How to set XAML Width in percentage?
提问by Tom
I am trying to create a button in XAML with a 80% width, but I can't seem to figure out how. It's apparently not as easy as using Width="80%". I have been thinking this can be done by detecting the screen width somehow and multiply that by 0.8 and use that as the width, but I am not sure how I can do this in XAML. Perhaps this has to be done in the .cs file and then adjust the width from there. Does anyone have a solution for this?
我正在尝试在 XAML 中创建一个宽度为 80% 的按钮，但我似乎无法弄清楚如何。这显然不像使用 Width="80%" 那样容易。我一直认为这可以通过以某种方式检测屏幕宽度并将其乘以 0.8 并将其用作宽度来完成，但我不确定如何在 XAML 中执行此操作。也许这必须在 .cs 文件中完成，然后从那里调整宽度。有没有人对此有解决方案？

Is it WPF?
是WPF吗？
If yes, then wrap your control (button) in grid. Then specify the grid column definition. Example:
如果是，则将您的控件（按钮）包裹在网格中。然后指定网格列定义。例子：
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="0.2*"></ColumnDefinition>
<ColumnDefinition Width="0.8*"></ColumnDefinition>
</Grid.ColumnDefinitions>
<Button Grid.Column="1" Grid.Row="0"></Button>
</Grid>
Edit:Forget to close <Button>tag.
编辑：忘记关闭<Button>标签。

I think the more proper way would be
我认为更合适的方法是
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="2*"></ColumnDefinition>
<ColumnDefinition Width="10*"></ColumnDefinition>
</Grid.ColumnDefinitions>
<Button Grid.Column="1" Grid.Row="0"></Button>
</Grid>
