Server-side Navigation Menu Based On Html Contents?

Jul 9, 2010

I need to do some styling to a bunch of webforms, containing articles formatted in a rather uniform way. I can change any source code I want.

What I need is a quick way to dynamically create a navigation menu (on the server side) for an ASP.NET webform, based on contents of a specified div.

For example, given the following HTML:

<div id="article">
<h2 id="first">Chapter 1</h2>
<p>Some text...</p>
<h2 id="second">Chapter 2</h2>
<p>Some other text</p>
</div>

I would like to insert something like this at the end (and render it at the server side, not in a script):

<div id="navigation">
<ul>
<li><a href="#first">Chapter 1</a></li>
<li><a href="#second">Chapter 2</a></li>
</ul>
</div>

NOTE: I know I could iterate through parent div's child controls in codebehind (although I would need to make them all "run at server", or even parse the InnerHtml property of the parent div), but if feels pretty weird.

Also, I am aware that if the article was being created from a data source, I would have the content already organized, but I would like to make as little changes needed in the existing pages.

MVC :: Displaying Contents To Right Side Of Left Navigation Bar

Mar 21, 2011

My master page is left navigation bar. It displays correctly on my aspx pages, but the other content of the aspx page is displayed right underneath the master page content. I don't want anything to be displayed under the left navigation bar. I want the other stuff to be displayed on the right side of the navigation bar. Is their any way I can do that. below is my code

<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/NavigationMenu.Master" Inherits="System.Web.Mvc.ViewPage<dynamic>" %>
<%@ Import Namespace="CIS_NG.Models.Menu" %>
<asp:Content ID="Content1" ContentPlaceHolderID="titleContent" runat="server">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server" >
<h2>Welcome to CS page</h2>
</div>
</asp:Content>

i want the "welcome to Cs page" displayed right next to my left navigation bar that is coming from my master page. I can do this to avoid it

<div style="text-align: center;"><h2>Welcome to CS-NG</h2>

but I thought if I write somthing in the content page, it will automatically come to right side of the page.

Can An Iframe Load Its Contents At The Server Side Rather Than Client Side

Dec 21, 2010

I know that setting runat="server" and specifying an id for an iframe control, makes it accessible on the server side but what I need is that the iframe source contents get loaded at server side not client side.Is it possible?Why do I need it this way?

Currently my iframe source site is configured for ntlm authentication and sso which means it would read my windows credentials whereas I'd need it reads the credentials provided by the site which hosts that iframe.

Filter A Grid At Server Side Based On The Value Typed In A Textbox?

Aug 13, 2010

I want to filter a grid at server side based on the value typed in a text box. And the filter should happen as the user types in text box. Since there is no server side event like keypress on a textbox, I decided to do use the client side onkeypress event and call a server side code using PageMethod. But then ran out with the limitation of PageMethod being static and I can't access grid from server side code.
