Exception message: Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.

lets say i have a aspx page and i got your Error , at first it will look like this 

<%@ Page Language="C#" AutoEventWireup="true"  CodeFile="Default.aspx.cs" Inherits="_Default" %>



<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">



<html xmlns="http://www.w3.org/1999/xhtml">

<head runat="server">

    <title></title>

</head>

<body>

    <form id="form1" runat="server">

    <div>

        <asp:Calendar ID="Calendar1" runat="server"></asp:Calendar>

    </div>

    </form>

</body>

</html>


but to Resolve the issue you need to add it at the top look at the bolded part at the top of the page 

<%@ Page Language="C#" AutoEventWireup="true" EnableEventValidation ="false"   CodeFile="Default.aspx.cs" Inherits="_Default" %>



<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">



<html xmlns="http://www.w3.org/1999/xhtml">

<head runat="server">

    <title></title>

</head>

<body>

    <form id="form1" runat="server">

    <div>

        <asp:Calendar ID="Calendar1" runat="server"></asp:Calendar>

    </div>

    </form>

</body>

</html>

Thanks again for the reply..

But in my code we are calling C# code , if i disable this (EnableEventValidation ="false" ) then i wont get any events fired to event log right ?

But i need to fix the solution, but i see we are stepping out of the exception instead resolving.


Could you please let me know, why actually these errors will come up...

Thx,
KVC

NO this will not affect anything in your code. There only Difference is that you will never have the Error you were getting.
