Hi Harald , 
You can achieve your requirement for maintaining the Grouping while changing the ItemsSource by setting the AutoGenerateColumnsMode like below, 
 




<syncfusion:SfDataGrid 
                x:Name="SampleDataGrid"  
                AutoGenerateColumnsMode="RetainOld" 
                ItemsSource="{Binding GridDataSource}" 
                AutoExpandGroups="True" 
                AutoGenerateColumns="True"/>
