Changing culture at runtime

[Christie Admin]

Hi,

 

in our application we have the flexibility to change the culture at runtime and I would like to know if it's possible with Telerik?

 

Thank'

Hello,

Yes, it's possible to change the culture at runtime. You can set it programmatically.

Thread.CurrentThread.CurrentCulture = new CultureInfo("de");
Thread.CurrentThread.CurrentUICulture = new CultureInfo("de");

You can read more about this in our Localization article.

If you have any other questions, please don't hesitate to contact us again.

Hi Dinko,

 

this will change Telerik controls also (ie: RadScheduleView)???

 

Thank's

Hello Alain,

You can change the localization of RadScheduleView at runtime in a few steps. Firstly you can set the
DefaultCulture property of the LocalizationManager to the new culture. Then you need to reset the template of the RadScheduleView control in order for the changes to take effect. For example:

var cultureInfo = new CultureInfo("de-DE");
LocalizationManager.DefaultCulture = cultureInfo;
var myTemplate = this.MyScheduleView.Template;
this.MyScheduleView.Template = null;
this.MyScheduleView.Template = myTemplate;

I have created a sample project using the code snippet above to see how you can implement the scenario.
You can also check the Localization help article and demo.

Hope this will help.

Great Dinko :)

Thank's

Hi Alain,

You can change the localization of the Telerik controls at runtime in two ways. The first one is to set the static UseDynamicLocalization property of the LocalizationManager to true before calling the InitializeComponent() method of the application. This way when you change the localization manager's culture, the localized strings of the control will be updated. Keep in mind that this functionality is implemented only for part of our controls. For example, RadGridView and RadScheduleView won't work using this approach. The second one is to reset the template of the control as demonstrated in my previous answer. 

To get all Telerik controls in your application, you can subscribe for their Loaded event using EventManager.RegisterClassHandler() method and store them in a collection. Then you can iterate through the collection and reset the templates of all it's elements.

EventManager.RegisterClassHandler(typeof(Control), Control.LoadedEvent, new RoutedEventHandler(OnControlLoaded));

Or you can use the ChildrenOfTypeExtensions.ChildrenOfType<T>() method to get all Telerik controls when you change the culture.

Also, I have created a sample project with several Telerik controls where you can see how to implement these approaches.

I have (still) the same problem.

Your recent sample, Dinko, solved most problems.But, the view selection button (navigation bar) is still not updated after culture change.

I would like to continue use our current version (2016.2.613), but I've also tested recent version (2017.3.1018).

What I have to do, do get navigation but to be updated too.

Thanks
Lukas

Further, the internal dialogs (create new appointment, delete appointment confirmation) are always english, even the application starts with german culture.

Hello Lukas,

I wasn't able to reproduce the mentioned issues. The dialogs and the buttons language is changed properly. I also answered your ticket. Can you please get back there with more information on the matter.
