silverlight 双击事件 GLenn

DataGrid 没有双击事件所以要自己写。看了很多双击事件 都是用time 什么的。。  好不用意找到了个简单的。自己整理记录下。

xaml:

 <data:DataGrid x:Name="MainDataGrid" LoadingRow="Grid_LoadingRow" UnloadingRow="Grid_UnloadingRow"  IsReadOnly="True">
                <data:DataGrid.Columns>
                    <data:DataGridTextColumn Binding="{Binding TopicGuid, Mode=TwoWay}" Header="话题ID" Width="0.3*"/>
                    <data:DataGridTextColumn Binding="{Binding TopicStartDate, Mode=TwoWay}" Header="起始时间" Width="0.5*"/>
                    <data:DataGridTextColumn Binding="{Binding TopicEndDate, Mode=TwoWay}" Header="结束时间" Width="0.5*"/>
                    <data:DataGridTextColumn Binding="{Binding TopicOrganizer, Mode=TwoWay}" Header="发起人" Width="0.5*"/>
                </data:DataGrid.Columns>
 </data:DataGrid>

cs:

private void Grid_LoadingRow(object sender, DataGridRowEventArgs e)
        {
            e.Row.MouseLeftButtonUp += Row_MouseLeftButtonUp;
        }
        private void Grid_UnloadingRow(object sender, DataGridRowEventArgs e)
        {
            e.Row.MouseLeftButtonUp -= Row_MouseLeftButtonUp;
        }

        private void Row_MouseLeftButtonUp(object sender, MouseButtonEventArgs e)
        {
            TimeSpan t = DateTime.Now.TimeOfDay;
            if (this.MainDataGrid.Tag != null)
            {
                TimeSpan oldT = (TimeSpan)this.MainDataGrid.Tag;
                if (t != oldT && (t - oldT) < TimeSpan.FromMilliseconds(300))
                {
                     MessageBox.Show("双击事件");
                }
            }
            this.MainDataGrid.Tag = t;
        }
