PictureBox不会更改其大小 [英] PictureBox does not change its size

问题描述

我在Form中有一个PictureBox和Button. PictureBox填充Form，并且SizeMode属性设置为StretchImage.

I have a PictureBox and a Button inside a Form. The PictureBox fill the Form and the SizeMode property is set to StretchImage.

当我单击按钮时，我想更改图像尺寸(更大)，并且我还希望显示滚动条.

When i click the button I want to change the image size (bigger), and I want also that the scrollbars appear.

因此，我在点击事件上更改了PictureBox的Size属性:

So, I change the Size property of my PictureBox on the click event:

pictureBox1.Size = new Size(800, 800);

但此代码无效.
为什么?

but this code does not have any effect.
Why?

我还尝试过使用GDI命令重绘图像本身，但是这种方式不会显示滚动条.

I also tried to redraw the image itself (using GDI commands), but in this way the scrollbars do not appear.

我怎么解决这个问题? 谢谢.

How can I solve this problem? Thanks.

推荐答案

设置:

pictureBox1.Bounds = this.ClientRectangle;
pictureBox1.Dock = DockStyle.None;

(对于PictureBox)，您将能够调整PictureBox本身的大小.

for your PictureBox and you will be able to resize the PictureBox itself.
