WPF DevExpress怎么绑定ViewModel事件

XAML代码

                    <dxg:GridControl.View>
                        <dxg:TableView x:Name="ProductGridView" ShowGroupPanel="False" AllowColumnFiltering="False">
                            <dxmvvm:Interaction.Behaviors>
                                <dxmvvm:EventToCommand EventName="ValidateCell" Command="{Binding ValidateCell}"  PassEventArgsToCommand="True">
                                </dxmvvm:EventToCommand>
                            </dxmvvm:Interaction.Behaviors>
                        </dxg:TableView>
                    </dxg:GridControl.View>

ViewModel代码

public ICommand<object> ValidateCell { get; private set; }
构造函数()
{
ValidateCell = new DelegateCommand<object>(Edit);
}

        public void Edit(object arg)
        {

        }
