Hey I just began working on a new project that requires, tab navigation, and within each page, more tab navigation, and then within those pages dynamic ASP.NET content. The problem is I do not want all of my code on one page, that would just be a very large and bloated page. I was wondering what available methods of approach there are for this issue. I checked jQuery tabs, and I see I can link html files using AJAX but I need aspx files not just HTML.
Thanks ahead of time.
I've had to deal with this on many projects. After trying quite a few libraries my approach to tabs is to always do these myself using plain CSS.
But note having multiple layers of tabs is a but usability no-no. Remember Windows 3.x and 95 did this quite a bit. It's less an issue these days. You can try an accordion control along with the tabs to filter your screens
One one particular project, we used DevExpress ASPxTabPages for a while. These worked well, but were a bit heavy for such a simple task. We then moved the project to JQuery, but ran into situations where JQuery UI Tabs started to be an issue as well. Particularly when generating tabs using master pages and render actions in ASP.Net MVC. We finally settled on regular CSS and HTML. Javascript really isn't even needed. Though I'm sure JQuery can be used to spruce things up.
An example of CSS tabs can be found at http://www.htmldog.com/articles/tabs/. There are live examples on that page as well.
what you could do is:
make a tab a span
when clicked on that tab/span, fire jquery and do a GET to a page on the server which represents the tab content
pro: no initial loading of the content of the tabs
Con: slight delay when you click a tab (first time only if you can cache the content of the tab)
this is done when you think that only a few of all of your tabs are clicked: you don't have to load all the data users ain't gonna see.
If you think the user is going to look at all the tabs, then you can load everything in one page. You can use a user control for each tab so no super large page and wrap the output of the usercontrol in a DIV
Then also make a tab a span, and when clicked on the tab/span, make the right DIV visible and hide the others.
I just made a user control that contained the Ajax Tab Control for my sub menu. Each tab actually takes you to a different page.
I blogged about how I did this HERE.

I'm creating Views for an ASP.NET MVC application. I'm using _Layout and some other Views like Shop, Contact, etc., which have only one element: "content".
How can I set content change animation? I don't like white flashing while changing.
What you're seeing is unrelated to MVC and is the result of simple HTML page transitions. Since you're actually changing the entire page, the white flashing is the result of loading the new page.
You can manage this through CSS and jQuery. Here is one article that describes one way to manage page transitions. Just search for HTML Page Transitions and you'll see plenty of jQuery libraries made for this with extensive documentation.
Here is one jQuery library I found: Animsition
Some additional information on the white flickering you're seeing from this article.
Amongst the various problems with web page loading, white flicker is
considered to be one of the common issues which occurs during page
access, loading, reloading, and traversing Internet browsers. The
white flicker occurs for various reasons including the browser trying
to render the page before the style sheet has finished loading,
JavaScript issues and other rendering faults. Browsers will always
wait until everything (beyond images) has finished downloading before
rendering.
It depends of your css template, if It has spinners you should look in the documentation, if your template doesn´t have, look for one, there are a lot of template of spinners with documentation.
Here is an example of documentation (of course, this apply if you are using inspinia, but all of them have similar applications):

I have to build a site like France24.com, There is a navigation on the left and two arrows on sides for scrolling to the sides. when you click on the arrows or one of navigation items , the related page (preloads) and appears without refreshing the page. How to do that? Is there any usable framework or sample for this?
Regards
After looking at the website, I see what you are trying to do. I see a way to do this, which is through a simple JQuery method load() ( http://api.jquery.com/load/ ). This behaves like get(), so on clicking the arrow, an event could be triggered where you can load another piece of HTML code in place of the one the user is currently looking at.
If you need dynamic content to load instead of a simple static HTML code, it's possible to achieve that by filling in the dynamic part into the HTML code that you want to load before actually loading it. A library that you can use to achieve something like this is React js, developed by FB. Good luck!
For some reason whenever I go to the page of my website that has the crystal report on it my main navigation bar disappears. Here is what the header for the site (with the navigation menu) is suppose to look like:
and here is what it looks like when there is a report on the page:
Could someone tell me what is causing this and how I can fix it?
I'm using master page for the header by the way.
