If you are using updatepanel on onclick event, this may happen.

Use 'EnableEventValidation="false"' in your page markup like this :

<%@ Page Language="C#" MasterPageFile="~/ars_home.master" AutoEventWireup="true" CodeFile="Transaction_Window.aspx.cs" Inherits="Transaction_Window" EnableEventValidation="false" %>

Hope this helps
