c# - WPF 绑定(bind)到选定的单选按钮

Question

我有一个 Radiobutton 组:

 <RadioButton Name="_CreateGraph" GroupName="MapOrGraph" Content="Create Graph" />
 <RadioButton Name="_CreateMap"   GroupName="MapOrGraph" Content="Create Map"   />

如何将标签的内容绑定(bind)到所选单选按钮的内容？

例如标签应该根据创建的单选框显示 Create Graph 或 Create Map？

Answer 1

<Label Content="{Binding SelectedValue.Content, ElementName=list}"  />

<ListBox x:Name="list" SelectedIndex="1"  >
    <ListBox.ItemContainerStyle>
        <Style TargetType="ListBoxItem">
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="ListBoxItem" >
                        <RadioButton GroupName="a" Content="{TemplateBinding Content}" IsChecked="{Binding IsSelected, RelativeSource={RelativeSource TemplatedParent}  }"  />
                    </ControlTemplate>
                </Setter.Value>
            </Setter>
        </Style>
    </ListBox.ItemContainerStyle>
    <ListBoxItem>Create Graph</ListBoxItem>
    <ListBoxItem>Create Map</ListBoxItem>
</ListBox>

我认为你可以让它比我做的更短。
