各位知道使用RadioButtonList的进来接分

[ajuni194]

使用RadioButtonList的问题，要实现调查问卷的前台显示，问几次了，居然没能碰到有效的方案，得到zpisgod(GOD)兄思路的指点，自己写一段代码：
........
<asp:datalist id="question" ">
<ItemTemplate>

<%#DataBinder.Eval(Container.DataItem,"Polls_Question")%>

<asp:RadioButtonList id=RadioButtonList1 runat="server" DataSource='<%# GetDataSoure(DataBinder.Eval(Container.DataItem,"Polls_Qutetion_ID").ToString())%>' >
</asp:RadioButtonList＞ </ItemTemplate>
</asp:datalist>

注意有个GetDataSoure的函数是我写在后台代码里面的：
public ArrayList GetDataSoure(string _ID)
{
string conntr=System.Configuration.ConfigurationSettings.AppSettings["connstr"].ToString();

string SQL="SELECT Polls_Option1,Polls_Option2,Polls_Option3,Polls_Option4,Polls_Option5 FROM Polls_Question WHERE Polls_Qutetion_ID='"+_ID.Trim()+"'";

ArrayList ar=new ArrayList();
SqlConnection conn=new SqlConnection(conntr);
SqlCommand comm=new SqlCommand(SQL,conn);
conn.Open();
SqlDataReader dr=comm.ExecuteReader();

dr.Read();

　　　　　　　　　ar.Add(dr["Polls_Option1"].ToString()); 　　　　　ar.Add(dr["Polls_Option2"].ToString()); 　　　　　ar.Add(dr["Polls_Option3"].ToString()); 　　　　　ar.Add(dr["Polls_Option4"].ToString());
ar.Add(dr["Polls_Option5"].ToString());

conn.Close();
return ar;
}


问我怎么能够绑定RadioButtonList的DataValueField属性呢？
因为那样一份调查问卷才可以进行统计！

至于要实现的功能，就象csdn的调查问卷一样！大虾门，救命啊！

比较难的问题啊：）
你用SortList看看？

don't quite understand your question, if you use

<asp:RadioButtonList DataSource='<%# .. %>'

the value and text will be bound to the value from the arraylist, for example

<form runat="server">
<asp:RadioButtonList id="rbl" runat='server' />>
<asp:Button text="submit" runat=server OnClick="GetSel" />
</form>

<script language="C#" runat="server">
void Page_Load(Object sender, EventArgs e)
{
if (!IsPostBack)
{
ArrayList al = new ArrayList();
for (int i=0; i < 10; i++)
al.Add(i);

rbl.DataSource = al;
rbl.DataBind();
}
}

void GetSel(Object sender, EventArgs e)
{
ListItem li = rbl.SelectedItem;

Response.Write(String.Format("selected index:{0}<BR> text:{1}<BR>value:{2}<BR>", rbl.SelectedIndex, li.Text,li.Value));
}
</script>

in your case, you just need to do

foreach(DataListItem dli in question.Items)
{
RadioButtonList rbl = (RadioButtonList)dli.FindControl("RadioButtonList1");
ListItem li = rbl.SelectedItem;

Response.Write(String.Format("selected index:{0}<BR> text:{1}<BR>value:{2}<BR>", rbl.SelectedIndex, li.Text,li.Value));
}
