How to TextWrap a TextBlock within a width Auto Column?
提问by King Chan
Consider something as follows:
考虑如下：
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="Auto"/>
</Grid.ColumnDefinitions>
<TextBlock x:Name="WrapTextBlock" Grid.Column="0" Text="123 456 789 0123 4456 123 123 123 123 1 23 123 " TextWrapping="Wrap" />
<TextBlock x:Name="NotWrapTextBlock" Grid.Column="1" Text="GGG" />
</Grid>
This XAML will allow WrapTextBlocktext to be wrap, doing this, WrapTextBlockwill take all the space and push NotWrapTextBlockto the right.
此 XAML 将允许WrapTextBlock文本换行，这样做WrapTextBlock将占用所有空间并NotWrapTextBlock向右推。
But what I want to do is to have WrapTextBlocktake as less space as possible, pushing NotWrapTextBlockright after WrapTextBlockand fill the right side with empty space.
但我想要做的是WrapTextBlock尽可能少地占用空间，紧随NotWrapTextBlock其后WrapTextBlock并用空白空间填充右侧。
Which means the following:
这意味着以下内容：
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<TextBlock x:Name="WrapTextBlock" Grid.Column="0" Text="123 456 789 0123 4456 123 123 123 123 1 23 123 " TextWrapping="Wrap" />
<TextBlock x:Name="NotWrapTextBlock" Grid.Column="1" Text="GGG" />
</Grid>
But the thing here is, now the text in WrapTextBlockwouldn't wrap anymore.
但这里的事情是，现在文本WrapTextBlock不会再换行了。
I mean something like follows:
我的意思是这样的：
When text is too long it requires to warp:
当文本太长时，它需要扭曲：
When text is short enough that doesn't requires to warp:
当文本足够短不需要变形时：

The reason is by defining your ColumnDefinitionas Auto or * you have nothing to limit the size available for your TextBlockto consume. So it would be expected behavior for the Text to not Wrap. So you'll have to define a Widthor MaxWidthon either the ColumnDefinitionor the TextBlockdirectly. So for instance;
原因是通过将您定义ColumnDefinition为 Auto 或 * 您没有任何限制可供您TextBlock使用的大小。因此，文本不换行是预期的行为。因此，您必须直接在 the或 the上定义 aWidth或。例如；MaxWidthColumnDefinitionTextBlock
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" MaxWidth="50"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<TextBlock x:Name="WrapTextBlock" Text="123 456 789 0123 4456 123 123 123 123 1 23 123 " TextWrapping="Wrap" />
<TextBlock x:Name="NotWrapTextBlock" Grid.Column="1" Text="GGG" />
</Grid>
Will give you your wrap, if you want to say instead only allow it to take for example say, 7% of the space the grid has to use, change the Widthto something like;
会给你你的包裹，如果你想说只允许它以例如说，网格必须使用的空间的7％，改变Width为类似的东西；
<Grid.ColumnDefinitions>
<ColumnDefinition Width="0.07*"/>
<ColumnDefinition Width="0.93*"/>
</Grid.ColumnDefinitions>
So the first column will take up 7% of the space available, and the right column will consume the rest. Hope this helps.
因此，第一列将占用可用空间的 7%，而右列将占用其余空间。希望这可以帮助。
Edit Addition:
编辑补充：
What you're showing pretty much aligns with your first snippet wherein the first column should push, the second one should only allow enough space for its content to show;
您所展示的内容与您的第一个片段几乎一致，其中第一列应该推送，第二列应该只允许足够的空间来显示其内容；
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="Auto"/>
</Grid.ColumnDefinitions>
<TextBlock x:Name="WrapTextBlock" Grid.Column="0" Text="123 456 789 0123 4456 123 123 123 123 1 23 123 " TextWrapping="Wrap" />
<TextBlock x:Name="NotWrapTextBlock" Grid.Column="1" Text="GGG" />
</Grid>
