1）增加事件

2）增加对象获取

1）事件代码

Datagrid 增加事件 MouseDoubleClick="dataGrid_MouseDoubleClick"

  private void dataGrid_MouseDoubleClick(object sender, System.Windows.Input.MouseButtonEventArgs e)




         {



             DataGrid datagrid = sender as DataGrid;



             Point aP = e.GetPosition(datagrid);



             IInputElement obj = datagrid.InputHitTest(aP);



             DependencyObject target = obj as DependencyObject;











             while (target != null)



             {



                 if (target is DataGridRow)



                 {



                     var s = this.dataGrid.SelectedItem;



                 }



                 target = VisualTreeHelper.GetParent(target);



             }



         }

2）获得属性

直接转换对象

对象类 s = （对象类） this.dataGrid.SelectedItem; 就可以了

   var s = this.dataGrid.SelectedItem;

WPF DataGrid 双击行 获得绑定数据
