我無法找到解決此問題的方法:使用綁定元素名稱
我正在使用ItemControls創建自己的表。要調整列的大小,我想將一個單元格的Width-property綁定到列的相應ActualWidth-property。
我嘗試以下,但它不工作:
<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>
有沒有辦法解決這個不改變數據源(不幸的是,數據源不能編輯)的方法嗎?
如果你從代碼中設置了某些東西,你也許可以更新代碼中的綁定? – Vlad
