Hi,

Please have a look into the sample code snippet which works fine at my end.

Master Page ASPX:

<telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" runat="server" Skin="Default">

</telerik:RadAjaxLoadingPanel>

<telerik:RadAjaxPanel LoadingPanelID="RadAjaxLoadingPanel1" runat="server" ID="RadAjaxPanel1">

<asp:Panel ID="Panel1" runat="server" Height="100" Width="100" Style="border: 1px solid red;">

</asp:Panel>

<asp:Button ID="Button1" runat="server" Text="Update" OnClick="Button1_Click" />

</telerik:RadAjaxPanel>

Master Page C#:

protected void Button1_Click(object sender, EventArgs e)

{

Response.Redirect("~/RadAjax/AjaxifyRadioButton.aspx");

}

Thanks,
Shinu.
