telerik:RadEditor - undefined error when clicking on controls

[Chris Christensen]

We're using a telerik:RadEditor and have just updated to .Net 4.7.2.

When we click on some of the controls, e.g. the "strip formatting" control, then we sometimes (not always) get the following error shown in the Browser's console "Cannot read property 'trim' of undefined".

We're running version 2014.1.403.35 of the Telerik.Web.UI.  We know that there are newer versions available but don't want to have to upgrade if this is not required.

Two errors are as follows:

Hi Chris,

Thank you for reporting this error!

To be frank, you are the first to report it and we are not aware of it,

My recommendation is to test the latest version and upgrade to it, because this will ensure:

• support for .NET 4.7.2 introduced in R2 2018 (version 2018.2.516) see here.
• support for the latest browsers
• security updates
• stability.

You can find upgrade instructions here.

Please test and let me know how it goes.

Regards,
Rumen

Hi Rumen

Updating to the later version solved the problem - thank you so much.  However, the application is essentially in maintenance mode and our Telerik licence has expired. Since we're not doing any functional changes to the application, just fixing bugs and, as in this case, updating the .NET framework, is there a cheaper license to be had for applications that are in maintenance mode?

Thanks

[Rumen]

Thank you for your confirmation that the problem is fixed in the latest version!

 

My colleagues from the sales team will contact you and offer you an upgrade path.

I got some issue with radeditor.

it was working fine with targetframwork 4.0. when I changed to 4.8 it got script error and not working properly. 
i used latest version 2020.3.1021.35

[Rumen]

Hi Mu,

Happy New Year 2021!

Version 2020.3.1021.35 is built against .NET 3.5.

Please update the Telerik.Web.UI.dll and the other Telerik assemblies in the bin folder with the ones placed in the Bin45 folder of the R3 2020 SP1 (version 2020.3.1021) installation. You can download for example the Telerik_UI_for_ASP.NET_AJAX_2020_3_1021_Dev_hotfix.zip from https://www.telerik.com/account/product-download?product=RCAJAX and obtain the dlls from the Bin45 folder in the root of the archive.

If the problem still persists after the dlls update, please provide a simple working project which demo the error so that I can investigate it further.

Best Regards,
Rumen
