当使用.NET和WinForms创建可滚动的用户控件时,我反复遇到以下情况,例如,弹出一个垂直滚动条,与控件的内容重叠,从而也需要一个水平滚动条。 理想情况下,内容将稍微收缩以为垂直滚动条腾出空间。

我当前的解决方案是将控件保持在最右边40像素左右,以使垂直滚动条占据。 由于这仍然是控件的有效客户空间,因此即使没有任何控件被隐藏,水平滚动条在被垂直滚动条覆盖时仍会出现。 但是,至少用户实际上不需要使用出现的水平滚动条。

有没有更好的方法可以使这一切正常? 有什么方法可以防止不必要和不需要的滚动条完全显示?

您将需要稍微调整控件的大小以适应垂直滚动条的宽度。 一种通过对接实现此目的的方法。 您不仅需要在窗体上放置控件,还需要在面板,填充,最小/最大大小调整和停靠上进行一些操作。

这是示例代码,您可以将其放置在空白的新Form1后面。 在设计器或运行时中调整窗体的大小,您将看到未显示水平滚动条,并且字段没有重叠。 我还给了字段一个最大宽度,以方便测量:

如果控件在面板内,请尝试将面板的AutoScroll属性设置为False。 这将隐藏滚动条。 我希望这可以为您指明正确的方向。

myPanel.AutoScroll = False
