WPF时间长度自定义选择控件TimeSpanBox
以下控件采用https://www.cnblogs.com/cssmystyle/archive/2011/01/17/1937361.html部分代码
以下控件采用https://www.cnblogs.com/xiaomingg/p/11180355.html部分代码
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：
xmlns:local="clr-namespace:TimeEditerDemo"
.... <!--不显示年，不现实月，不显示秒，显示按钮，天时分红字，-->
<local:TimeSpanBox x:Name="pick" Height="25" TitleBrush="Red"
IsYearVisible="False" IsMonthVisible="False" IsSecoundVisible="False" UpDownBtnVisible="Visible"/>
<TextBox x:Name="inputNum"/>
<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="{Binding Day,ElementName=pick}"/>
<Run Text="日"/>
<Run Text="{Binding Hour,ElementName=pick}"/>
<Run Text="时"/>
<Run Text="{Binding Minutes,ElementName=pick}"/>
<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}"/>
