First, we need to get all the files ready:

Open Admin.aspx file and add TinyMCE to page:

<!-- TinyMCE -->
    <script type="text/javascript" src="Editors/TinyMCE/tiny_mce.js"></script>
    <script type="text/javascript">
        tinyMCE.init({
            // General options
            mode: "textareas",
            theme: "advanced",
            plugins: "spellchecker,pagebreak,style,layer,table,save,advhr,advimage,advlink,emotions,iespell,inlinepopups,insertdatetime,preview,media,searchreplace,print,contextmenu,paste,directionality,fullscreen,noneditable,visualchars,nonbreaking,xhtmlxtras,template",
 
            // Theme options
            theme_advanced_buttons1: "save,newdocument,|,bold,italic,underline,strikethrough,|,justifyleft,justifycenter,justifyright,justifyfull,|,styleselect,formatselect,fontselect,fontsizeselect",
            theme_advanced_buttons2: "cut,copy,paste,pastetext,pasteword,|,search,replace,|,bullist,numlist,|,outdent,indent,blockquote,|,undo,redo,|,link,unlink,anchor,image,cleanup,help,code,|,insertdate,inserttime,preview,|,forecolor,backcolor",
            theme_advanced_buttons3: "tablecontrols,|,hr,removeformat,visualaid,|,sub,sup,|,charmap,emotions,iespell,media,advhr,|,print,|,ltr,rtl,|,fullscreen",
            theme_advanced_buttons4: "insertlayer,moveforward,movebackward,absolute,|,styleprops,spellchecker,|,cite,abbr,acronym,del,ins,attribs,|,visualchars,nonbreaking,template,blockquote,pagebreak,|,insertfile,insertimage",
            theme_advanced_toolbar_location: "top",
            theme_advanced_toolbar_align: "left",
            theme_advanced_statusbar_location: "bottom",
            theme_advanced_resizing: true,
 
            // Skin options
            skin: "o2k7",
            skin_variant: "silver",
 
            // Example content CSS (should be your site CSS)
            content_css: "css/example.css",
 
            // Drop lists for link/image/media/template dialogs
            template_external_list_url: "js/template_list.js",
            external_link_list_url: "js/link_list.js",
            external_image_list_url: "js/image_list.js",
            media_external_list_url: "js/media_list.js",
 
            // Replace values for the template plugin
            template_replace_values: {
                username: "Some User",
                staffid: "991234"
            }
        });
    </script>
    <!-- /TinyMCE -->

Add a ASP.NET TextBox control to the page, so that the TinyMCE will hook to this TextBox. then add a Button and Label. button is used to save the content. label used to display the status info:

    <p>
        <asp:TextBox ID="textBox1" runat="server" 
                     Height="300px" Width="100%" 
                     TextMode="MultiLine">
     
        </asp:TextBox>
    </p>
    <asp:Button ID="saveBtn" runat="server" Text="Save" onclick="saveBtn_Click" />
    <asp:Label ID="statusLabel" runat="server"></asp:Label>

Add button event in the behind code file:

    protected void saveBtn_Click(object sender, EventArgs e) {
        string path = Server.MapPath("test.txt");
        using (var writer = new StreamWriter(path)) {
            writer.WriteLine(textBox1.Text.Trim());
        }
        statusLabel.Text = "Saved";
    }

All things done:

Simple mode:

    <script type="text/javascript" src="Editors/TinyMCE/tiny_mce.js"></script>
    <script type="text/javascript">
        tinyMCE.init({
            // General options
            mode: "textareas",
            theme: "simple"
        });
    </script>
