         This ModalPopup will be spawned programmatically. The ModalPopupExtender that this popup is attached to
            has a hidden TargetControl. The popup can be <asp:LinkButton runat="server" ID="showModalPopupServerOperatorButton" Text="shown via server in code behind" OnClick="showModalPopupServerOperatorButton_Click" /> and 
            <a id="showModalPopupClientButton" href="#">on the client in script</a> by calling the ModalPopupExtender methods to show and hide.<br />

                You can now use this sample to see how to use ModalPopup with an invisible TargetControl. The ModalPopupExtender
                this popup is attached to has a hidden target control. The popup is hidden 
                <asp:LinkButton runat="server" ID="hideModalPopupViaServer" Text="on the server side in code behind" OnClick="hideModalPopupViaServer_Click" /> and

        <p>
            The ModalPopup extender allows a page to display content to the user in a "modal"
            manner which prevents the user from interacting with the rest of the page. The modal
            content can be any hierarchy of controls and is displayed above a background that
            can have a custom style applied to it. When displayed, only the modal content can
            be interacted with; clicking on the rest of the page does nothing. When the user
            is done interacting with the modal content, a click of an OK/Cancel control dismisses
            the modal content and optionally runs custom script. The custom script will typically
            be used to apply whatever changes were made while the modal mode was active. If
            a postback is required, simply allow the OK/Cancel control to postback and the page
            to re-render. You can also absolutely position a modal popup by setting the X and Y 
            properties. By default it is centered on the page, however if just X or Y is specified
            then it is centered vertically or horizontally.
