如何防止容器自动滚动当部分可见的子控件获得焦点？ [英] How to prevent container to autoscroll when a partially-visible child control got focus?

问题描述

具有启用滚动条的面板有许多按钮。如果我按下列表键，焦点在按钮之间导航。

当部分可视按钮有焦点时，面板会自动滚动以完全显示按钮。 >

有没有办法阻止滚动？

解决方案

创建自己的Panel控件并覆盖 ScrollToControl 方法：

 公共类PanelEx 
继承Panel 
 
受保护的覆盖函数ScrollToControl（activeControl As Control）As 
返回Me.AutoScrollPosition 
 End Function 
 
 End Class 
  

A panel with enabled scrollbars has many buttons. If I push the tabulation key, focus navigates between buttons.

When a partially visible button has focus, the panel scrolls itself in order to completely show the button.

Is there a way to prevent that scrolling?

解决方案

You would have to create your own Panel control and override the ScrollToControl method:

Public Class PanelEx
  Inherits Panel

  Protected Overrides Function ScrollToControl(activeControl As Control) As Point
    Return Me.AutoScrollPosition
  End Function

End Class
