Read Only asp drop down list

I'm working on an ASP.Net app

I have a drop down that, under some conditions, should be 'read only', that is, the user can't change it but, on a post back its selected value can be read.

Now I know that the readOnly attribute is not available for drop downs so I'm trying to build a method that simulates this

so I wanted to make a javascript function that doesnt let the user 'open' the drop down to select an item. is this possible?

here's the example

function MakeDropDownReadOnly(dropDownId, makeReadOnly){

    var myDropDown = document.getElementById(dropDownId);

    if(makeReadOnly){
        //Block drop down

    }
     else{
          //Unblock drop down
     }
}

tks

onfocus="this.blur()" might work to prevent a user to interact with the select.

Have You tried "Enabled" property of the DropDownList?

Make it disabled then in form submit (using JavaScript) enable it again so the value will be sent to the server.

Sample code to enable upon submitting:

document.getElementById("<%=DropDown1.ClientID%>").disabled = false;

Can't you use Enabled="false"?
