Hello,

You can manually set the Orientation of the StackPanel that contains the TextBlocks to vertical. It's Name is EditPanel.

Hope this helps.

I would like to do something similar with the XamMonthView. The above solution seems to not work since IsSingleLineDisplay is set to true for the ActivityPresenter when using XamMonthView? Please advise, thanks.

Hello,

Thank you for your feedback. I am glad that you resolved your issue and I believe that other community members may benefit from this as well.

Thanks again.

Thanks, works great. The only change I made was to bind to the description and to add a ' - ' when displaying on a single line:

                            <TextBlock Text=" - ">
                                    <TextBlock.Style>
                                        <Style TargetType="TextBlock">
                                            <Style.Triggers>
                                                <DataTrigger Binding="{Binding Path=IsSingleLineDisplay, RelativeSource={RelativeSource TemplatedParent}}" Value="False">
                                                    <Setter Property="Visibility" Value="Collapsed"/>
                                                </DataTrigger>
                                                <DataTrigger Binding="{Binding Description}" Value="">
                                                    <Setter Property="Visibility" Value="Collapsed"/>
                                                </DataTrigger>
                                                <DataTrigger Binding="{Binding Description}" Value="{x:Null}">
                                                    <Setter Property="Visibility" Value="Collapsed"/>
                                                </DataTrigger>
                                            </Style.Triggers>
                                        </Style>
                                    </TextBlock.Style>
                                </TextBlock>
                          <TextBlock Text="{Binding Description}"/>
