整理WPF中Binding的写法：

XMAL中控件绑定的一定要是依赖属性

提示：顺便提一下TextBlock如何设置绑定命令，因为TextBlock没有Command这个依赖属性，所以要采用其他途径

学习内容1：

提示：下面是一些常用的绑定写法

 <Button Content="{Binding DataTime}"/>   <Button x:Name="btn" Content="{Binding DataTime,Mode=OneTime}"/>   <Button Content="{Binding DataTime,UpdateSourceTrigger=PropertyChanged}"/>   <Button Content="{Binding DataTime,Converter={StaticResource ConvertResource},ConverterParameter=btn1}"/>   <Button Content="{Binding ElementName=btn,Path=Content}"/>   <Button Content="{Binding RelativeSource={RelativeSource Mode=Self},Path=Tag}" Tag="MyTag"/>   <Button Content="{Binding RelativeSource={RelativeSource Mode=FindAncestor,AncestorType=Window},Path=Content}"/>   <Button Content="{Binding RelativeSource={RelativeSource Mode=FindAncestor,AncestorType=Window},Path=Content}"/>   <Button Content="{Binding RelativeSource={RelativeSource Mode=FindAncestor,AncestorLevel=2},Path=Content}"/>   <Button Content="{Binding RelativeSource={RelativeSource Mode=TemplatedParent},Path=Content}"/>

学习内容2：

提示：下面是TextBlock绑定命令的一种写法

 <TextBlock   HorizontalAlignment="Right" Text="" Style="{StaticResource CloseBtnStyle}"> <TextBlock.InputBindings>    <MouseBinding Command="{Binding CloseCommand}"      CommandParameter="{Binding Path=.,RelativeSource={RelativeSource AncestorType=Window}}"MouseAction="LeftClick">   </MouseBinding>  </TextBlock.InputBindings></TextBlock>

其中{Bingding Path=.,xxxx}表示绑定到自身，等价于{Bingding ., xxxx}
