Hi experts,
I have a three cascading dropdowns for Coutry,State and City.
This works very well.
What I am trying to do is,
When 'Admin' is viewing a records of the user,those dropdowns shows values entered previously(That's done)
When normal user is viewing this form,I want to show data in readonly form,I tried to disable the dropdowns
 but it is not working.Those dropdowns should be disabled but should have value from database.

These dropdowns get data from web service.

Your help is really appreciated.
Thanks

Make Dropdowns readonly for normal users. Here is how...

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
"http://www.w3.org/TR/html4/strict.dtd">
<HTML lang="en">
<HEAD>
<TITLE>HTML</title>
<META http-equiv="Content-Type" content="text/html; charset=utf-8">
<STYLE type="text/css">
<!--
.greyed {
color: #999999;
}
-->
</STYLE>
<SCRIPT language=JavaScript type=text/javascript>
<!--
function freezeList(whichList){
var chosen=whichList.options.selectedIndex;
whichList.onchange=function(){
whichList.options.selectedIndex=chosen;
}
whichList.className="greyed";
}
//-->
</SCRIPT>
</HEAD>
<BODY>

<FORM name="myForm">
<DIV>
<SELECT name="readList" readonly>
<OPTION>Red</OPTION>
<OPTION>Green</OPTION>
<OPTION>Blue</OPTION>
<OPTION>Yellow</OPTION>
</SELECT>
<INPUT type="button" value="Freeze The List" onclick="freezeList(this.form.readList)">
</DIV>
</FORM>

</BODY>
</HTML>

You can use dropdown variable object name
ddlTest.Enabled = false;

By definition, a dropdown is always READONLY.
By definition, a dropdown DISABLED is not sent via FORM SUBMIT.

If you are allowing multiple then you use below technique
----------------------------------------------------------------------------------------
<FORM name="myForm" method="post">
 <SELECT name="readList[]" multiple readonly onmouseover="freezeList(this.form.elements['readList[]'])">
 <OPTION value="Red">Red</OPTION>
 <OPTION value="Green" selected>Green</OPTION>
 <OPTION value="Blue">Blue</OPTION>
 <OPTION value="Yellow" selected>Yellow</OPTION>
 </SELECT>
 <INPUT type="submit" value="SUBMIT">
 <input type="button" value="freeze" />
 </FORM>

Hope this helps!!!
