我无法在单选按钮上映射网格中的数据，请告诉我缺少的位置

Add CommandParameter=“{Binding}”，以便您可以在视图模型中获取案例中的整个对象（Lead）。然后可以将此对象设置为选定项。所以你可以像这样修改你的代码

 <RadioButton Content="Test" Style="{StaticResource SemiRadioButtonStyle}" GroupName="Lead"
                                     IsEnabled="True" Command="{Binding Path= CheckedCommand}"  CommandParameter="{Binding}" IsChecked="{Binding InboundChecked,Mode=TwoWay}"/>

然后在您的代码中，您可以将CommandParameter强制转换为Lead，并将此对象设置为SelectedLead

您是否能够通过命令绑定检索命令参数？我不明白您的意思，如果我将调试器放在方法上，我无法获取它。。请联系我skype如果你能帮助我，我的id是bs24neeraj，这是紧急的，我必须提交代码今天
