Dynamic Navigation - Where To Return A Datatable From The Db Containing All The Pages Of Site
Jun 16, 2010
I am building a project in asp.net 4.0. My navigation will be database driven where i return a datatable from the db containing all the pages of my site, some will be top level while others will be children and sometimes children of children n-times. Im thinking of going down the nested repeater route and databinding from code behind, dynamically generating repeaters for children, but have read that this is not a best practice and should consider the listview control. Im wanting to build a list of links using an unordered list.
I picked up a new-to-me client who had a site built in ASP.net (which I do not host).I converted the site to PHP, which worked fine.I want to set up redirects for all the pages he had in the old site (it was a small site, so there was only 8 pages).As an example, the ASP.net url for the Contact page was www.domain.com/Contact - it is now www.domain.com/Contact.php (and so on).
For 301 redirects from one PHP page to another I normally use the .htaccess file:
In the application i come to products.aspx from five different pages.I have back button on the products.aspx page.How find from which page user navigated to products.aspx
I have a site with a few pages, and I decided to have my navigation button (to go from page to page) on my site.master page so every page looks the same. Two questions:
1. is that the correct thing to do? seems to work fine, I'm just not sure if it is proper or not.
2. with the navigation/buttons being on the site.master. How can I pass an "id" from one page to another.
I want the postbackurl to be "~/Inbounds.aspx?id=" a value from a textbox on the page you are leaving. More or less to pass a company name or ID number from page to page, so the queries know who the "owner" is?
I am having difficulties combing site navigation & securityTrimmingEnabled together.Please see my code below, let me know what am I missing:web.config file:
I've been tasked with managing the re-write of a very large enterprise application's UI. The existing UI was built upon an infrastructure which leverages the EntLib 3's PageFlow application block and the Web Client Software Factory. It performs horribly - part of the reason we need this upgrade so badly.
The problem is that these pageflows are very complex, using extensive conditional page transitions. When editing a data form, selection of a single value can determine not only what page you will reach when you click "Next", but whether a sub-pageflow is entered upon navigation instead, or a new pageflow is opened in parallel, etc. We deploy our UI in such a way where we control our API, but we allow certain licenses to purchase our UI code and extend/modify it as they deem fit. One of our selling points is that we allow the customer to "configure" or redefine pageflows using the VS designer.
In transitioning to MVC2 (or 3), we'd like to continue to offer configurable, conditional navigation throughout our various data entry page sequences. However, although I have developed the beginnings of our app in MVC2, I'm not sure the best way of implementing this data-entry pageflow "conversion". Sure, I've had my resources produce some solid designs - but all of them seem to require implementation of a complex controllerfactory. But one of the main attractions of MVC2 for me was its lightweight codebase and resultant performance gains - and I'm afraid that bypassing portions of MVC2 functionality by writing custom factories and the like will drastically reduce the performance of the app, making our UI refresh virtually worthless.
My initial thought was to write a custom filter that would implement the OnActionExecuted method. Every controller's primary POST methods would be marked with this attribute. Upon execution it would evaluate what view the user was on and look up the navigation event for that view in configuration. This config would have a default "next page"/"previous page" mapping, and can also allow for defining a type which would use conditional logic to determine the next page based on the posted model data. The actionfilter would use this type to find what route to navigate to next. I'd like to pick you experts' brains on this - does this seem like a solid design? Is it using best practices? And will it indeed perform better than a controller factory, or am I completely off-base here?
I Made label to had value from database and linked it . but the problem was it had only one value and i want it keep value when navigation thought site as.
