How do I get a TextBox to fill a resizable column?
提问by imekon
I'm trying to get a TextBox to fill the available space in a resizable column. The TextBox is part of a user control:
我正在尝试使用 TextBox 来填充可调整大小的列中的可用空间。TextBox 是用户控件的一部分：
<UserControl x:Class="TextBoxLayout.FieldControl"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<Label Grid.Column="0">Name</Label>
<TextBox Grid.Column="1"/>
</Grid>
</UserControl>
This user control is in a window with a vertical splitter:
此用户控件位于带有垂直分隔符的窗口中：
<Window x:Class="TextBoxLayout.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:TextBoxLayout"
Title="Text box layout" Height="400" Width="600">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition MinWidth="100"/>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition MinWidth="100"/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition/>
</Grid.RowDefinitions>
<local:FieldControl Grid.Column="0" Grid.Row="0" MaxWidth="200" HorizontalAlignment="Left"/>
<TextBlock Grid.Column="0" Grid.Row="1" Text="Testing"/>
<GridSplitter Grid.Column="1" Grid.Row="0" Grid.RowSpan="2" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Width="3"/>
<TextBlock Grid.Column="2" Grid.Row="0" Grid.RowSpan="2" Text="Testing"/>
</Grid>
</Window>
The problem is the TexTBox appears to be very narrow - what I'd want it to do is fill the left column and resize with the splitter. How do I do that?
问题是 TexTBox 看起来很窄 - 我希望它做的是填充左列并使用拆分器调整大小。我怎么做？

Use HorizontalAlignment="Stretch" instead of "Left" for FieldControl. Remove MaxWidth if required. Use TextAlignment to align text.
对 FieldControl 使用 HorizontalAlignment="Stretch" 而不是 "Left"。如果需要，删除 MaxWidth。使用 TextAlignment 对齐文本。

Just wanted to add to more examples for future code searches.
只是想为将来的代码搜索添加更多示例。
I put this in the top of the xaml file:
我把它放在 xaml 文件的顶部：
<UserControl.Resources>
<Style TargetType="{x:Type TextBlock}" x:Key="CenterCell">
<Setter Property="Background" Value="{Binding Included, Converter={StaticResource BoolToColorConverter}}"/>
<Setter Property="HorizontalAlignment" Value="Stretch"/>
<Setter Property="TextAlignment" Value="Center"/>
</Style>
</UserControl.Resources>
And then in the datagrid:
然后在数据网格中：
<DataGridTextColumn Header="Excluded" Binding="{Binding Excluded}" ElementStyle="{StaticResource CenterCell}"/>
This centers the text and sorting is still enabled. The textbox fills the cell and in this case is colored using a bool converter.
这使文本居中并且仍然启用排序。文本框填充单元格，在这种情况下使用布尔转换器着色。
