我无法找到解决此问题的方法:
我正在使用ItemControls创建自己的表。要调整列的大小,我想将一个单元格的Width属性绑定到列的相应ActualWidth属性。
我尝试了以下操作,但它无效:
<StackPanel Orientation="Vertical">
<Border BorderBrush="Black" BorderThickness="1">
<ItemsControl ItemsSource="{Binding Data.Columns}" Margin="26,1,1,1">
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<StackPanel Orientation="Horizontal"/>
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
<ItemsControl.ItemTemplate>
<DataTemplate>
<!-- here i set the name of the column (Code) -->
<Border BorderBrush="Black" BorderThickness="1,0,0,0" Width="100" x:Name="{Binding Code}">
<TextBlock Text="{Binding Header}" />
</Border>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</Border>
<ItemsControl ItemsSource="{Binding Data.Rows}">
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<StackPanel Orientation="Vertical" />
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
<ItemsControl.ItemTemplate>
<DataTemplate>
<Border BorderBrush="Black" BorderThickness="1,0,1,1">
<StackPanel Orientation="Horizontal" Margin="1">
<Grid Width="25">
<General:SeverityIconControl Severity="{Binding Severity}" />
</Grid>
<ItemsControl ItemsSource="{Binding Values}">
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<StackPanel Orientation="Horizontal"/>
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
<ItemsControl.ItemTemplate>
<DataTemplate>
<!-- and here i'd like to bind to the ActualWidth of the corresponding column (Code)
but it is not working because ElementName={Binding LocalCode} does not work -->
<Border BorderBrush="Black" BorderThickness="1,0,0,0" Width="{Binding ActualWidth, ElementName={Binding LocalCode}}">
<TextBlock Text="{Binding Value}" />
</Border>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</StackPanel>
</Border>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</StackPanel>
有没有办法在不更改数据源的情况下解决这个问题(遗憾的是数据源无法编辑)?
答案 0 :(得分:1)
您无法绑定x:Name
(更多信息here),因为只有在构造函数中调用InitializeComponent()
时才会读取它。
最简单的方法是向DesiredWidth
对象添加Data
列,并将两个宽度绑定到该值(默认值为100)。
