如何知道滚动条是否达到最大值 [英] How to know if the Scroll is up to maximum value

问题描述

我在主窗体中创建一个SplitContainer，并为其编写代码，如下所示.当然，我还实现了SplitContainer内部的一些控件，可以轻松移动它们.

I create a SplitContainer in my Main Form, and write code for it as below. Of course, I also have implemeted some controls inside the SplitContainer, and they can be moved without problem.

SplitContainer TheSC = new SplitContainer();
TheSC.Panel1.AutoScroll = true;
TheSC.Panel1.Scroll += new ScrollEventHandler(Panel1_Scroll);
        
void Panel1_Scroll(object sender, ScrollEventArgs e)
{
  Panel ThePanel = (Panel)sender;
  int CheckValue1 = e.NewValue;
  int CheckValue2 = e.OldValue;
  Type TheType = e.GetType();
  if (e.ScrollOrientation == ScrollOrientation.HorizontalScroll) { }

}

我的问题是:

当我将控件移到TheSC的边缘时，将显示滚动条，然后显示
绘制TheSC.Panel1的滚动条时，应该调用Panel1_Scroll事件，该事件如何得知滚动条是否已达到最大值? (当滚动条达到最大值时，我会设置一些标志.)

My question is :

When I move control to edge of TheSC, the scrollbar will be displayed, and then I
draw the scrollbar of TheSC.Panel1, the Panel1_Scroll event should be invoked, in the event, how can I know if the scrollbar has been up to maximum value ? (I would set some flag when the scrollbar is up to maximum value.)

推荐答案

这应该有帮助
