or set autopostback = true, then on selected index change save your ddl value to session or write it to your db.

Sesion("MyDDLValue") = Me.MyDDL.SelectedValue

Is there any way to get the value in the code behind without bringing the java script to picture.

Basically i select something and then disable it. Then i want to get the selectedtext.

use the selected index changed event of the ddl and set autopostback=true.  Which is javascript by the way the IDE just does it for you;)

thats a lot of postbacks its kind of a judgement call, I'd use this javascript routine instead, but thats enitrely up to you.

 <html>
<head>
    <title>Disable Controls Example</title>
    <script language="JavaScript" type="text/javascript">
    function List1_Changed()
    {
        var selectedValue = document.form1.List1[document.form1.List1.selectedIndex].value;
        if (selectedValue == 2)
        {
            // Disable controls
            document.form1.txtTest.disabled = true;
        }
        else
        {
            // Enable controls    
            document.form1.txtTest.disabled = false;
        }
    }
    </script>
</head>
<body>
<form name="form1" method="post" action="">
  <select name="List1" onChange="List1_Changed();">
    <option value="1">1</option>
    <option value="2">2</option>
  </select>
    <input name="txtTest" type="text" id="txtTest">
</form>
</body>
