WPF CommandParameter传多个能数到ViewModel?-急，在线等

覃祖甘 2013-08-21 11:22:39

我现在想传两个控件到一ViewModel，可是ViewModel的方法参数一直为null，取不到任何值。
有什么好的办法吗？
我的源码是这样的：



    <Window.Resources>

        <local:DataConverter x:Key="dataConverter"/>

    </Window.Resources>



<Button Header="添加用户" Icon="Images\Green.png" LargeIcon="Images\GreenLarge.png" x:Name="BtnAddUser" Command="{Binding AddUserCommand}">

                        <Button.CommandParameter>

                            <MultiBinding Converter="{ StaticResource ResourceKey=dataConverter}" Mode="TwoWay">

                                <MultiBinding.Bindings>

                                    <Binding ElementName="BtnAddUser"/>

                                    <Binding ElementName="dockManager "/>

                                </MultiBinding.Bindings>

                            </MultiBinding>

                        </Button.CommandParameter>

                        

</Button>
