wpf datepicker控件隐藏星期

要隐藏 WPF DatePicker 控件中的星期，你可以使用 DatePicker 控件的默认样式并对其进行更改。以下是隐藏星期的样式代码示例：

<Style TargetType="DatePicker">
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="DatePicker">
                <StackPanel>
                    <Grid>
                        <Grid.ColumnDefinitions>
                            <ColumnDefinition Width="*" />
                            <ColumnDefinition Width="Auto" />
                        </Grid.ColumnDefinitions>
                        <DatePickerTextBox x:Name="PART_TextBox"
                            Grid.Column="0"
                            BorderThickness="0"
                            Text="{Binding Path=SelectedDate, StringFormat='d', RelativeSource={RelativeSource TemplatedParent}, Mode=TwoWay}" />
                        <Button Grid.Column="1" Content="▼" VerticalAlignment="Bottom" />
                    </Grid>
                    <Calendar x:Name="PART_Calendar"
                        DisplayMode="Month"
                        SelectedDate="{Binding Path=SelectedDate, RelativeSource={RelativeSource TemplatedParent}, Mode=TwoWay}"
                        Visibility="Collapsed" />
                </StackPanel>
                <ControlTemplate.Triggers>
                    <Trigger Property="IsDropDownOpen" Value="True">
                        <Setter TargetName="PART_Calendar" Property="Visibility" Value="Visible" />
                    </Trigger>
                </ControlTemplate.Triggers>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

将此样式应用于 DatePicker 控件，它将隐藏星期并只显示选定日期的文本框和下拉按钮。
