Why the GroupAdded event not get fired while dragging a column to the GroupDropArea?

Platform: ASP.NET Web Forms (Classic) |
Control: GridGroupingControl


While dragging a column to the GroupDropArea by default the GroupAdded event won't get fired, but the Engine.PropertyChanged event get fired. Because there is some Performance issue in firring the GroupAdded event. Please refer the below code snippet to trigger the Engine.PropertyChanged event:


this.GridGroupingControl1.Engine.PropertyChanged += new DescriptorPropertyChangedEventHandler(Engine_PropertyChanged);

protected void Engine_PropertyChanged(object sender, DescriptorPropertyChangedEventArgs e)


Response.Write("Property chnaged");



AddHandler GridGroupingControl1.Engine.PropertyChanged, AddressOf Engine_PropertyChanged

Protected Sub Engine_PropertyChanged(ByVal sender As Object, ByVal e As DescriptorPropertyChangedEventArgs)

Response.Write("Property chnaged")

End Sub
