Hello Jae,

Could you please provide more details on the exact approach you've taken for switching the languages at runtime?

It would really be of help if you could open a new support ticket and send over a small sample project that demonstrates the issue so that I can investigate and further assist you.

Thank you in advance for your cooperation on the matter.

Hello,

A similar scenario has been discussed in this forum thread. As suggested by my colleagues there, the RadDocking control saves only the Header text and the dynamic resource reference is lost in the process.

To modify this behavior, you should handle the ElementLoaded event of the control and update the header content there similarly to the approach my colleague has demonstrated in this reply.

I hope you find this helpful. If you need any further assistance, please let me know.
