在使用 .NET 和 WinForms 创建可滚动的用户控件时,我反复遇到过以下情况,例如,弹出垂直滚动条,与控件的内容重叠,导致还需要水平滚动条。理想情况下,内容会缩小一点,以便为垂直滚动条腾出空间。

我目前的解决方案是将我的控件保持在最右边的 40 像素之外,这样垂直滚动条就会占据上去。由于这仍然是控件的有效客户端空间,因此当水平滚动条被垂直滚动条覆盖时,它仍然会出现,即使根本没有隐藏任何控件。但是至少用户实际上不需要使用出现的水平滚动条。

有没有更好的方法来使这一切正常工作?有什么方法可以完全防止不需要和不需要的滚动条出现?

您需要稍微调整控件的大小以适应垂直滚动条的宽度。实现这一点的一种方法是通过对接来实现。您不仅要在表单上放置控件,还需要在面板、填充、最小/最大尺寸和停靠方面进行一些操作。

这是您可以放置​​在空白的新 Form1 后面的示例代码。在设计器或运行时调整表单大小,您将看到水平滚动条未显示且字段未重叠。我还为这些字段设置了最大宽度,以便更好地衡量:

如果您的控件位于面板内,请尝试将面板的 AutoScroll 属性设置为 False。这将隐藏滚动条。我希望这能为您指明正确的方向。

myPanel.AutoScroll = False
