RichEditControlActions.cs

static void buttonCustomAction_ItemClick_Html(object sender, ItemClickEventArgs e) {
    RichEditControl richEdit = e.Item.Tag as RichEditControl;
    richEdit.LoadDocument("Documents\\Grimm.docx");
    //Export document to the file:
    richEdit.SaveDocument("resultingDocument.html", DocumentFormat.Html);
    //Export document to the stream:
    using (FileStream htmlFileStream = new FileStream("Document_HTML.html", FileMode.Create)) {
        richEdit.SaveDocument(htmlFileStream, DocumentFormat.Html);
    }

    System.Diagnostics.Process.Start("resultingDocument.html");
}

RichEditControlActions.vb

Shared Sub buttonCustomAction_ItemClick_Html(ByVal sender As Object, ByVal e As ItemClickEventArgs)
    Dim richEdit As RichEditControl = TryCast(e.Item.Tag, RichEditControl)
    richEdit.LoadDocument("Documents\Grimm.docx")
    'Export document to the file:
    richEdit.SaveDocument("resultingDocument.html", DocumentFormat.Html)
    'Export document to the stream:
    Using htmlFileStream As New IO.FileStream("Document_HTML.html", IO.FileMode.Create)
        richEdit.SaveDocument(htmlFileStream, DocumentFormat.Html)
    End Using

    System.Diagnostics.Process.Start("resultingDocument.html")
