WPF的数据绑定

当你写

<Label Name="myLabel" Content="{Binding Path=Name}" />

意味着你的绑定是myLabel.DataContext.Name, 而不是myLabel.Name.

The XAML in WPF is just a pretty user interface to display and interact with the actual data, otherwise known as the DataContext.

而诸如另外的绑定方式如：

<TextBox Name="TextBox1" Height="30" Text="{Binding ElementName=ColorPicker1, Path=SelectedColorText}"
       Background="{Binding ElementName=ColorPicker1, Path=SelectedColor, Converter={StaticResource colorToSolidBrush}}"/>

The purpose of other binding sources (RelativeSource, ElementName, etc) is to point to another property that doesn't exist in the current control's DataContext
