Question

我正在尝试在我的应用程序上应用整体格式。该应用程序已经构建。在数据网格中显示数据时，我想格式化并右对齐所有包含数量的文本块。这是可以使用某种触发器或任何其他方式吗？是否可以知道绑定路径是否包含单词“amount”以及是否应用了所需的格式。

基本上我想根据整个应用中的值从一个位置控制格式和对齐。因此，长期运行很容易改变。

以下是我的XAML视图：

您可以尝试绑定TextBlocks，如下所示：

<TextBlock Text="{Binding Path=TotalAmount}" TextAlignment="{Binding Path=TotalAmount, Converter="{StaticResource ContentToAlignmentConverter}" />

您必须自己实现ContentToAlignmentConverter。我不会在这里放一个代码，因为这取决于你想要检查它的内容，但它自己很容易做到。 Here is a sample of a value converter in WPF

修改

如果你想对DataGrid中的所有TextBlocks应用这些更改，你应该尝试这样的事情（不确定它是否会起作用，但应该如此）：

<DataGrid.Resources> <Style TargetType="{x:Type TextBlock}" BasedOn="{DynamicResource GridTextBlock}"> <Setter Property="TextAlignment" Value="{Binding RelativeSource={RelativeSource Mode=Self}, Path=Text, Converter="{StaticResource ContentToAlignmentConverter}}" /> </Style> </DataGrid.Resources>
