    <asp:RadioButton ID="Rad1" runat="server" Text="RadControl1" AutoPostBack="true" OnCheckedChanged="Rad1_CheckedChanged" />
    <asp:RadioButton ID="Rad2" runat="server" Text="RadControl2" AutoPostBack="true" OnCheckedChanged="Rad2_CheckedChanged" />

    <asp:ListBox ID="lst1" runat="server" >


    <asp:ListBox ID="lst2" runat="server">


    Server Side

    protected void Rad1_CheckedChanged(object sender, EventArgs e)

    What you have tried so far?

    as you said when you click on radiobutton you want to show the textbox value in to particular listbox.

    So, you need to wrote code under checkedchanged event of radiobutton and add the textbox value into listbox item.

    Already In response 1, they provide some sample for the same refer that if you still having any queries let us know.

    1. You can do this using simple javascript/Jquery.
    Following is for single check box ,list box ... Alter the code based on your requriement

    <asp:ListBox ID="ListBox1" runat="server" Width="150" Height="60"></asp:ListBox>
    <br />
    <hr />
    <asp:TextBox ID="txtValue" runat="server" />
    <input type="checkbox" name="chk1" id="chk1" value="CheckBox1">
    <asp:Button ID="btnAdd" Text="Add" runat="server" OnClientClick="return AddValues()" />

    2. Implement the logic in your javascript

    <script type="text/javascript">
    function AddValues() {
    // Implement your validation (Which check box was checked based on the selection you can add the value
    var txtValue = document.getElementById("<%=txtValue.ClientID %>");
    var listBox = document.getElementById("<%= ListBox1.ClientID%>");
    var option = document.createElement("OPTION");
    option.innerHTML = txtValue.value;
    option.value = txtValue.value;
    txtValue.value = "";
    return false;

    it is like a small assignment, you can use javascript or server side code for it
    lets see how javascript will help you
    <script language="Javascript">
    function setValues()
    //check if radio button 1 is selected
    if (document.getElementById("rb1").checked)
    var v = document.form1.txtValue.value;
    // get the TextBox Value and assign it into the variable
    AddOpt = new Option(v, v);
    document.form1.listbox1.options[i++] = AddOpt;
    var v = document.form1.txtValue.value;
    // get the TextBox Value and assign it into the variable
    AddOpt = new Option(v, v);
    document.form1.listbox2.options[i++] = AddOpt;


    hope it helps
