Hi allangaunt,
Editor.EnableStripIframeTags Property
Specifies whether to remove inject Iframe tags before writing the string into the db. When this property is set to true (the default) Cute Editor strips all iframe tags from the html to prevent iframe injection attack.
Please set EnableStripIframeTags to false, like below.
<CE:Editor ID="editor1" runat="server" EnableStripIframeTags="false">
</CE:Editor>
Regards,
ken
