public MainWindow()
    System.Threading.Thread.CurrentThread.CurrentUICulture = new System.Globalization.CultureInfo("de");

Localize when the resource file is present in different assembly or different namespace

When the resource file is located at different assembly or namespace, then you can let treegrid know by using GridResourceWrapper.SetResources method.

public MainWindow()
    System.Threading.Thread.CurrentThread.CurrentUICulture = new System.Globalization.CultureInfo("de-DE");
    Syncfusion.UI.Xaml.Grid.GridResourceWrapper.SetResources("Assembly_name", "namespace_name");
