我如何能夠在radiobuttonlist的DataTextField中給出兩個字符串？

Question

這裏的「名稱」和「規格」是我的表的字段，我想在DataTextField中顯示這​​兩個字段。我試過上面的代碼：

RadioButtonList1.DataSource = dt; 
RadioButtonList1.DataTextField = "name"; 
RadioButtonList1.DataTextField = "specification"; 
RadioButtonList1.DataBind(); 

但它不工作。

Answer 1

RadioButtonList1.Items.Clear(); 

foreach(var row in dt.Rows) 
{ 
    var txt = row["name"].ToString() + " " + row["specification"].ToString(); 
    var val = row["id"].ToString(); 
    var item = new ListItem(txt,val); 
    RadioButtonList1.Items.Add(item); 
} 

Answer 2

您將需要在項目數據綁定事件上填充字段或從dt創建新的組合列;

var newDT = (from r in dt 
      select new 
      { 
       ID = r.ID, 
       NameAndSpec = r.name + ", " + r.specification 
      } 
      );
