How to customize the scrollbar style in CheckboxFilterControl of SfDataGrid?

My third question is changing scrollbar style in this popup because I am using fixed size in this popup. And scrollbar is automatically opening if popup have a lot of item. So, it is working okay but I want to change the style of this scrollbar.

To customize the scrollbar style in FilterPopUp can be achieved by customizing the ScrollViewer style in CheckboxFilterControl. Refer to the below code snippet,


<Style TargetType="{x:Type syncfusion:CheckboxFilterControl}">

     <Setter Property="SearchOptionVisibility" Value="Collapsed"/>

     <Setter Property="ItemTemplate" Value="{StaticResource CheckboxFilterControlItemTemplate}"/>

     <Setter Property="Template">

         <Setter.Value>

             <ControlTemplate TargetType="{x:Type syncfusion:CheckboxFilterControl}">

<ItemsControl x:Name="PART_ItemsControl"

                                                          Height="{TemplateBinding Height}"

                                                          HorizontalAlignment="Stretch"

                                                          VerticalAlignment="Stretch"

                                                          IsTabStop="false"

                                                          HorizontalContentAlignment="Stretch"

                                                          VerticalContentAlignment="Stretch"

                                                          ItemTemplate="{TemplateBinding ItemTemplate}"

                                                          ItemsSource="{TemplateBinding ItemsSource}"

                                                          KeyboardNavigation.TabNavigation="Continue"

                                                          Visibility="{Binding IsItemSourceLoaded,
