MVVM Silverlight 5 Datagrid MVVM 鼠标双击事件

近日在Silverlight 5中用到了要在Datagrid鼠标双击事件 ，本来很多学习资料 但是由于用的是MVVM模式。所以一开始一头雾水，后来用了比较简便的方式予以实现，仅供参考，也请各位大侠指点。

具体代码见下：

1、页面XAML代码

<sdk:DataGridTextColumn Binding="{Binding UpdateDate }"   Header="更新时间" />

            </sdk:DataGrid.Columns>

            //触发器

            <i:Interaction.Triggers>

                <i:EventTrigger EventName="MouseLeftButtonUp" >

                    <cmd:EventToCommand Command="{Binding OpenEditwindowCommand}"

                                        CommandParameter="{Binding SelectedItem,ElementName=dgMembers}" />

                </i:EventTrigger>

            </i:Interaction.Triggers>

        </sdk:DataGrid>

当然要添加引用：

                 xmlns:cmd="clr-namespace:galaSoft.MvvmLight.Command;assembly=galaSoft.MvvmLight.Extras.SL5"

                 xmlns:i="clr-namespace:System.Windows.Interactivity;assembly=System.Windows.Interactivity"

2、viewmodel代码

private DateTime _clickTs;

#region Command定义

        public ICommand OpenEditwindowCommand { get; private set; }

#endregion

public Testviewmodel()

{

       _clickTs = DateTime.Now;

      OpenEditwindowCommand = new RelayCommand<object>(OpenEditwindow);

}

private void OpenEditwindow(object obj)

{

            DateTime Now = DateTime.Now;

            if (Now.Subtract(_clickTs).TotalMilliseconds <= 200)//此处的时间都是毫秒哦

            {

                //此处添加您要实现的功能.

            }

            else

            {

                _clickTs = Now;

            }

}
