asp.net Dropdown Disable Issue
<p>I have a ASP.Net webpage with following <strong>edit</strong> rules</p>

<ol>
<li>Normal user can edit only blank fields</li>
<li>Admin user can edit all fields ( No Issue!!)</li>
</ol>

<p>To accomplish this, I tried to "<strong>Disable</strong>" all fields which have a value using javascipt, 
but on postback all the disabled fiels lost its state . So I change to <strong>Readonly=true</strong> . Now all textboxes are working as expected. But the Dropdowns can still editable even though the readonly is true . </p>

<p>How can i accomplish this without losing the control`s value on postback ?</p>

<p>Thanks in advance . </p>
