Hi Yuriy,
Thanks for your interests in Syncfusion products.
Yes we have implemented this feature in our latest source. For more information about your localization for our controls, kindly go through our online documentation.
http://help.syncfusion.com/ug_72_new/toolswpf/LocalizationSupport.htmlOnce you create the satellite assembly, send us for signing the assemblies by creating new Direct-Trac incidents.
Please let us know if you have any queries.
Regards,
Bala.
