Radio Button OnCheckedChanged() event is not called

[anada8886]

Hello everyone, I have a gridview,in which each row populates a question with its answers(as radio buttons). I have to execute some code on radio button's OnCheckedChanged event.Somehow,on its OnCheckedChanged event,page is postbacked but it is not going to OnCheckedChanged() method.Can anyone give any suggestions for how can I achieve this? The code looks somewhat like this :

<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<asp:GridView ID="GridView1" OnRowDataBound="GridView1_OnRowDataBound" AutoGenerateColumns="false"
runat="server">
<Columns>
asp:TemplateField
<ItemTemplate>
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:GridView ID="GridView2" AutoGenerateColumns="false" runat="server">
<Columns>
asp:TemplateField
<ItemTemplate>
<asp:RadioButton ID="RadioButton2" runat="server" AutoPostBack="true" OnCheckedChanged="RadioButton2_CheckedChanged" />

                                        </ItemTemplate>
                                    </asp:TemplateField>
                                </Columns>
                            </asp:GridView>
                        </ContentTemplate>
                    </asp:UpdatePanel>
                </ItemTemplate>
            </asp:TemplateField>              
        </Columns>
    </asp:GridView>

Clean Solution and then Rebuild.

Thanx for your reply,but I have already tried doing this. In fact,I created a separate project just to check whether it works or not,but it still failed. The same method I called on a button's OnClick & it worked but it didn't work for RadioButton's OnCheckedChanged().

Since you have defined the control inside grid u have to create the checked event, ex- <asp:GridView ID="grdSearch" runat="server" Width="100%">                                           <Columns>                                                 <asp:TemplateField HeaderText="FirstName">                                                       <ItemTemplate>                                                             <asp:LinkButton ID="lbtnFName" runat="server" Text='<%# eval("fname") %>' />                                                       </ItemTemplate>                                                 </asp:TemplateField>                                           </Columns>                                     </asp:GridView> Code behind- Protected Sub grdSearch_RowCreated(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles grdSearch.RowCreated                      Dim LinkButton1 As LinkButton             Select Case e.Row.RowType                   Case DataControlRow