x>y>z>.... this is my code < if (Request.QueryString["Category_Id"] != null) { Banar.ImageUrl = "Handlers/Banner.ashx?Category_Id=" + Request.QueryString["Category_Id"] + ""; using (SqlConnection conn = Connection.GetConnection()) { SqlCommand cmd = new SqlCommand(); cmd.Connection = conn; cmd.CommandType = CommandType.StoredProcedure; cmd.CommandText = "Navcategory"; cmd.Parameters.Add(Parameter.NewInt("@Category_Id", Request.QueryString["Category_Id"])); SqlDataReader dr = cmd.ExecuteReader(); if (dr.Read()) { LblNavigaton.Visible = true; LblNavigaton.Text = dr[i].ToString(); NavHref.HRef = "ListView.aspx?Category_Id=" + Request.QueryString["Category_Id"] + ""; } } } else if (Request.QueryString["ProductCategory_Id"] != null) { Banar.ImageUrl = "Handlers/ProCatBanner.ashx?ProductCategory_Id=" + Request.QueryString["ProductCategory_Id"] + ""; using (SqlConnection conn = Connection.GetConnection()) { SqlCommand cmd = new SqlCommand(); cmd.Connection = conn; cmd.CommandType = CommandType.StoredProcedure; cmd.CommandText = "NavProductcategory"; cmd.Parameters.Add(Parameter.NewInt("@ProductCategory_Id", Request.QueryString["ProductCategory_Id"])); SqlDataReader dr = cmd.ExecuteReader(); if (dr.Read()) { LblNavigaton.Visible = true; LblNavigaton.Text = dr["Name"].ToString(); NavHref.HRef = "ListView.aspx?ProductCategory_Id=" + Request.QueryString["ProductCategory_Id"] + ""; } else { LblNavigaton.Visible = true; LblNavigaton.Text = Page.Title; } }
How I can Make Navigation bar in my site as A>E>D>S>H. I tried more to find an example also I searched more but I couldn't find particular example searched
am wondering how to do the following... I have a registration system. When the user successfully registers, he is then led down a series of data gathering pages (for his profile) and then,finally, ends on his profile's home page where he can start to use the site. All this happens without ever logging into the system so, he is unauthenticated and unconfirmed. My question is, how does this happen? How can I allow my user to be unauthenticated (and unconfirmed, but this I understand) and use all aspects of the Web site? The way I have things set up right now, my code should be doing this:
case CreateProfileStatus.Success: //FormsAuthentication.SetAuthCookie(userName, false); Response.Redirect("NextPage.aspx", false);
i want to display my navigation in 2 horizontal menus, one on the top, the other on the bottom. I also want to use sitemap since it ease the maintenance of links. Is there a simple way to achieve this ? (I am not talking about Parent child, say i want to display the first 8 nodes in up menu and the left in the bottom menu.)
When i'm trying to debug or view pages of my site in browser asp.net dev server doesn't turns on pages automatically and when im trying to go by url it throws me an error See the end of this message for details on invoking just-in-time (JIT) debugging instead of this dialog box.

im am trying to write a forum using asp.net at the moment i have threads -> topics -> comments i realised that at the moment if users try to go back (from comments to topics and to threads), they can only use the back button in the browsers i am now trying to creat a menu like the one used in this forum (at the top "home >asp.net forums > general asp.net > getting started") as at anytime you can go back to see other topics at the moment i have tried to implement the following :
[Code]....
i thought that if i store get the topic_id from the address bar once, and store it in the session - then when i navigate to ..?comment_id - the topic_id would remain in the seesion i thought that in theory it kind of works, but now that i am trying to explain it here, i know that the session would then = to null. So i wondering is their any way to implement this navigation system
I've been rewriting my page into a master page for a bit now, problem I have is that I want the current page I'm in to be highlighted in the link.If you go to my website now gabriel-g.net and click on any menu item, it will let you know what current page you're on by staying underlined/highlighted.How can I accomplish this dynamic change in a master page -without having to recreate the menu in every page- with content holders?
the problem is: "~/Index.aspx" and "~/Column.aspx?ColumnId=1" are actual URLs and navigation bar: "Home > Column1" really works,
but "~/Content.aspx?ColumnId=1" is only the beginning part of actual dynamic URL, for example: it may be ~/Content.aspx?ColumnId=1&NewsId=12598 or ~/Content.aspx?ColumnId=1&NewsId=37215
all the previous Urls are articles of Column1 with same "~/Content.aspx?ColumnId=1" but are followed with different "&NewsId=number".
So, how can I realize this kind of navigation bar?
