Bind TextBox Width from ColumnDefinition Width XAML WPF
提问by soufiane labdai
In my WPF project i want to bind TextBox Width property from ColumnDefinition Width. Now, it's not working !
在我的 WPF 项目中，我想从 ColumnDefinition Width 绑定 TextBox Width 属性。现在，它不起作用！
I used a converter (GridLengthConverter) to convert data to width.
我使用转换器 (GridLengthConverter) 将数据转换为宽度。
This is my code :
这是我的代码：
<TextBox Grid.Column="1" Grid.Row="1" Style="{StaticResource SearchWhite}" Name="tbSearch"
Visibility="{Binding RelativeSource={RelativeSource AncestorType={x:Type mic:DataGrid}},
Path=ShowSearchBoxes, Converter={StaticResource visibleConverter}}" Width="{Binding
RelativeSource={RelativeSource FindAncestor,AncestorType={x:Type ColumnDefinition}},
Path=Width, Converter={StaticResource gridLengthConverter}, Mode=TwoWay}"/>
gridLengthConverter is GridLengthConverter from assembly : PresentationFramework.
gridLengthConverter 是来自 assembly 的 GridLengthConverter：PresentationFramework。
I get an error "Unable to convert data attribut 'Converter'..." (translation from french).
我收到错误消息“无法转换数据属性 'Converter'...”（法语翻译）。

<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Name="col1" Width="200"/>
<ColumnDefinition />
</Grid.ColumnDefinitions>
<TextBox Width="{Binding ElementName=col1, Path=Width}"
Grid.Column="0" Height="20"/>
</Grid>

If you are binding your text box to width of column 1, all you need to do is leave out the Width property definition and set HorizontalAlignment = "Stretch"
如果您将文本框绑定到第 1 列的宽度，您需要做的就是省略 Width 属性定义并设置 HorizontalAlignment = "Stretch"
For example:
例如：
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="50" />
<ColumnDefinition Width="100" />
</Grid.ColumnDefinitions>
<TextBox Grid.Column = "1" HorizontalAlignment="Stretch" Height="120" Name="textBox1" />
</Grid>
The textbox now should be of height 120 and width 100.
文本框现在应该是高度 120 和宽度 100。
