  • WPF DataGrid 对行中单元格的访问

    第一种方法:

    dataGridFirst.PreparingCellForEdit += new EventHandler<DataGridPreparingCellForEditEventArgs>(dataGridFirst_PreparingCellForEdit);
    
      void dataGridFirst_PreparingCellForEdit(object sender, DataGridPreparingCellForEditEventArgs e)
      {
      Suppose this list(get and set values)
      //var myValue = dataGrid1.SelectedItem[0].ToString(); 
      ClientsList selectedrow = ClientsList)dataGridFirst.SelectedItem;
      string Clientname = selectedrow.Name;
      int Clientid = selectedrow.ClientID;
      
      }

    第二种方法:

    private void dataGrid_SelectionChanged(object sender, SelectionChangedEventArgs e) 
            {     
                DataGrid dataGrid = sender as DataGrid;  
                if (e.AddedItems!=null && e.AddedItems.Count>0)  
                {       
                    // find row for the first selected item     
                    DataGridRow row = (DataGridRow)dataGrid.ItemContainerGenerator.ContainerFromItem(e.AddedItems[0]);    
                    if (row != null)   
                    {          
                        DataGridCellsPresenter presenter = GetVisualChild<DataGridCellsPresenter>(row);   
                        // find grid cell object for the cell with index 0       
                        DataGridCell cell = presenter.ItemContainerGenerator.ContainerFromIndex(0) as DataGridCell;      
                        if (cell != null)     
                        {             
                            Console.WriteLine(((TextBlock)cell.Content).Text);         
                        }     
                    }   
                }
            }
    
    static T GetVisualChild<T>(Visual parent) where T : Visual
            { 
                T child = default(T);
                int numVisuals = VisualTreeHelper.GetChildrenCount(parent); 
                for (int i = 0; i < numVisuals; i++) 
                { 
                    Visual v = (Visual)VisualTreeHelper.GetChild(parent, i);
                    child = v as T; 
                    if (child == null)
                        child = GetVisualChild<T>(v);
                    if (child != null)
                        break;
                }
                return child;
            }
