.net 如何确保滚动条不';不重叠内容?
在使用.NET和WinForms创建可滚动用户控件时,我多次遇到这样的情况:例如,弹出一个垂直滚动条,与控件的内容重叠,导致还需要一个水平滚动条。理想情况下,内容会缩小一点,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像素左右,这样垂直滚动条就会占据空间。因为这仍然是控件的有效客户端空间,所以当水平滚动条被垂直滚动条覆盖时,水平滚动条仍然会出现,即使根本没有隐藏任何控件。但至少用户实际上不需要使用弹出的水平滚动条.net 如何确保滚动条不';不重叠内容?,.net,winforms,.net,Winforms,在使用.NET和WinForms创建可滚动用户控件时,我多次遇到这样的情况:例如,弹出一个垂直滚动条,与控件的内容重叠,导致还需要一个水平滚动条。理想情况下,内容会缩小一点,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像素左右,这样垂直滚动条就会占据空间。因为这仍然是控件的有效客户端空间,所以当水平滚动条被垂直滚动条覆盖时,水平滚动条仍然会出现,即使根本没有隐藏任何控件。但至少用户实际上不需要使用弹出的水平滚动条 有没有更好的办法让这一切顺利进行?有什么方法可以防止不需要
有没有更好的办法让这一切顺利进行?有什么方法可以防止不需要或不需要的滚动条出现?如果控件位于面板内,请尝试将面板的AutoScroll属性设置为False。这将隐藏滚动条。我希望这为你指明了正确的方向
myPanel.AutoScroll = False
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。除了在表单上放置控件外,您还需要使用一些面板、填充、最小/最大大小和停靠 下面是您可以放置在空白新表单后面的示例代码1。在设计器或运行时调整窗体的大小,您将看到水平滚动条不会显示,字段也不会重叠。我还为字段指定了一个最大宽度,以便更好地测量:
