Как связать wpf ComboBox, чтобы изменить язык без записи в xaml.cs?

Question

У меня есть комбинированный список wpf, как показано ниже.

<ComboBox  Margin="71.421,3.417,-0.002,2.998" Width="167.244" Height="20" ToolTip="Change language settings" Padding="4,1,4,0" VerticalContentAlignment="Center" >
                    <ComboBoxItem Content="English" IsSelected="True"   />
                    <ComboBoxItem Content="中文" />
</ComboBox>

И у меня есть этот класс культуры ниже.

public class SpecificCultures

    }

В ViewModel.cs,

, еслиизменился выбор в выпадающем списке,

Мне нужно вызвать функцию, чтобы сохранить культуру, выбранную пользователем.

Например.

 SaveCuluterID(string culutredID)
{
   // process here to change language of the application, this is already done and working. 
}

, если пользователь выбирает английский язык, culturedID должен быть SpecificCultures.EN_US.Если это китайский, должен быть SpecificCultures.ZH_CN.Это работает, если я пишу в xaml.cs.Но мне нужно сделать эту логику в ViewModel.cs, так как наш рабочий процесс должен быть связан с привязкой. Независимо от того, что выберет пользователь, мне нужно изменить его на CultureID.Спасибо.

Answer 1

Я бы предложил установить для каждого свойства ComboBoxItem «Tag» нужную вам культуру или строку, а затем задать для SelectedValuePath значение «Tag», чтобы оно связывалось с нужным свойством.

Вот хороший пример / объяснение: http://johnpapa.net/binding-to-silverlight-combobox-and-using-selectedvalue-selectedvaluepath-and-displaymemberpath

Answer 2

Вы можете привязать выбранный элемент к свойству, объявленному в viewmodel

SelectedItem={Binding SelectedCulture}
