Questions on UI for ASP.NET AJAX Forum

I'm using a Telerik RadGrid with nested grids (using NestedViewTemplate) inside an ASP.NET Web Forms page. I've enabled scrolling with AllowScroll="true" and UseStaticHeaders="true", and set a fixed width for the outer container with horizontal scrolling.

The issue is that when I scroll horizontally to the right and then expand a nested row, the inner RadGrid (in the nested view) does not align properly or its scroll resets to the left. I want both the parent and child grids to stay aligned and scroll consistently, especially when expanding/collapsing rows.

Has anyone faced a similar issue or found a good way to synchronize scrolling between parent and nested grids?

Telerik UI for ASP.NET AJAX 2025 Q1 License Key Build Error

I have web projects that I am trying to update with the new 2025 Q1 assemblies and am getting a build error of the TelerikLicense.vb file.

I followed these instructions:

Search for AJAX.
Click on View key next to the Progress® Telerik® UI for ASP.NET AJAX.
Copy the Script Key.
Add a file to your project, e.g. TelerikLicense.cs (for VB projects add TelerikLicense.vb).
- In case of ASP Web Site solution, add the file to the App_Code folder.
Paste the Script Key into the file.
Build the project.

TelerikLicense.vb error BC30034: Bracketed identifier is missing closing ']'.

Any suggestions?

Filter not working on radGrid

I have created an application within Visual Studio 2019 and using c#.

The project has a page which uses a telerik RadGrid. It is populated on page load and I have filtering enabled on 3 of the columns. I have set the aspx for the columns to have AutoPostBackOnFilter="true" AllowFiltering="true" ShowFilterIcon="true"

The runs perfectly when ran in development environment but when I publish my application to the web server the filter does not work at all. Nothing happens if I tab out of the filter text box or if I select anything from the filter icon.

Can anyone advise what the issue could be please? I am using Telerik.web.ui version 2024.1.131.45

Thanks

Licensing Question for ASP.NET 2025 Q1 and Later

If I have a subscription license that’s active and publish an application to a production environment, all is well.

Scenario case, if my license expires, and I make an update to the application, same version of Telerik controls, but now with an expired license.
If I publish a new version of the application, will it still function without the license key messages?

From what I understand, it will still function and no license messages assuming I don't update the Telerik Controls.

Telerik Image editor does not loads up the image to edit

Hi,

I am using the classic render mode, and I can see some localisation is missing. I am using the Telerik DLL of version 2022.3.913.45
screenshot below:-

Can you please provide the localisation files supported by the Telerik DLL of version 2022.3.913.45? Also, the image editor preview is not working. Is it related to the localisation file not supported by the current version?

https://jam.dev/c/c5cfdd1e-882a-40e5-9185-1cef03a3eceb <- recording

The issue occurs intermittently; sometimes the image loads, and at other times, it does not. Please see the recording for more details, and let me know how I should fix it.

FileExplorer, Document Manager, and Image Manager display an error message when a file upload fails

Hello,

One of our customers reported that they are trying to enhance the security features for file uploads in RadFileExplorer, Document Manager, and Image Manager. Specifically, for SVG files, they want to inspect the file contents for any embedded JavaScript functions. If the file is deemed unsafe, the upload should fail, and an error message should be displayed to the end user.

We have implemented the necessary backend validation and are able to throw an error message. However, we have not found a way to display this error message in the UI. Is there a recommended approach for implementing error message display in this scenario?

Thanks,

Lan
