why the culture is not getting set in my application with Thread.Current code?

Question

I have created a localization application in WPF. I have bind the controls in the xaml like this.

<Label Name="languageLabel" Content="{x:Static Resources:Resources.languageLabel}" Style="{StaticResource CommonRepSecStyle}" />

Everything works fine but still I am not sure the techniques I applied are good. I created a resource manager and assigned the string values to controls like this.

        Dim culture As CultureInfo = CultureInfo.CreateSpecificCulture(cultureName)
        Dim localResource As System.Resources.ResourceManager = New System.Resources.ResourceManager("LocalTest.Resources", System.Reflection.Assembly.GetExecutingAssembly())

        languageLabel.Content = localResource.GetString("languageLabel", culture)
       stateLabel.Content = localResource.GetString("stateLabel", culture)
        cityLabel.Content = localResource.GetString("cityLabel", culture)
       stateComboBox.Text = localResource.GetString("stateComboBox", culture)
        cityComboBox.Text = localResource.GetString("cityComboBox", culture)
        infoLabel.Content = localResource.GetString("infoLabel", culture)
        infoTextBox.Text = localResource.GetString("infoTextBox", culture)
        localResources.ReleaseAllResources()

It does not seems to work until I assigned the values to the controls? Is there any way to improve this? Thank you!

    Private Sub SetControlsCulture()
        Select Case cultureName
            Case "fr-CA"
                UIControlsBinding()

   Private Sub UIControlsBinding()
        Dim culture As CultureInfo = CultureInfo.CreateSpecificCulture(cultureName)
        Dim localResource As System.Resources.ResourceManager = New      System.Resources.ResourceManager("LocalTest.Resources", System.Reflection.Assembly.GetExecutingAssembly())
     languageLabel.Content = localResource.GetString("languageLabel", culture)
     stateLabel.Content = localResource.GetString("stateLabel", culture)
     cityLabel.Content = localResource.GetString("cityLabel", culture)
     stateComboBox.Text = localResource.GetString("stateComboBox", culture)
     cityComboBox.Text = localResource.GetString("cityComboBox", culture)
    infoLabel.Content = localResource.GetString("infoLabel", culture)
    infoTextBox.Text = localResource.GetString("infoTextBox", culture)
    localResources.ReleaseAllResources() 
    End Sub
    End class
    End Namespace

I did it in the xaml. But it does not change the culture until I implement it in the code behind. — user1521601, Mar 04 '13 at 20:22
Check this idea: http://stackoverflow.com/questions/10039102/is-there-any-way-to-use-staticresource-in-a-wpf-control-library-and-be-able-to-v In a nutshell: define your own class type, add custom properties on it, make these custom properties dependent on current culture and bind to them. This way your code doesn't have to know resource keys — Sten Petrov, Mar 04 '13 at 20:28

To add resources in WPF add a Resource.resx and a Resource.NL-nl.resx (or language of choice) file to the properties folder of you project. Add a resource with name StateLabel and a value in each resourcefile. Don't forget to change the Access Modifier to Public

Add xml namespace to your window/usercontrol: xmlns:Resources="clr-namespace:WpfApplication2.Properties" (where WpfApplication2 is your application name)

Add a label to your window/usercontrol <Label Content="{x:Static Resources:Resources.StateLabel}"></Label>

To change language call this from code to set the appropriate language (in this case Dutch):

System.Threading.Thread.CurrentThread.CurrentUICulture = new CultureInfo("nl-NL");

I have done this already. It is in vb.net and I have create a new folder Resources which has the language resource file. – user1521601 Mar 04 '13 at 21:27
and have tried the way you told me, but it did not work for me. – user1521601 Mar 04 '13 at 21:40
Ok. But it doesn't work? Why do you need to set the labels from code? What's the problem? – Ralf de Kleine Mar 04 '13 at 21:42
I did. It does not show any error in it when i build the application. – user1521601 Mar 04 '13 at 21:47
In your code you don't change the ui culture in the current thread. – Ralf de Kleine Mar 05 '13 at 01:00
Thank you for your time Ralf. I have included the complete code. – user1521601 Mar 05 '13 at 15:24
