Changing input language

[olegsavelos]

I am trying to implement an input language change for an application using WebView2 hosted in WPF application, the problem is that most of the common ways to change the language don't work.

WPF InputLanguageManager.Current.CurrentInputLanguage no effect
Win32 ActivateKeyboardLayout no effect

Changing the windows language manually does make WebView to use correct language, so the question is whether I am missing something or the only way is to programmatically switch windows input language ?

I have outlined the problem here

@olegsavelos , can you try CoreWebView2EnvironmentOptions.Language Property to see whether it helps with your scenario ?

I have tried specifying the language in OnWebViewInitializing event handler

_BLAZOR_WEB_VIEW.BlazorWebViewInitializing = new EventHandler<BlazorWebViewInitializingEventArgs>(OnWebViewInitializing);

private void OnWebViewInitializing(object sender, BlazorWebViewInitializingEventArgs e)
 {
  e.EnvironmentOptions = new CoreWebView2EnvironmentOptions()
  {
      Language = "gr",
  };
 }

Nothing changes, all inputs are in English.
