WPF DataGrid无法重现WindowsForms DataGrid的大小调整行为

Question

I'm looking over the web to reproduce a behaviour that I used almost every time in windows forms:

Columns resize to allow content to fit, if there isn't enough space a scrollbar appear. If I, for example, maximize the window which will allow me to have more space than what is required, the columns resize to fill all that space.

How to achieve this? Is this possible?

Answer 1

Use star Width

 <ColumnDefinition Width="1*"/>
 <ColumnDefinition Width="1*"/>

You can set the priority with the number.

 <ColumnDefinition Width="3*"/>
 <ColumnDefinition Width="1*"/>

the first column is 3 times the second one.

Answer 2

如果不通过代码，这是不可能的，我以数千种方式对其进行了测试，而且如果不通过C＃代码，就找不到解决方案。
