When it back,the navBar still hiding,how can I show the navBar recover on [more] screen?(I need the EDIT button in [more])

Answer: 
You should use [Html Agility Pack](http://htmlagilitypack.codeplex.com/) to work with html.

```
string text = @"<div><span class=""help"">This is text.</span>Hello, this is text.      </div>
                <div>I have a question.<span class=""help"">Hi</span></div>";
HtmlDocument doc = new HtmlDocument();
doc.LoadHtml(text);
var nodes = doc.DocumentNode.SelectNodes("//span[@class='help']");
foreach( HtmlNode node in nodes)
{
   node.Remove();
} 
String result = doc.DocumentNode.InnerHtml;

```
get the elements to contain the runat="server" so they can be accessed from the codebehind and then when it is suitable try getting the element by its id name and do either 
element.innerHTML = ""; or element.innerText = "";
