Winforms 同一WinForm上不能有2个抽象派生文本框？

好吧，这是个奇怪的问题。我有一个从TextBox派生的名为Writer的抽象控件，以及从中派生的两个类，StdWriter和LngWriter。它们之间的区别是一个始终是多行的，而另一个则不是。这是两者之间唯一的区别

在OnHandleCreated函数中，我使用Win32 SendMessage函数设置边距。我在OnPaint中再次这样做，因为如果同一表单上有超过1个StdWriter（或任何派生的文本框类型），WinForms将“忘记”设置边距（这也没有意义，但至少我有一个解决方法）

现在我有一个问题，我不能让这两个文本框在同一个表单上。如果我在表单上放置一个StdWriter和一个多行文本框，或者一个LngWriter和一个标准文本框，它就会工作。如果我在表单上放置2个MS文本框，它也可以工作。但是，让我将LngWriter和StdWriter放在一起，LngWriter将不会正确绘制其滚动条（垂直方向是错误的，它只是不会绘制水平方向的句点）或接受ENTER键，尽管MultiLine和AcceptsReturn都返回true。我甚至不能粘贴新行，因为它完全删除了它们

我不明白这一点，因为TextBox是从抽象TextBoxBase派生的，我的表单上有几十个不同的派生文本框，我没有任何问题。是因为我在继承链中插入了第二个抽象类，而VisualStudio不喜欢它还是什么

除非你发布代码，否则我们将无法帮助你…我不得不删除很多属性，因为SO的限制非常小。基本上，文本框包含一个tablelayoutpanel，其中在页边空白处包含一个图标和一个复选框。两个控件都独立工作，所以我不认为这是错误的。我还注意到，如果我使用MultiLine return base.MultiLine而不是true/false，它会无缘无故地返回调用异常。陌生人和陌生人。如果我注释掉除构造函数以外的所有内容，它就可以工作了。第二次重写MultiLine时，即使它只是一个直接传递，它也会中断。好的，看起来它直接从MultiLine getter返回true。显然，我可以直接使用真/假来欺骗二传手，但这对二传手来说是不可能的。世界跆拳道联盟。
