自定义控件 设计界面

[idea_yuye]

自定义控件如何在拖到窗体后，不运行，修改属性就能在设计界面实时显示当前属性对应的样式？我自己自定义的控件不论怎么设置，样式都不发生变化。我想知道要怎么做才能和系统带的控件一样随属性变化而在设计界面实时显示相应样式。

我的自定义控件代码如下，求大神指定下：

        #region 属性
        private bool IsPress = false;
        private Color borderColor = Color.Black;
        /// <summary>
        /// 边框颜色
        /// </summary>
        public Color BorderColor
        {
            get { return borderColor; }
            set {
                borderColor = value;
                Invalidate();
            }
        }
        private int borderSize = 1;
        /// <summary>
        /// 边框大小
        /// </summary>
        public int BorderSize
        {
            get { return borderSize; }
            set { 
                borderSize = value;
                Invalidate();
            }
        }
        private int roundCornerSize = 0;
        /// <summary>
        /// 圆角大小
        /// </summary>
        public int RoundCornerSize
        {
            get { return roundCornerSize; }
            set { 
                roundCornerSize = value;
                Invalidate();
            }
        }

        private Color impressBackColor = Color.Black;
        /// <summary>
        /// 点击下颜色
        /// </summary>
        public Color ImpressBackColor
        {
            get {
                return impressBackColor; 
            }
            set {
                impressBackColor = value;
            }
        }
        private Color impressForeColor = Color.Black;
        /// <summary>
        /// 点击下前景色
        /// </summary>
        public Color ImpressForeColor
        {

自己顶下 还有大神有别的看法啊？

g.Dispose(); 用完之后不释放掉，会出现一些意想不到的错误

楼主上面的方法不行的？我已经复制你的代码测试过了，没问题的
