Some strings in Dialogs from .wxl are not replaced in Custom WPF UI

[kipamgs]

Nuget: WixSharp-wix4.WPF Version 2.3.1 (Also happens in earlier versions) Project was created with the WixSharp Managed Setup - Custom WPF UI (WiX4)template.

As you can see in the image below not all strings are replaced with their value. The only of my custom values that is replaced is the lower left "Test Connection" button but all of them are defined in the same wxl file.

For now I can do a workaround and add DatabaseURLHint.Text = _session?.Format(Host?.MsiRuntime().UIText["UIDatabaseURLHint"]); for all strings to the Init function of the dialog but it would be nice to find the cause of this problem.

I'm merging the wxl file with the existing english one with runtime.UIText.InitFromWxl(e.Session.ReadBinary(lang_file), true);.

Will have a look at this on the weekend.

I'm merging the wxl file

Yes this is the correct technique. Is it possible that you are not doing it at right time that is UIInitialized project event:

https://github.com/oleg-shilo/wixsharp/blob/6be8a97236b57ea00dcfa18276560a1111da3276/Source/src/WixSharp.Samples/Wix%23%20Samples/Managed%20Setup/MultiLanguageUI/setup.cs#L82-L98

You can find the relevant samples in the samples library:

• CustomUIDialog.WPF
• CustomUI.Dialog
• MultiLanguageUI

I initialized it exactly as in the example. I created a small example project with the problem. Example.zip

Great, I will have a look on weekend.

OK, there are a few problems here. It's kinda a perfect localization storm :)

Please note I am reviewing your example that you shared.

1. Small problem with your code You probably noticed that your TestConnecttionButton is localized. But your TextBlocks are not. This is because WixzSharp localization is translating ContentControl.Content (e.g. in buttons) and TextBlock.Text text. Though in your case did not set TextBlock.Text property but a TextBlock.Content property`

   <TextBlock TextWrapping="Wrap"><Run Text="[UI_DB_URL_HINT]" /></TextBlock>

   Thus WixSharp is translating the empty property Text. To solve this problem you either need to set text manually or simply roll it back to TextBlock.Text approach.

   <TextBlock TextWrapping="Wrap" Text="[UI_DB_URL_HINT]"></TextBlock>

2. Bigger problem with auto localization in WixSharp () It is a WixSharp limitation that is simply triggered by you placing your StackPanel in the ScrollViewer. The problem is that WixSharp translates the content of the WPF dialog (e.g. SQLConnectionDialog) when its parent Loaded event is called. It works fine in all cases except when the visual tree generation is somehow delayed (e.g. because of the ScrollViewers). I just have fixed this problem by executing the dialog localization from the actual dialog Loaded event (not from its parent). It works now fine and the fix will be available in the very next release. In the meantime you can solve this problem by calling localization manually from the dialog onload event:

   public SQLConnectionDialog()
   {
      InitializeComponent();
      this.Loaded += (s, e) => this.Localize();
   }

There are quite a few moving parts here, but basically, you will need to get rid of <Run and call Localize from the onLoad handler (or get rid of the ScrollViewer. But when the next release is out, the only constraint will be the use of <Run...

===========================

I have also added this information to the Localization wiki.

Thanks for the quick reply.

   ```
   <TextBlock TextWrapping="Wrap"><Run Text="[UI_DB_URL_HINT]" /></TextBlock>
   ```

I overlooked that one.

   ```

I couldn't ask for more than a 1 line solution :)