Greener, the Crystal Report viewer is a dynamic HTML representation of the report. It combines JavaScript, HTML and CSS (duh, what doesn't) to represent your report on the webpage. The toolbars are powered by JavaScript calls to .JS that is linked in when the CrystalReportViewer control is rendered to your page.
My point is, all of this introduces a LOT of stuff that can conflict with your existing page. In particular JavaScript errors can occur (which can cause certain things to stop rendering) OR CSS the report uses happens to apply styles you never intended to have applied to objects in your page.
I highly recommend installing the Web Developer toolbar and/or FireBug to FireFox, IE, or whatever browser they are offered on these days. FireFox's implementation of those is quite good in my experience.
When the page loads you can use the 'CSS' menu of the Web Developer toolbar to actually disable some or ALL the styles applied to the page. If disabling Crystal related styles (or all) makes your missing toolbar appear, then it's probably a conflict in your CSS. A front end developer would know to adjust the styles (i.e. add the !important directive to a style, change class/id names, etc.) to address this.
Alternatively, FireBug may be reporting JavaScript errors (heck, even FireFox can show these in the console) which could indicate a problem that prevents the completion of rendering your toolbar.
An outside possibility is that the report itself contains mark-up. For example, if you had certain fields in the report contain HTML that happened to be rendered by the browser, this could create an open div tag, css styles and even JavaScript that would do all the stuff I explained above.
I hope this narrows it down for you. Happy troubleshooting!
I was having the same issue and after hours of searching I finally resolved it... check this out... http://scn.sap.com/thread/1926659
In the crystalreportviewer css file, I adjusted the div class = clear and changed the height attribute and disabled overflow:hidden. Hopefully, that works for you. Good luck!
I found the solution after searching on the web and is a quite simple.
On the Site Master, change the Name for all the places you have the style "clear" for example "clear1" and change it too en the site.css with that name.
The problem is for the conflic with the namespaces with Crystal Report css.
Hope this help.
i want to make a css/jquery tabbed for an "Admin panel", so it will all be loaded without the need to refresh.
im going to do it dynamicly but its a small exercise site so i know ill have only 3-4 main "areas" to edit in the panel (the tabs in the top).
the thing is i have other links for each editing area.
is there a way to do it with jquery, without the need of putting all the code in 1 page, in 3-4 divs and make them all invisble except the tabed being choosen(like ive seen in examples)?
in examples i saw all the content in one page, and if adding the top tabs and also the pages of each area(lets say delete, edit etc) its alot of code.
is there a comfortable way of doing it, while being able to make it dynamicly in the future?
edit to answers:
i already made tab from the this tutorial:
http://net.tutsplus.com/html-css-techniques/how-to-create-a-slick-tabbed-content-area/
the thing is, at first in the admin menu i have like 13-14 html pages(before it becomes php) with different operations.
how would you take 13 pieces of code(they have the layout and the admin+admin menu yet the content is changed) that should be in different files, and make them show up in the same tab?
would you have to split each code to only its div, and then load it someway?
from the tutorial above, they used all of the content in one page and used invisible......
how would you load 13 pieces?
Have a look at the jQuery UI Tab Widget:
you can load the tab content statically or dynamically with AJAX
it uses the jQuery CSS framework
it's easy and full of sample code
I have one web page in ASP.NET and I want that page to be disabled until the whole page loading process gets completed.
One way is to activate a lightbox without content that will dim the whole page and then on the body onload event hide that lightbox.
Lightbox is a like having a modal window above the original window, and is used to preview pictures and other content. It could easy be modified to do what you want. Just activate a lightbox with no content and then hide the lightbox when the document is loaded.
This is a strange requirement and I would be interested in finding out your reason for doing this. Is there a problem or error that is ocurring. Perhaps you think the best way to prevent the error is to freeze the UI until the page loads.
I think that you should edit your question and describe what the underlying issue is. There might be a better way to improve your page.
I've seen this done with a simple overlay before.
Basically an iframe and a div that covers the page and has a high z-index is output at the beginning of page render. This is styled so it greys the page out and it also makes everything non-clickable. Then, once the page is loaded, a simple bit of javascript can be used to remove the div and iframe (or just set their styles to make them disappear).
I've also seen people attempt this issue by manually iterating over all controls on the page in JavaScript and disabling them. This is a horrible way to attempt it :)
The jQuery BlockUI plugin is another good option with lots of customization options.
