WPF本地化扩展MVVM绑定 [英] WPF Localized Extension MVVM Binding

问题描述

我试图绑定在ViewModel中声明的名为["SampleName"]的属性.这里的SampleName是关键.但是，当尝试下面的代码时，它显示为空.

I am trying to bind a property called ["SampleName"] that is declared in ViewModel. Here SampleName is key. However, when trying below code, it display's empty.

<TextBlock FontSize="14" Text="{lex:BLoc Value=SampleName}" lex:ResxLocalizationProvider.DefaultAssembly="SAS.Resources" lex:ResxLocalizationProvider.DefaultDictionary="Report" HorizontalAlignment="Center" VerticalAlignment="Top" TextDecorations="Underline" FontWeight="DemiBold" Grid.Row="0" Grid.ColumnSpan="{Binding Path=SpanCount}" Grid.Column="0"/>

请建议我.

推荐答案

我使用的是正确答案，但这并不是100％稳定且线程安全的.现在我改用这种解决方案.

I was using the sugested answer, but that's not 100% stable and thread safe. Now I am using this solution instead.

我的观点:

xmlns:lex="http://wpflocalizeextension.codeplex.com"

<TextBlock Text="{Binding ElementName=LocProxy, Path=Result}"/>
<lex:LocProxy Name="LocProxy"
           Source="{Binding NameOfResourceKey}"/>

MyViewModel:

MyViewModel:

public string NameOfResourceKey { get; set; }

，然后将其设置为int ViewModel:

and then set it like this int ViewModel:

// Use your way to access classis Resources.resx file
NameOfResourceKey = nameof(Properties.Resources.YourLocalizedMessageKey);
// Use your function to RaiseProperty     
RaisePropertyChanged(nameof(NameOfResourceKey)); 

因此，您需要通过nameof引用资源文件中的Resource，将其设置为lex:LocProxy的源，然后在需要本地化字符串的任何位置绑定到LoxProxy Result.非常简单，然后将所有本地化都交给GUI，这是最佳的.

So you need to reference your Resource in resource file by nameof, set it as a source of lex:LocProxy and then Bind to LoxProxy Result, wherever you need your localized string. Quite simple, and then GUI is handlig all the localization, which is optimal.

要提高属性，可以使用bruno.almeida(OnPropertyChanged)中的函数，也可以使用MVVMLight nuget包示例，并像我一样在ViewModel中继承ViewModelBase.

And for Raise the property, you can use the function from bruno.almeida (OnPropertyChanged), or use for Example MVVMLight nuget package and inherit ViewModelBase in your ViewModel as I do.
