To connect DialogContentID with content of dialog (html elements in aspx), an application should process
<ClientSideEvents Initialize="WebHtmlEditor1_Initialize" /> event.
Codes below should appear within the HEAD section of HTML.

<script type="text/javascript"><!--

// That function is called when WebHtmlEditor1 was initialized.
function WebHtmlEditor1_Initialize(oEditor)
