    TimeSpanBox 效果如下,用于选择时间的长度,年最大值99,月最大值11,日最大值30,时最大值23,分最大值59,秒最大值59

    第一步,新建WPF用户TimepanBox

    如何使用:

                <!--不显示年,不现实月,不显示秒,显示按钮,天时分红字,-->

                <Button Content="Set Year" Click="Button_Click"/>
                <TextBlock Margin="0 10 0 0">
                    <Run Text="当前时间:"/>
                    <Run Text="{Binding Year,ElementName=pick}"/>
                    <Run Text="年"/>
                      <Run Text="{Binding Month,ElementName=pick}"/>
                    <Run Text="月"/>

                    <Run Text="分"/>
                      <Run Text="{Binding Secound,ElementName=pick}"/>
                    <Run Text="秒"/>
                </TextBlock>
    
                <x:Code>
                    private void Button_Click(object sender, RoutedEventArgs e)
                    {
                        int tempValue = 0;
                        pick.Day = int.TryParse(this.inputNum.Text, out tempValue) ? tempValue : 0;
                    }
                </x:Code>

    上述控件待完善: 给 Year、Month、Day、Hour、Minite、Secound、负值的时候的CoerceValueCallback

    缺少对应的Year_Change  Month_Change Day_Change Hour_CHange Minite_Change Secound_Chang 等事件

    //本人懒的弄了,UI也没有任何优化

    运行结果

     Bug Fix 初始化时设置时分秒后显示值为0

    原因: UserControl 种的Initial事件种如果包含的BInding是Relative,不能及时更新对应的绑定源,如下

    <TextBox Grid.Column="0" BorderBrush="Transparent" BorderThickness="0" x:Name="txtYear" VerticalContentAlignment="Center"
                     InputMethod.IsInputMethodEnabled="False" TextAlignment="Right" Padding="0,0,1,0"
                     Text="{Binding RelativeSource={RelativeSource Mode=FindAncestor,AncestorType=local:TimeSpanBox},Path=YearText,Mode=TwoWay,UpdateSourceTrigger=PropertyChanged}"/>
