圍繞展開的行設置邊框

Question

我使用帶事件的devexpress xtragrid（C＃winforms）將主要行動態綁定到詳細行。當我展開主要行時，我正在設置主要和詳細信息行的邊框。當主行被展開時，我想要一行藍色框與其明細行一起使用，以使它突出顯示給用戶。

您可以使用該方法的基礎上，處理GridControl.Paint事件完成任務：

gridControl1.DataSource = Repository.GetOrders(); 
// Some Visual Options for details 
gridView1.LevelIndent = 0; 
gridView1.OptionsDetail.ShowDetailTabs = false; 
gridView1.OptionsDetail.AllowOnlyOneMasterRowExpanded = true; 
// 
gridControl1.Paint += gridControl1_Paint; 
//... 
void gridControl1_Paint(object sender, PaintEventArgs e) { 
    var viewInfo = gridView1.GetViewInfo() as GridViewInfo; 
    foreach(var rowInfo in viewInfo.RowsInfo) { 
     if(gridView1.GetMasterRowExpanded(rowInfo.RowHandle)) 
      e.Graphics.DrawRectangle(Pens.Blue, rowInfo.TotalBounds); 
    } 
} 

數據類：

public static class Repository { 
    public static List<Order> GetOrders() { 
     return new List<Order> { 
      new Order(){ Id=0, Date = DateTime.Now.AddDays(-1), 
       Items = new List<OrderItem>{ 
        new OrderItem(){ Id=0, Name="A"}, 
        new OrderItem(){ Id=1, Name="B"}, 
       } 
      }, 
      new Order(){ Id=1, Date = DateTime.Now, 
       Items = new List<OrderItem>{ 
        new OrderItem(){ Id=0, Name="A"}, 
        new OrderItem(){ Id=1, Name="B"}, 
        new OrderItem(){ Id=1, Name="C"}, 
       } 
      } 
     }; 
    } 
} 
public class Order { 
    public int Id { get; set; } 
    public DateTime Date { get; set; } 
    public List<OrderItem> Items { get; set; } 
} 
public class OrderItem { 
    public int Id { get; set; } 
    public string Name { get; set; } 
}
