Issue regarding Localization for RadEditor Table

[Atul]

Hi, I am using Telerik RadEditor, and some of the localization text is missing for the table style builder window. I have followed this post, and some localizations are still missing. Can you share the latest localization files for the en-US culture here?

I have attached the screenshot of the issue.

Hi Atul,

Please find attached the latest version of the RadEditor localization RESX files.

Keep in mind that the issue might also be caused by JavaScript errors or blocked resources. I recommend checking your browser's developer tools: look at the console for any JS errors and the Network tab for blocked files.

Also, you might want to test the RadEditor Localization live demo to see if the issue happens there too:

Hope this helps!

Hi Rumen,

I can see the following error while opening the table style builder window. Can you help me with this?

It is working perfectly fine here https://demos.telerik.com/aspnet-ajax/editor/examples/localization/defaultcs.aspx

[Rumen]

The screenshot indicates there are 4 errors, but only one is visible due to the top part being cut off—a 404 error for a missing PNG file, which appears unrelated to the main issue. Could you please share a full screenshot that displays the remaining errors?

The violation warnings shown in the console are related to the use of document.write(), which is deprecated but not likely to be the root cause of the problem either.

Also, could you check the Network tab to see if there are any blocked or failed resources?

[Atul]

Hi Rumen,

Network tab looks fine. The issue was resolved when I replaced my localization files with yours. Thank you for being so helpful.

Thank and Regards,
Atul

[Rumen]

Great! Thank you for sharing the good news. I am glad that everything is fine now!

Hi Rumen,

Can you provide the latest localization files for he-IL?
I am getting the same error for culture he-IL.

[Rumen]

Thank you for your inquiry Atul,

We currently only support and maintain localization files for en-US, de-DE, and fr-FR. Any other localization files, including he-IL, are provided by customers and may be outdated, as appears to be the case here.

However, if you decide to create a new he-IL localization for RadEditor based on the latest en-US version and share it with us, we would greatly appreciate your contribution. As a token of our appreciation, we will reward your effort with 3000 points.

Hi Rumen,

Can you please help me with one more issue?

For RTL languages, the "Back" and "Next" buttons on the Image Manager screen appear inverted.

How should I fix it? I also checked here, also the direction of the arrows is wrong for RTL languages.

Please help us fix this issue.

[Rumen]

Hi Atul,

Can you confirm the following: while the Back and Forward buttons are positioned correctly, the arrow icons themselves are still pointing in the LTR direction. Is that the problem you are reporting?

If yes, to change the icons of both buttons in the dialog, you should:

• Create your own RadEditor_Dialogs_RTL.CSS file that you will load in the dialog with this contents:
  
  

  .icnForward:before {
      content: "\e100" !important;
  }
  
  
  .icnBack:before {
      content: "\e101" !important;
  }
  

  
  
• Load the CSS file in RadEditor dialog through the DialogsCssFile="~/RadEditor_Dialogs_RTL.css" property. Here the path points to the RadEditor_Dialogs_RTL.css placed in the root of the web application.

Hi Rumen, 

Can you please provide the latest CSS style files used for RTL?

I am facing the following error:- 

[Rumen]

I was unable to reproduce the issue in the RTL demo, but I suspect it may be caused by long localization strings. You can try the following:

• Shorten the localization strings
• Use Chrome or Firefox developer tools to inspect the rendered HTML and styles, which may help you identify and resolve the issue.

Hi Rumen,

Whenever I click on any image and then click on the image editor the image does not loads up in the image editor.

[Rumen]

It will be hard to help you without providing a repro project, but here are some troubleshooting tips:

• Look for errors in the console
• Make sure that the Telerik assemblies and any external dialog files (if used) are up to date and obtained from the same installation.

[Atul]

Where can I check the 2nd point?

 

[Rumen]

You can find which is that version as explained here: https://docs.telerik.com/devtools/aspnet-ajax/knowledge-base/common-assembly-version. If there are external dialogs folder, it should be obtained from the same installation as the assemblies version.

Hi Rumen,

Some clarification. It was working earlier. I just added the latest localization files, and from that point, the image editor preview is not working. I have shared the screen recording with the Console error for you to take a look:- https://jam.dev/c/18f43c4f-cbd9-4733-99ae-2fc3aa206759

Help me fix the issue 🙏

Hi Atul,

Thanks for the update and for sharing the screen recording.

From what you've described, and considering that replacing your localization files with the English ones resolved the issue, it's very likely that the problem lies within one or more of the localization RESX files you have customized/translated and your app is using.

Keep in mind that RadEditor and its dialogs depend on a large number of localized strings, and diagnosing issues like this can be quite challenging. Even a single malformed entry or unsupported character can break functionality, especially if it doesn't comply with the .resx schema. Since this involves custom localization outside the officially supported cultures, it's beyond the scope of what we can fully support.

Here’s what we recommend for troubleshooting:

1. Start clean – Take the latest working English localization files and rename them for your specific culture (e.g. he-IL). Verify that the dialog works as expected.
2. Gradually reapply your translations – One by one, replace the English files with your localized versions, testing after each replacement to see if the issue returns.
3. Narrow it down – Once the problem resurfaces, you'll know which file is causing it. From there, comment out or remove strings in sections until you pinpoint the exact line that breaks the image editor preview.
4. Watch out for special characters – Certain symbols or formatting might not be supported in .resx files, especially in XML attributes or CDATA sections. Make sure all characters are properly escaped.

This step-by-step process should help isolate the problematic string and allow you to correct it without compromising the rest of your localization work.

Hi Rumen,

Thank you for your reply. I am getting this preview issue in the en-US culture. I have used the localization files provided by you above. I have not made any changes to the localization file provided by you. But from the point of replacing the localization files with the ones you shared I am getting this issue.

[Rumen]

The app-globalresources.zip files I provided may not be compatible with the version of Telerik.Web.UI.dll used in your application. It’s best to create a new project and add the global resource files from the same Telerik installation that matches the Telerik.Web.UI.dll version you're using. Then, verify whether the dialog works as expected.

Since this forum thread has grown lengthy and shifted focus, I recommend opening a support ticket. Please include a simple, runnable project that reproduces the issue – this will help us assist you more efficiently.

Hi Rumen,

I was referring to the direction of the arrows, which is wrong. They are pointing to each other. They should be pointing in the opposite direction instead.

[Rumen]

Thank you for the confirmation! I can confirm that the provided solution in my earlier reply changes the direction of both icons to:
