Bind HTML Editor to Data
You can use the ASPxHtmlEditor.Html property to bind ASPxHtmlEditor content to datasource fields. This technique is useful if you integrate the editor into the ASPxGridView or asp:Repeater.
<dx:ASPxGridView ID="ASPxGridView1" runat="server">
<Templates>
<EditForm>
<dx:ASPxHtmlEditor ID="ASPxHtmlEditor1" runat="server"
Html='<%# Eval("DescriptionHtml") %>'>
</dx:ASPxHtmlEditor>
...
</EditForm>
</Templates>
</dx:ASPxGridView>
