[英]WPF: StringFormat problems with a Label
These versions work as expected: 这些版本按预期工作:
<DataGridTextColumn Header="Total Units" Binding="{Binding TotalUnits, Mode=OneWay, StringFormat=N0}"/>
<TextBlock Text="{Binding TotalUnits, Mode=OneWay, StringFormat=N0}"/>
When I try it with a label, the StringFormat is iqnored and I get "123.000000" instead of "123". 当我用标签尝试它时,StringFormat是iqnored,我得到“123.000000”而不是“123”。
<Label Content="{Binding TotalUnits, Mode=OneWay, StringFormat=N0}"/>
TotalUnits is a Decimal. TotalUnits是十进制。
So, what's going on? 发生什么了?
Anything with a Content
property has a special ContentStringFormat
property you have to use rather than specifying the StringFormat in the Binding. 任何具有
Content
属性的东西都必须使用特殊的ContentStringFormat
属性,而不是在Binding中指定StringFormat。
Like this: 像这样:
<Window.Resources xmlns:sys="clr-namespace:System;assembly=mscorlib">
<sys:Int16 x:Key="MyValue">100</sys:Int16>
</Window.Resources>
<StackPanel DataContext="{StaticResource MyValue}">
<!-- using Label -->
<Label Content="{Binding}" ContentStringFormat="{}{0:C}" />
<!-- using TextBlock-->
<TextBlock Text="{Binding, StringFormat={0:C}}" />
</StackPanel>
