Hello Vitor,
If you want to display the BusyIndicator when grouping and expanding the groups, you can use the following event handlers, which seem to be working fine at my end:
I've attached a modified version of my sample project to demonstrate this. Could you verify that you're using the same approach?

If you want to display the BusyIndicator when grouping and expanding the groups, you can use the following event handlers, which seem to be working fine at my end:
public MainWindow(){ InitializeComponent(); DataContext = new ViewModel(); var view = (this.DataContext as ViewModel).View; view.ItemsLoading += View_ItemsLoading; view.ItemsLoaded += View_ItemsLoaded; this.RadGridView.Grouping += RadGridView_Grouping; this.RadGridView.Grouped += RadGridView_Grouped; this.RadGridView.GroupRowIsExpandedChanging += RadGridView_GroupRowIsExpandedChanging; this.RadGridView.GroupRowIsExpandedChanged += RadGridView_GroupRowIsExpandedChanged;}private void RadGridView_GroupRowIsExpandedChanged(object sender, Telerik.Windows.Controls.GridView.GroupRowEventArgs e){ this.busyIndicator.IsBusy = false;}private void RadGridView_GroupRowIsExpandedChanging(object sender, Telerik.Windows.Controls.GridView.GroupRowCancelEventArgs e){ this.busyIndicator.IsBusy = true;}private void RadGridView_Grouped(object sender, GridViewGroupedEventArgs e){ this.busyIndicator.IsBusy = false;}private void RadGridView_Grouping(object sender, GridViewGroupingEventArgs e){ this.busyIndicator.IsBusy = true;}private void View_ItemsLoaded(object sender, VirtualQueryableCollectionViewItemsLoadedEventArgs e){ this.busyIndicator.IsBusy = false;}private void View_ItemsLoading(object sender, VirtualQueryableCollectionViewItemsLoadingEventArgs e){ this.busyIndicator.IsBusy = true;}I've attached a modified version of my sample project to demonstrate this. Could you verify that you're using the same approach?
