This is something you feel not related to your question. But generally Enable/Disable works well for windows application. For asp.net it may not be actually disabled for a hacker. A simple injection of javascript enable the button. So any sensitive branching should not be by the way of simple branching by the UI controls. You need to have a validation at your server side code. Some of the prevention settings you may have is the ValidateRequest attribute at the page tag. For more information refer this

i think this can be done in much simpler manner without Postback
see here is the demo
Page 1:Disable.htm

XML

<html>
<head>
<title></title>
<script>
    function Disable(controleid) {
        document.getElementById(controleid.id).disabled = true;
        window.open("Enable.htm");
    }
</script>
</head>
<body >
<input type="button" id="one" onclick="Disable(this)" />
</body>
</html>

Page 2:Enable.htm

XML

<html>
<head>
<title></title>
<script>
    function Enabled() {
        window.top.opener.document.getElementById('one').disabled = false;
    }
</script>
</head>
<body >
<input type="button" id="two" onclick="Enabled()" />
</body>
</html>

In order to disable the button on the second page from the the first page follow the steps as below

1. Declare the session Variable on the first page and then redirect to the Secondpage.aspx
Session["L"] = "0"; // variable declaration
then write response.redirect ("secondPage.apsx") // redirect to the second page

2. Go to the second Page and enter the code on the Page Load section

if (Session["L"].ToString()=="0")
{

myButton.Enabled = false;

}

Solution 1

Whats stopping you? All sounds straight and simple.

You have various ways to access the 1st page from 2nd, for example:
1. Querystring (if navigating)
2. PreviousPage concept (if not navigating)

All you need is to pass on the flag to one page from other. Did you try at all?
Please do so and do post specific issue, if you face.

Solution 2

u can pass querystring from second page to first page

on second page button click u can write
response.redirect(firstpage.aspx?id=1);

then on first page load u can do
if(Convert.Tostring(Request.Querystring["id"])=="1")
button.Enabled=true;
