Hi Amsm,
Thanks for contacting Syncfusion support.
We have analyzed your requirement at our end. The schedule control does not have the direct support to localize the strings of dialog boxes (i.e. displayed on deleting an item, closing the form and resizing the rows). We have considered this a feature enhancement and added to our feature list. Moreover, the enhancement will be included in our 2018Volume_1_SP1 which will be available in end of March 2018.
Please let us know, if you have any other queries.
Regards,
Arulpriya
