wpf - Wpf Material Design 日期时间选择器

Question

我使用了 XAML Toolkit 中的 Material Design 中的代码，该代码位于代码下方。

<StackPanel Orientation="Horizontal">
    <TextBlock Text="{Binding Date, StringFormat={}{0:yyyy-MM-dd HH:mm:ss}}" VerticalAlignment="Center" FontSize="24" />
    <Button Margin="8 0 0 0" Content="..." Command="{x:Static materialDesign:DialogHost.OpenDialogCommand}" 
            materialDesign:DialogHost.DialogOpenedAttached="CombinedDialogOpenedEventHandler" materialDesign:DialogHost.DialogClosingAttached="CombinedDialogClosingEventHandler">
        <Button.CommandParameter>
            <Grid Margin="-1">
                <Grid.RowDefinitions>
                    <RowDefinition Height="*" />
                    <RowDefinition Height="Auto" />
                </Grid.RowDefinitions>
                <StackPanel Grid.Row="0" Orientation="Horizontal">
                    <Calendar x:Name="CombinedCalendar" Margin="-1 -4 -1 0" />
                    <materialDesign:Clock x:Name="CombinedClock" DisplayAutomation="CycleWithSeconds" Is24Hours="True" />
                </StackPanel>
                <StackPanel Grid.Row="1" Margin="8" HorizontalAlignment="Right" Orientation="Horizontal">
                    <Button Command="{x:Static materialDesign:DialogHost.CloseDialogCommand}" CommandParameter="0" Style="{DynamicResource MaterialDesignFlatButton}">
                        CANCEL
                    </Button>
                    <Button Command="{x:Static materialDesign:DialogHost.CloseDialogCommand}" CommandParameter="1" Style="{DynamicResource MaterialDesignFlatButton}">
                        OK
                    </Button>
                </StackPanel>
            </Grid>
        </Button.CommandParameter>
    </Button>
</StackPanel>

但是我有很多错误。我无法修复错误，因为我是 wpf 的新手。

错误：

如何修复错误？

编辑：在materialDesign前缀被映射后，它给出了另一个错误：

“无法从文本‘CombinedDialogOpenedEventHandler’创建‘DialogOpenedAttached’。” 行号'21'和行位置'48'。'"

materialDesign前缀应映射到http://materialdesigninxaml.net/winfx/xaml/themesXAML 命名空间：

xmlns:materialDesign="http://materialdesigninxaml.net/winfx/xaml/themes"
