Vertical scroll using mouse wheel

I can't resolve this.  If I set ManipulationMode="System" works with tactil, but not with mouse wheel. And if I set IsHitTestVisible="false", then I can use mouse wheel too, but its not a solution for me, becouse i need interact with control.

Thank you!

Hi Galobart,   
Thanks for the update.   
We have checked and by default, the vertical scrolling by mouse wheel is working fine in SfTreeGrid without any issues. We have set the ManipulationMode as System in grid and checked the reported scenario. The mouse wheel and touch scrolling are working properly from our side.     
Please let us know the requirement clearly so that we can provide solution to meet your requirement.

I checked too and yes, its work by default.

Sorry for my poor explanation.  

The TreeGrid is inside a ScrollViewer, and the TreeGrid Control prevent scrolling. ¿There are any way to avoid it?

<ScrollViewer Grid.Row="1" Padding="15,30,15,15" VerticalScrollBarVisibility="Auto">
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
<RowDefinition Height="*" />
<ComboBox ... />
<TextBox Grid.Row="1" ... />
<Line Grid.Row="1" ... />
<TextBlock Grid.Row="2" ... />
<syncfusion:SfTreeGrid x:Name="sfTreeGrid" ChildPropertyName="ReportsTo" Grid.Row="3" AllowSorting="False" AutoExpandMode="AllNodesExpanded"
ParentPropertyName="Id" Margin="0,15,0,0" AutoGenerateColumns="False" AllowAutoSizingExpanderColumn="False"
SelectionMode="None" FontSize="14" ItemsSource="{Binding Path=Perfiles}" Background="{ThemeResource ApplicationPageBackgroundThemeBrush}"                                              
ScrollViewer.HorizontalScrollBarVisibility="Hidden" ScrollViewer.VerticalScrollBarVisibility="Hidden">
<syncfusion:TreeGridTextColumn x:Name="sfTreeGridDescripcion" x:Uid="sfTreeGridDescripcion" MappingName="Descripcion" Width="176">
<syncfusion:TreeGridTemplateColumn x:Name="sfTreeGridSelect" x:Uid="sfTreeGridSelect" MappingName="Select" Width="60">
