    text
    copied!<p>I have made a web page to display a graphic and then allow the user to enter some comments underneath it. The user is prompted for input and I am trying to store each comment in a List and then display the list as an ordered HTML list. Here is the relevant code:</p> <pre><code>&lt;script runat="server"&gt; private List&lt;string&gt; messages = new List&lt;string&gt;(); protected void Button2_Click(object sender, EventArgs e) { messages.Add(TextBox2.Text); TextBox2.Text = ""; } protected void Button3_Click(object sender, EventArgs e) { messages.Clear(); } protected void Button4_Click(object sender, EventArgs e) { string output = "&lt;ol&gt;"; foreach (string message in messages) { output += "&lt;li&gt;"; output += message; output += "&lt;/li&gt;"; } output += "&lt;/ol&gt;"; Message.InnerHtml = Server.HtmlEncode(output); } protected void Chart1_Load(object sender, EventArgs e) { } &lt;/script&gt; &lt;html xmlns="http://www.w3.org/1999/xhtml"&gt; &lt;head runat="server"&gt; &lt;title&gt;&lt;/title&gt; &lt;/head&gt; &lt;body&gt; &lt;form id="form1" runat="server"&gt; &lt;div&gt; Key Messages:&lt;br /&gt; &lt;span id="Message" runat="server"&gt; &lt;asp:TextBox runat="server" ID="TextBox2" Width="500px"&gt;&lt;/asp:TextBox&gt; &lt;asp:Button runat="server" ID="Button2" Text="Enter Message" Onclick="Button2_Click" /&gt; &lt;asp:Button runat="server" ID="Button3" Text="Clear Messages" onclick="Button3_Click" /&gt; &lt;asp:Button runat="server" ID="Button4" Text="Done" onclick="Button4_Click" /&gt; &lt;/span&gt; &lt;/div&gt; &lt;/form&gt; &lt;/body&gt; &lt;/html&gt; </code></pre> <p>The output from this is:</p> <pre><code>Key Messages: &lt;ol&gt;&lt;/ol&gt; </code></pre> <p>So I have two mysteries:</p> <p>1) Why isn't the text being entered into the textbox being added to the list</p> <p>2) Why is the new HTML being displayed as plain text.</p> <p>Any advice is appreciated.</p> <p>Regards.</p>
