各种情况下 Data Binding 总结

绑定到另一个控件的属性

<StackPanel>
    <TextBox x:Name="theTextBox"/>
    <TextBlock Text="{Binding Text, ElementName=theTextBox}"/>
</StackPanel>

上面这个例子，TextBlock的内容绑定了TextBox，当在TextBox里输入文本是，TextBlock也同时显示

绑定到 RelativeSource

<ListBox ItemsSource="{Binding MyDataSrc}" Width="200" Padding="0">
    <ListBox.ItemTemplate>
        <DataTemplate>
            <Grid Width="{Binding Path=ActualWidth, RelativeSource={RelativeSource Mode=FindAncestor, AncestorType=ListBoxItem}}">
                <Button Content="{Binding}"/>
            </Grid>
        </DataTemplate>
    </ListBox.ItemTemplate>
</ListBox>

{Binding Path=xxx, RelativeSource={RelativeSource Self}}
{Binding Path=xxx, RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type typeXXX}}}
{Binding Path=xxx, RelativeSource={RelativeSource TemplatedParent}}
{TemplateBinding Path=xxx}
