I found page http://docs.telerik.com/windows-universal/controls/raddatagrid/localizationkeys. There is a list of localization keys. But it is not completed. There is a lack of following keys: NotEqualTo, ApplyFilterButton. There is CaseSensitiveMode key and it`s ok but when I`m using localized datagrid in my app there are not localized 'on'/'off' info in tooltip. Is there a possiblitity to localize these strings in different way? It`s very important for my enterprise app...
