This demo shows how to localize RadDataPager using global resource files. You need to copy your language file (for instance RadDataPager.Main.fr-FR.resx) and RadDataPager.Main.resx file to App_GlobalResouces folder and then set the desired culture via the Culture property.
You can choose the desired language using the country flags in the RadDataPager template. The currently selected culture is displayed below the RadListView.
