我想添加另一列到我的網格控件中：Selection = new bool（）。它將被添加到網格中，但我無法更改其行的值。我如何添加到我的網格可以更改其值的列

Answer 1

使用非匿名類的簡單示例。

public class MyLovelyClass 
{ 
    public Int32 Number { get; set; } 
    public bool Selection { get; set; } 
} 

var packs = from r in new XPQuery<Roll>(session) 
      select new MyLovelyClass() 
      { 
       Number = r.number     
      }; 
gcPack.DataSource = packs;
