Web Forms :: Display Server Side Yes No Confirmation Box On DropDownList Change

I was wondering if there is a way to capture the yes/no values on the server side once the y/n buttons are clicked on a javascript pop up?

I am displaying the y/n pop up while using a dropdown menu but pretty much all the solutions i have seen so far use button's onClick event.

By reading article: [URL]

I am able to see the pop up box with the yes/no options but after i click a 'yes' or 'no', i don't see  'You clicked Yes' or 'You clicked No'.

This is the code i have so far which has been taken from Muddassar's article that uses a button, not a drop down.

I can see for button the "Confirm()" is being called by OnClientClick event, but i haven't been able to make it to work in a dropdown.

On the aspx page:

<asp:DropDownList ID="ddlWorkBucket" runat="server" AutoPostBack="true" DataSourceID="SqlDataSource8" DataTextField="workBucketName" DataValueField="workBucketID" Width="120px" onChange="Confirm()" OnSelectedIndexChanged="OnConfirm"></asp:DropDownList>

Also on the same aspx page is this javascript function:

 <script language ="javascript" type="text/javascript"> 
function Confirm() {    var confirm_value = document.createElement("INPUT");   
confirm_value.type = "hidden";    confirm_value.name = "confirm_value";
