Question

使用.NET和WinForms创建可滚动的用户控件时，我反复遇到过这样的情况：例如，弹出一个垂直滚动条，重叠控件的内容，导致还需要一个水平滚动条。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让我的控件远离最右边的40像素左右，以便垂直滚动条占用。由于这仍然是控件的有效客户端空间，因此当垂直滚动条覆盖时，水平滚动条仍会出现，即使根本没有隐藏任何控件。但至少用户实际上并不需要使用出现的水平滚动条。

有没有更好的方法让这一切都有效？有哪些方法可以防止不需要的和不需要的滚动条显示出来？

Answer 1

您需要稍微调整控件以适应垂直滚动条的宽度。通过对接实现这一目标的一种方法。而不是仅仅删除表单上的控件，你将不得不玩面板，填充，最小/最大尺寸和对接。

以下是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窗体大小，您将看到未显示水平滚动条且字段不重叠。我还给了字段一个最大宽度以便测量：

    /// Required method for Designer support - do not modify
    /// the contents of this method with the code editor.
    /// </summary>

Answer 2

如果您的控件位于面板内，请尝试将Panel的AutoScroll属性设置为False。这将隐藏滚动条。我希望这能指出你正确的方向。

myPanel.AutoScroll = False

如何确保滚动条不与内容重叠？
