i was trying this  little bit of code...

<< page_load....>>
                  if(!Page.IsPostBack)
                  {
                        ArrayList Person = new ArrayList();
                  
                        Person.Add(new Person("sree",23));
                        Person.Add(new Person("sreekumar",231));

                        Repeater1.DataSource=Person;
                        Repeater1.DataBind();
                  }
            }

              public ArrayList  getSex(string name)
        {
                  ArrayList Personsex = new ArrayList();
                  
                  Personsex.Add(new Personsex(name,"Male",1));
                  Personsex.Add(new Personsex(name,"Female",2));
                  return Personsex;
         }
      }
more code here...
----------
      class Person
      {
            string _name;
            int _id;
            
            public string name
            {
                  get
                  {
                        return _name;
                  }
                  set
                  {
                        _name=value;
                  }

            }
            public int id
            {
                  get
                  {
                        return _id;
                  }
                  set
                  {
                        _id=value;
                  }

            }

            public Person(string name,int id)
            {
                   _name=name;
                   _id=id;
            }
      }

-----

      class Personsex
      {
            string _myname;
            string _sex;
            int _age;
            public string name
            {
                  get
                  {
                        return _myname;
                  }
                  set
                  {
                        _myname=value;
                  }

            }
            
            public string sex
            {
                  get
                  {
                        return _sex;
                  }
                  set
                  {
                        _sex=value;
                  }

            }
            public int age
            {
                  get
                  {
                        return _age;
                  }
                  set
                  {
                        _age=value;
                  }

            }

            public Personsex(string myname,string sex,int age)
            {
                  _myname=myname;
                  _sex=sex;
                  _age=age;
            }
      }
--------------------------------


What I am trying to achieve is display list of names and list of sex against them. even though this is not a real life requirement I am trying to simplify things here to explain my problem.  somthing
like

name1   male O   female O
name2   male O   female O
name3   male O   female O
name4   male O   female O

0->radio button

now for the partial aspx code...

<form id="Form1" method="post" runat="server">
<asp:Repeater id="Repeater1" runat="server">
<ItemTemplate>
<%#DataBinder.Eval(Container.DataItem, "name") %>
<br />
<asp:RadioButtonList id="radiolist1" runat="server"  
DataSource='<%#getSex((string)DataBinder.Eval(Container.DataItem,"name"))%>'
DataTextField="sex"
DataValueField="name"
>                                                                     
</asp:RadioButtonList>
</ItemTemplate>
</asp:Repeater>
<asp:Button text="Submit" runat="server" ID="Button1" />
<p>
<asp:Label id="Label1" runat="server" /></p>
</form>


I want to pass the name from the repeater1 to the radiobuttons and put in DataValueField field, or else how will i identify the options??? now when iam using age as value it works ,when i change it to name ,doesnt work as expected... is this the right way??? or any better way to achieve this???

Number and values of  radio buttons are dynamic . In actual I would be getting the values from database and storing the selected option back..

I figured out the problem here... I had multiple items with the same value in the datavaluefield property.    When a user clicked a choice, it grabbed the first option in the list.  I changed the datavaluefield to a unique ID and all is well.  I thought that multiple list items could have the same value...

anyways thanks for the replies...
