怎么实现控件背景透明！

[a8744965]

比如我想把Button A放在另一个Button B上面,A可以看到Button B，但是A的功能完全不变，就是背景可以设置透明，如果有图片，图片也可以设置透明度，有人会吗？提供思路就可以！

/// <summary>

/// 设置透明按钮样式

/// </summary>

private void SetBtnStyle(Button btn)

{

    btn.FlatStyle = FlatStyle.Flat;//样式

    btn.ForeColor = Color.Transparent;//前景

    btn.BackColor = Color.Transparent;//去背景

    btn.FlatAppearance.BorderSize = 0;//去边线

    btn.FlatAppearance.MouseOverBackColor = Color.Transparent;//鼠标经过

    btn.FlatAppearance.MouseDownBackColor = Color.Transparent;//鼠标按下

}

private void btn_MouseHover(object sender, EventArgs e)

{

    Button btn = sender as Button;

    btn.FlatAppearance.BorderSize = 1;

}



private void btn_MouseLeave(object sender, EventArgs e)

{

    Button btn = sender as Button;

    btn.FlatAppearance.BorderSize = 0;

}

btn.FlatStyle = FlatStyle.Flat;//样式 ，Button有这个属性？

用透明边缘的png图片做ImgButton的背景图片应该可行吧。

自定义一个控件好了

    public class IconButton : Control
    {
        public IconButton()
        {
            this.SetStyle(ControlStyles.AllPaintingInWmPaint | ControlStyles.OptimizedDoubleBuffer, true);
            this.SetStyle(ControlStyles.SupportsTransparentBackColor, true);
            this.BackColor= Color.Transparent;
        }
     }
