Using Telerik excellent RadGrid in an Asp.Net Web Application and need to translate my website into another language other than English. In this case German so first download the resource file from Telerik currently located here:-
Global resources for RadGrid
Pop the file into App_GlobalResources folder or create one if you don't already have it:-

Here I am using the RadGrid.Main.resx (English) and RadGrid.Main.de.resx (German - all versions)
Now it does seem to pick up the language setting of the users browser settings so just do the switch in code (normally under Page_Load:-
if (!IsPostBack)
{
RadGrid.Culture = System.Globalization.CultureInfo.CurrentCulture
}
