c#如何改变listview item背景颜色?
问题补充：private void listView1_MouseHover(object sender, EventArgs e)
        {        }当有事件mouse经过的时候，然后如何来改变他的item的backgroud.

Answer 1

鼠标经过没有做过,下面是改变已选择项背景色的代码        private void  ItemSelectionChanged(object sender, ListViewItemSelectionChangedEventArgs e)
        {
            if (e.IsSelected == true)
            {
                foreach (ListViewItem.ListViewSubItem lvi in e.Item.SubItems)
                {
                    lvi.BackColor = Color.Silver;
                }
            }
            else
            {
                foreach (ListViewItem.ListViewSubItem lvi in e.Item.SubItems)
                {
                    lvi.BackColor = Color.White;
                }
            }
        }

Answer 2

listView1.Items[0].BackColor = Color.Red

Answer 3

长时间悬停时原本就不会触发MouseHover
protected   override   void   OnMouseHover(EventArgs   e) 
{ 
}
void listView1_LostFocus(object sender, EventArgs e)
        {
            foreach (ListViewItem item in listView1.SelectedItems)
            {
                item.Tag = item.BackColor;
                item.BackColor = Color.YellowGreen;
            }
        }

Answer 4

提供一个低效的办法:
 private void listView1_MouseMove(object sender, MouseEventArgs e)
        {
                       
            ListViewItem item = this.listView1.GetItemAt(e.X, e.Y);
            if (item != null)
            {
                foreach (ListViewItem i in this.listView1.Items)
                {
                    if (i == item)
                        i.BackColor = Color.Red;
                    else
                        i.BackColor = Color.White;
                }
            }
            else
            {
                foreach (ListViewItem i in this.listView1.Items)
                    i.BackColor = Color.White;
               
            }
        }

Answer 5

  private void listView1_ItemMouseHover(object sender, ListViewItemMouseHoverEventArgs e)
        {
            e.Item.BackColor = Color.Red;
        }    

Answer 6

怎么很多人 没注意到这个事件的。listView1_ItemMouseHover

Answer 7

主要是很少办这种无聊的事.
如果有非常多的Item的话,怎么操作也是非常低效的.因为在改变一个项的颜色时,必须修改其他项的颜色.
