更改面板的背景颜色会更改所有面板的背景颜色

Question

我有一个自定义控件OrderEntryCtl，它有一个TableLayoutPanel，它使用第一行单元格中的Panels（称之为标题行，Panels命名为HeaderPanel1，HeaderPanel2等[共8个面板，每列1个）在TableLayoutPanel的第0行中）。每个面板的BackColor首先设置为蓝色。在某些时候，我想将每个Panel的BackColor更改为灰色。这是我遇到的问题：更改1面板的BackColor实际上更改了添加到窗体的所有OrderEntryCtl上所有面板的BackColor。 仅供参考：我没有动态创建任何面板;它们都是通过设计器创建的，VS创建的代码在OrderEntryCtl.Designer.cs中

所以，考虑一下，我的表单上有一些OrderEntryCtl（这些是在我的代码运行时以编程方式/动态添加的，而不是由设计者添加的）。用户与第一个OrderEntryCtl交互（称之为OrderEntry1），然后单击作为控件一部分的按钮。该按钮的click事件处理程序需要将8 HeaderPanel变为灰色：

HeaderPanel1.BackColor = Color.DarkGray;
HeaderPanel2.BackColor = Color.DarkGray;
HeaderPanel3.BackColor = Color.DarkGray;
//etc

我期望只有8个标题面板为OrderEntry1变为灰色，但是，所有OrderEntryCtl的所有标题面板都变为灰色。真奇怪的是，我可以注释掉最后7个“HeaderPanel＃.BackColor = Color.DarkGray;”命令，只留下HeaderPanel1.BackColor = Color.DarkGray;这仍然会发生。但是，如果我添加到事件处理程序

HeaderPanel2.BorderStyle = System.Windows.Forms.BorderStyle.Fixed3D;

只有OrderEntry1的面板2的边框样式受到影响，这是预期的行为！ 如何使BackColor属性的行为与我的面板的BorderStyle属性相同？

在回复第一条评论时，我已将代码包含在Designer.cs

中

好的，在回顾了上述内容之后，我意识到我的问题是我将BackColor属性与我的配置文件中定义的颜色相关联，而我正在为所有面板执行此操作。绑定用于属性更改事件，因此更改1面板上的属性，更新所有面板。

所以，我现在正在讨论如何仍然从我的配置文件中获取我的初始颜色，但没有绑定OnPropertyChange事件？ ？ ？任何人？
