OwnerDraw = true;
}

private void lv_DrawItem(object sender, DrawListViewItemEventArgs e)
{
	if (e.Item.Selected)
	{
		lvix.BackColor = Color.Maroon;
		lvix.ForeColor = Color.White;
	}
	else
	{
		lvix.BackColor = Color.White;
		lvix.ForeColor = Color.Black;
	}

	e.DrawBackground();
	e.DrawText();
}
