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

Because your button is in control it could be that there is a validation from another control that don t allow the button to submit  The result in my case was to add CausesValidation property to the button     lt asp Button ID  btn QuaSave  runat  server  Text  SAVE  OnClick  btn QuaSave Click  CausesValidation  False   gt

In the case of nesting the LinkButton within a Repeater you must using something similar to the following    lt asp LinkButton ID  LinkButton1  runat  server  CommandName  MyUpdate  gt LinkButton lt  asp LinkButton gt    protected void Repeater1 OnItemCommand object source  RepeaterCommandEventArgs e         if  e CommandName Equals  MyUpdate                     some code

Have you copied this method from other page application   if yes then it will not work  So you need to delete the event and event name assigned to the button then go to design and go to button even properties go to onClick event double click next to it  it will generate event and it automatically assigns event name to the button  this should work

Add validation groups for your validator elements  This allows you distinguish between different groups which to include in validation  Add validation group also to your submit button
