    Hi Prasanth,

    This happens because the ImageButton in the RadRotator item performs a postback and the click event does not bubble to the rotator, thus its server-side event is not raised. You can avoid this by canceling the click event of the image button in order to let the rotator handle it. The following code sample shows how to do this:
    <asp:ImageButton ID="Img1" runat="server" OnClientClick="return false;" ImageUrl='<%# ResolveUrl("Images/" +  XPath("Image")) %>' AlternateText="" style="margin: 0px 11px;" />
