Radio Button Check Changed even not firing
<p>I've 2 radio buttons in a user control and control is registered to the page. When i click on the radio button, the event(CheckChanged) is not firing. </p>

<pre><code>&lt;asp:View ID="viewfirst" runat="server"&gt;
                    &lt;asp:UpdatePanel ID="updatepanel1" runat="server" UpdateMode="Always"&gt;
                        &lt;ContentTemplate&gt;

                            &lt;asp:RadioButton ID="radio1" Text="Yes" Enabled="true" runat="server" /&gt;
                            &lt;asp:RadioButton ID="radio2" Text="No" Enabled="true" runat="server" /&gt;
                        &lt;/ContentTemplate&gt;
                    &lt;/asp:UpdatePanel&gt;
                &lt;/asp:View&gt;

Below is code in behind file of the control. 


 Protected Sub radio1_CheckedChanged(sender As Object, e As EventArgs) Handles radio1.CheckedChanged
    //
    //
End Sub
</code></pre>

<p>It seems everything looks good, but something is wrong. Can you please let me know.</p>
