如何在datagrid中加入RadioButtonList,并databanding数据，比如选择题A\B\C\D四个项，列出10题。

先加一个样板列，里面放radiobuttonlist
在itembound事件里写
if e.item.itemindex<>-1 then
    dim r as radiobuttonlist
    r=e.item.cell(0).findcontrol("radiobuttonlist1")
    r.items.add("a")
    r.items.add("b")
....

RadioButtonList如何DataBinding数据啊
重载DataGrid的ItemCreated,
下面是一段通过的代码,DT和iCount是全局变量public void OnItemCreate(object sender,DataGridItemEventArgs e)
{   RadioButtonList list=(RadioButtonList)e.Item.Cells[2].FindControl("select_index");
   if(list!=null && DT!=null && iCount<DT.Rows.Count)
   {
list.SelectedIndex=Convert.ToInt32(DT.Rows[iCount]["state_index"]);
iCount++;
   }
}
