C#设置自动滚动位置 [英] c# setting autoscrollposition

问题描述

你好，
我有一个用户控件，它是可滚动控件，并且我想更改其自动滚动位置(仅X值).

我正在这样做:

Hello,
I have a user control, which is scrollable control, and I want to change its autoscrollposition (only the X value).

I''m doing it like this:

int newScrollX = myFunction();
Point p = new Point(newScrollX, this.AutoScrollPosition.Y);
this.AutoScrollPosition = p;

newScrollX获取正确的值，p获取正确的点，但是在AutoScrollPosition设置行之后，AutoScrollPosition为(0,0).

有什么问题吗?

谢谢

newScrollX gets the correct value, p gets the correct point, but after the line of AutoScrollPosition setting, the AutoScrollPosition is (0,0).

What is the problem?

Thanks

推荐答案

它可能是无效值.您需要检查您的控制客户端大小，而不是System.Windows.Forms.ScrollableControl.AutoScrollMinSize.另外，请确保您的System.Windows.Forms.ScrollableControl.AutoScroll是真实的，并且将System.Windows.Forms.ScrollableControl.AutoScrollMargin与System.Windows.Forms.ScrollableControl.AutoScrollOffset一起考虑在内.您可能根本不了解这个概念，就像过去某些成员一样.

It might be invalid value. You need to check up your control client size, versus System.Windows.Forms.ScrollableControl.AutoScrollMinSize. Also, make sure your System.Windows.Forms.ScrollableControl.AutoScroll is true and take into account System.Windows.Forms.ScrollableControl.AutoScrollMargin with System.Windows.Forms.ScrollableControl.AutoScrollOffset. It''s possible that you simply did not understand the concept, as happens with some members in the past.