I am having a little difficulty trying to wrap my head around site structures. I have quite a large asp.net site, for which: Admins can see a user list, Each user can have many accounts, and for each account can have many items. I can picture this as a breadcrumb trail of editing a particular item. User List > Mr Bob > Accounts > BOB77 > Items > Item32 > Edit
User List = All the users Mr Bob = A user the administrator has selected from the User List Accounts = A list of the user's accounts 12BOB = The administrator has selected the account named 12BOB Items = A list of the items an account contains Item32 = The item that the administrator selected Edit = The action that the administrator wants to do. I can picture how this would look like if it was using ASP.NET MVC with the URL, but I am unsure how to map this out using Webforms, and in the physical filesystem.
This is what I have thought up about how I am guessing the physical structure would look like. Will this have to use session variables to achieve what I am trying to do?
/Users/User/Edit.aspx <- for editing a user /Users/User/View.aspx <- for viewing a user /Users/User/Accounts/Default.aspx <- for viewing all accounts /Users/User/Accounts/Account/View.aspx <- for viewing an account /Users/User/Accounts/Account/Edit.aspx <- for editing an account /Users/User/Accounts/Account/Items/Default.aspx <- for viewing all items in an account /Users/User/Accounts/Account/Items/Item/Edit.aspx <- for editing an item
Where can I read more about this kind of setup in a web application? Or, can someone point me in the direction of an available project that has this kind of layout?
I'm using a custom sqlsitemapprovider to get my site hierarchy out of the database and display my navigation. Now, I have the following main (parent) nodes:
Home - Products - News. What I want to achieve is this, suppose you click on products then a subnavigation appears like this:
productGroup1,productGroup2, productGroup3.
But when you click products, no selection was made from the subnavigation, how would I achieve that if someone clicks on products, the first product with content from the first productGroup1 shows up?
To visualize this: I click on Products -> Subnavigaton gets rendered -> PG1 - PG2 - PG3 -> page displays product1 of PG1
Is there as build in manner to accomplish this or how would one create a method to make this work?
P.S.:For my navigation, I'm not using any build in navigation controls, I'm rendering my menu as an html unordered list e.g: <ul><li></li></ul>
I'm trying to create an ASP.NET MVC master page so the site navigation on it will look like this:
Main Menu:Home | About | News Sub Menu: Home_Page1 | Home_Page2
The Sub Menu section should always show sub-menu for the currently selected Main Menu page (on the example above 'Home' page is selected) unless a user hovers the mouse on another Main Menu item (then it shows that item's sub-menu instead).
I am currently working on a document management system in ASP.NET 3.5 using the Telerik AJAX toolkit. It consists of masterpage with a title banner across the top and a RadTreeview down the left hand side for navigation through the site. The treeview uses a combination of static nodes and dynamic ones. The dynamic nodes are populated via a webservice. When a node is clicked the relevant page is navigated to, reloading the masterpage and displaying the content of the target page.
The problem comes from the fact the treeview's dynamic nodes are populated via a webservice and therefore as the user navigates through the tree to find a document the treeview behaves as you would expect. However, when you get to the bottom of a tree of dynamic nodes the navigation to the page of the navigateurl causes the relevant page to be loaded and then the treeview resets itself to a collapsed state. This means the user could be deep in a nest of documents but when they view one, the tree collapses and they have to start their navigation all over again. This limitation is not going to be acceptable from an ease of use perspective.
According to Telerik, this is the designed behaviour for performance reasons - the node only ever worries about populating the next set of nodes and therefore the treeviews state is not remembered in viewstate.
So, the meat of question is. Is the masterpage/async treeview navigation design pattern a valid one? Are there any other ways to have an ajax treeview on a masterpage, that remembers it's state when another page is navigated to? I have considered a siglepage/updatepanel/partial page rendering model but the opinions I've seen on the net infer that this is bad idea. It confuses users that expect back/forward browser behaviour to navigate through the site but in a single page world they would end up leaving the site.
I also thought that maybe using a single page container and an iframe may work but this seems to be moving away from the "standard" design pattern of using masterpages.
