I have a new project. I drop a textbox control on it. I open up the properties window, and I can change the height and hit enter or click out of the box and it will update the designer, but when I try to change the height it resets back to the default value. Why is that? I had the same issue with a Label, but I turned off AutoSize and it allowed me to modify the values. Is there some property I can turn off to be able to modify the Height of a textbox in the design view? I'm using Visual Studio 2010 sp1. I had the same issue in Visual Studio 2008. I am new to Windows forms.
我有一个新项目。我删除了一个文本框控件。我打开属性窗口，我可以更改高度并点击输入或单击开箱即可更新设计器，但当我尝试更改高度时，它会重置为默认值。这是为什么？我对Label有同样的问题，但我关闭了AutoSize，它允许我修改值。是否有一些属性可以关闭，以便能够在设计视图中修改文本框的高度？我正在使用Visual Studio 2010 sp1。我在Visual Studio 2008中遇到了同样的问题。我是Windows窗体的新手。

You need to set TextBox.Multiline property as true .
您需要将TextBox.Multiline属性设置为true。
TextBox1.Multiline = true;

Checking Multiline will allow to resize but it also allows enter(return) key in the textbox.
The Height of a non-Multiline TextBox is fixed by the size of the Font.
Reduce to textbox Font size, the TextBox will resize automatically.
检查Multiline将允许调整大小，但它也允许在文本框中输入（返回）键。非多行TextBox的高度由Font的大小确定。减少到文本框字体大小，TextBox将自动调整大小。
