Hello, I want to reference the default template of the MilestoneContainer but I don't achieve this.
the goal is to use the default template and override when a dataTrigger is firing
I try to only define the data trigger
<Style BasedOn="{StaticResource ResourceKey={x:Type telerik:MilestoneContainer}}" TargetType="{x:Type telerik:MilestoneContainer}">

                    <Style.Triggers>
                        <DataTrigger Binding="{Binding Converter={StaticResource ObjectAndTypeToVisibilityConverter}, ConverterParameter={x:Type vm:GanttTaskModelePlanningFamille}}" Value="True">
                            <Setter Property="Template">
                                <Setter.Value>
                                    <ControlTemplate>
                                        <Rectangle Width="3"
                                                   Height="24"
                                                   Fill="{TemplateBinding Background}" />
                                    </ControlTemplate>
                                </Setter.Value>
                            </Setter>
                        </DataTrigger>
                    </Style.Triggers>
                </Style>
It's no working, trigger have no action
I try to reference the default template in my style definition (to force the trigger)
<Setter Property="Template" Value="{StaticResource MilestoneContainerTemplate}" />
But still not working, the resource is not know
I also try to do reference at resource using the telerik dll, but the import failed (build failed)
<ResourceDictionary Source="pack://application:,,,/Telerik.Windows.Controls.GanttView;component/Telerik.Windows.Controls.GanttView.xaml" /> 

Have you any idea how I can solve my problem ?

Thanks

Hi Julian,

I've created a sample project which demonstrates the wokring DataTriger without a parameter. Please check if this example works for you.

I hope it helps.

Hi Julien,

I guest you are using Xaml binaries and this is the cause of the error
In the attached project the implicit styles approach and NoXaml binaries are used. In that case you  don't need to copy the whole styles and all resources because they have been inherited from the merged resource dictionaries. I've updated the project where I've included the GanttView resources.

Please take a look and let me know if this helps.
