RadioButtonList绑定单选题
怎样能让RadioButtonList同时绑定显示数据库里的4个字段值的？
并按以下格式排列？
○A 字段一
○B 字段二
○C 字段三
○D 字段四
就是单选题 答案从数据库中绑定，RadioButtonList 在Repeater里面

[解决办法]
- C# code
protected void Repeater1_ItemDataBound(object sender, RepeaterItemEventArgs e) { RadioButtonList Radiobuttonlist1 = e.Item.FindControl("Radiobuttonlist1") as RadioButtonList; Radiobuttonlist1.Items.Add(new ListItem("A" + DataBinder.Eval(e.Item.DataItem, "字段1").ToString(), "A")); Radiobuttonlist1.Items.Add(new ListItem("B" + DataBinder.Eval(e.Item.DataItem, "字段2").ToString(), "B")); Radiobuttonlist1.Items.Add(new ListItem("C" + DataBinder.Eval(e.Item.DataItem, "字段3").ToString(), "C")); Radiobuttonlist1.Items.Add(new ListItem("D" + DataBinder.Eval(e.Item.DataItem, "字段4").ToString(), "D")); }
