You have got to realize that 'disabled' doesn't mean or equate to 'readonly'. Both these properties disallow the user from editing the entered text but the real difference comes when you try retrieving the form element values at the server. If the element is marked with the property 'disabled', the form element value won't be submitted to the server while a form elements' value marked 'readonly' will be.

<input type="text" name="txtName" id="txtName" readonly="readonly" />
<input type="text" name="txtName" id="txtName" disabled="disabled" />
