Is it possible to add more characters after a binding in xaml?
提问by Terry
I was wondering something, and couldn't find any relevant topics. I have following binding :
我想知道一些事情，但找不到任何相关主题。我有以下绑定：
Content="{x:Static resx:Resource.Form_OtherOption_Description}"
This will place a string in a label. What i was asking myself is if i can add a ":" after that binding, not in code, just in xaml. The label represent something like "Name :". But adding the ":" as part of the binding is not an option.
这将在标签中放置一个字符串。我问自己是否可以在绑定之后添加一个“：”，而不是在代码中，而是在 xaml 中。标签表示类似“名称：”的内容。但是添加“:”作为绑定的一部分不是一个选项。

You could accomplish this with something like:
您可以使用以下方法完成此操作：
<TextBlock Text="{Binding Source={x:Static resx:Resource.Form_OtherOption_Description},
StringFormat={}{0}:}" />
Edit:<Label>s Contentproperty does not respect the StringFormatproperty of a binding apparently. Which I've found has been moved to the ContentStringFormatproperty on the <Label>.
编辑：<Label>sContent属性显然不尊重StringFormat绑定的属性。我已经发现已经移动到ContentStringFormat的财产<Label>。
<Label Content="{x:Static resx:Resource.Form_OtherOption_Description}"
ContentStringFormat="{}{0}:" />

If you're using WPF 4.0, you could also do this:
如果您使用的是 WPF 4.0，您也可以这样做：
<TextBlock>
<Run Text="{Binding SomeLabel}"/>
<Run Text=":"/>
</TextBlock>
This actually concatenates the two strings coming from two Runtag and copied into TextBlock.Textproperty!.
这实际上将来自两个Run标签的两个字符串连接起来并复制到TextBlock.Text属性中！
Using this approach you can even bind to different properties in presenter, and display it in a single TexBlock. See this excellent example:
使用这种方法，您甚至可以绑定到 Presenter 中的不同属性，并将其显示在单个TexBlock. 看看这个很好的例子：

You can also use MultiBinding with StringFormat e.g:
您还可以将 MultiBinding 与 StringFormat 一起使用，例如：
<TextBlock>
<TextBlock.Text>
<MultiBinding StringFormat="ID {0} Name: {1} Age: {2}">
<Binding Source="{x:Static resx:SomeResx.ID}"/>
<Binding Path="Name"/>
<Binding Path="Age"/>
</MultiBinding>
</TextBlock.Text>
</TextBlock>
You can use this in a content control TextBlock TextBlock.Text (sorry I couldn't get the code to show up for this above)
您可以在内容控件 TextBlock TextBlock.Text 中使用它（抱歉，我无法在上面显示代码）

Yes you can. Here I add "testing" after binding text(clouds.all) in windows phone.
是的你可以。这里我在windows手机中绑定文本（clouds.all）后添加“测试”。
<TextBlock Text="{Binding Path=clouds.all, StringFormat=\{0\}testing}"/>

Try Binding's property StringFormat- it can do very simply what you want.
尝试使用 Binding 的属性StringFormat- 它可以非常简单地完成您想要的操作。

if you use a label inside a progress bar you can use this way:
如果您在进度条内使用标签，您可以使用这种方式：
<Label x:Name="Progress" VerticalAlignment="Stretch" HorizontalAlignment="Stretch" HorizontalContentAlignment="Center" VerticalContentAlignment="Center" FontWeight="Bold" Foreground="White" Opacity=".7"
Content="{Binding Path=Value, RelativeSource={RelativeSource TemplatedParent}}" ContentStringFormat="{}{0}%">
in this way you can visualize the value of progressbar with a % added.
通过这种方式，您可以通过添加 % 来可视化进度条的值。

You can create a converter that takes the input string and adds the ":".
您可以创建一个转换器，它接受输入字符串并添加“:”。
public class AddStringToStringConverter : IValueConverter
{
#region IValueConverter Members
public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
{
string input = value as string;
string suffix = parameter as string;
return input + suffix;
}
public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
{
throw new NotImplementedException();
}
#endregion
}
Xaml:
Xml：
<Window.Resources>
<local:AddStringToStringConverter x:Key="AddStringToStringConverter"/>
</Window.Resources>
...
<Label Text="{Binding Source={x:Static resx:Resource.Form_OtherOption_Description}, Converter={StaticResource AddStringToStringConverter}, ConverterParameter=:}"/>
Or something like that. Tried it and it worked for my source at least.
或类似的东西。试过了，它至少对我的来源有用。
If you have whitespace and the like in you ConverterParameteryou can use signle quotes to make sure it does not get disposed.
如果您有空格等，您ConverterParameter可以使用单引号来确保它不会被处理。
Edit:Oh right... yeah... there's also StringFormatwhich i have never needed before, ehehehe...
编辑：哦，对了......是的......还有StringFormat我以前从未需要过的，呵呵......
