You are missing OnSelectedIndexChanged="radiobutton_selectchanged" in the radio button

ASP.NET

<asp:radiobuttonlist id="rdbRemarks" runat="server" AutoPostBack="True" repeatdirection="Horizontal" OnSelectedIndexChanged="radiobutton_selectchanged ">
    <asp:listitem value="F1">Accept</asp:listitem>
    <asp:listitem value="F1">Objection Clear</asp:listitem>
    <asp:listitem value="F4">Objection</asp:listitem>
    <asp:listitem value="R">Reject</asp:listitem>
</asp:radiobuttonlist>

also the code behind must have this handler defined

C#

protected void radiobutton_selectchanged(object sender, EventArgs e)
    {

    }
