C#-怎么让鼠标移到contextMenuStrip某一行时,背景色变蓝色,坐等
很多软件的托盘图标的右键菜单都有这样的效果,QQ也有,我用了MouseMove和MouseEnter都不行么.......它们都会在鼠标移开后才变颜色,急求~~~

[解决办法]
试了一下
MouseEnter是有效果的
只不过被默认的颜色覆盖了
当你MouseLeave时
默认的颜色没了
所以才出现你设置的颜色

C# code

        Boolean bPaint = false;        private void MenuItemMouseEnter(object sender, EventArgs e)        {            ToolStripMenuItem menuItem = sender as ToolStripMenuItem;            if (menuItem != null)            {                bPaint = true;                menuItem.Invalidate();            }        }        private void MenuItemMouseLeave(object sender, EventArgs e)        {            bPaint = false;         }        private void MenuItemPaint(object sender, PaintEventArgs e)        {            ToolStripMenuItem menuItem = sender as ToolStripMenuItem;            if (menuItem != null)            {                if (bPaint)                {                    e.Graphics.FillRectangle(Brushes.Red, 0, 0, menuItem.Width, menuItem.Height);                    Brush brush = new SolidBrush(Color.Black);                    Font font = new Font(menuItem.Font.Name, menuItem.Font.Size);                    e.Graphics.DrawString(menuItem.Text, menuItem.Font, brush, 20, 2);                }            }        }

用其他控件
Dev，ComponmentOne 等
