如何修改 vb.net 中禁用按钮的外观？
我在 vb.net 中禁用了一个按钮，当我这样做时，我无法控制 BackColor 或 ForeColor 属性来更改外观。我为它们设置了新值，但它们没有被采纳。禁用按钮看起来几乎与我的启用按钮一模一样，因此您无法分辨出区别。我正在使用平面样式按钮，但尝试更改它，但它似乎仍然不起作用。有什么技巧可以做到这一点吗？
I'm disabling a button in vb.net and when I do, I cannot control the BackColor or ForeColor properties to change the appearance. I set new values for them but they don't get picked up. The disabled button looks almost exactly like my enabled buttons so you can't tell the difference. I'm using Flat Style buttons, but have tried changing this and it still doesn't seem to work. Is there some sort of trick to be able to do this?

我在 VB.NET 2008 中遇到了类似的问题。
当我在设计时将文本框的背景颜色设置为默认值以外的颜色时，当我在运行时禁用该文本框时，它并没有得到“禁用”的外观；背景颜色保持不变。
为了解决这个问题，我必须重写 OnEnabledChanged 方法并手动将背景设置为我需要的。
这与您遇到的问题有点不同，但我认为重写 OnEnabledChanged 方法可能会帮助您解决问题。
I ran into a similar problem in VB.NET 2008.
When I set the background color of a textbox to something other than the default at design time, then when I disabled that textbox at runtime, it did not get that 'disabled' look; the background color remained unchanged.
To get around this, I had to override the OnEnabledChanged method and manually set the background to what I needed.
This is a little different than the problem you have, but I think that overriding the OnEnabledChanged method might help you out.
