Exception Details: System.Web.HttpException: The state information is invalid for this page and might be corrupted
--------------------------------------------
This the error code we may use sometime: This button is only calling a JS so we do not need a server-side <asp:Button>.
<asp:Button ID="printButton" runat="server" Text="Print" OnClientClick="javascript:print_div('ctl00_ContentPlaceHolder1_div_i_coupon_local_list');" />
This is the correct code we should use to avoid the view state error: We should use client-side button.
<input type="button" value="Print" onclick="javascript:print_div('ctl00_ContentPlaceHolder1_div_i_coupon_local_list');" />
