Silverlight 控制到Datagrid控件中具体每一行的每一列

要求控制前台Datagrid数据列的动画

Silverlight控制前台Datagrid控件中具体每一行的每一列

后台代码：

通过循环访问DataGrid的数据集List<aaa>,可根据业务来控制前台动画动态显示。

   Grid gd = dgTaskList.Columns[0].GetCellContent(aaa) as Grid;
                            if (gd != null)
                            {
                                var res = (Storyboard)gd.Resources["myStoryboard12"];
                                res.Begin();
                            }
