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)?

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)。
