I'm very new to MVC (just started 2 days ago), and I would like to know what the best practice is for outputing HTML.
I have a model named Tools.cs which contains the code below. It uses a stored procedure to return a recordset of menu items, and another to return a second level of menus for each first level menu. In another function, I then loop through the recordset and generate the HTML code to display the menu in a string, which is then returned.
I then have a controller MenuController.cs which calls the GetMenu method and puts the returned HTML string in the ViewData["RightMenu"].
I then have a view which displays the result.
My question is: would it be better practice to return my datareader to the controller into ViewData["RightMenu"], and then loop through it and construct my HTML in the View instead?How would I get that to work with that second level of menus?[Code]....
Above Web Method compiles but does not work. Originally was using Console.* stuff, but that didn't work either. The string arguments are remote URLs. What's wrong with this code?
I'm building a website at the moment, I've some html fragment that is being stored into the database, I've been reading around that inserting HTML at runtime poses security risks by using the InnerHTML property of any html tag with runat server on it. So, my question is there any alternative way to safely display the html code and won't pose security risks and is it best to assume any textboxes on any given page is dangerous and process the text in the textboxes with Server.HtmlEncode before I store it to database?
In order to keep the look and feel of my web forms optimized for a mobile device, what table/table row/table column border-style and position settings should be used (i.e. fixed, relative, static, etc)?
I have 50 checkboxes that I need to write onto an aspx page. Each checkbox comes with 3 textboxes.
Example:
chkbox State Name donation new donation chkbox CA Sam 10 15 chkbox AK Sam 15 20
Now this shall go for all 50 states, depending on which states the person wishes to donate. In each state's row shall be a checkbox. So initially the page shall have value 0.00 in donation and new donation checkboxes, but all 50 states shall be visible. When the person puts a value of donation in certain state, that state shall get "checked" value and the donation, after submitting. On reloading, the value shall be populated automatically and checkbox checked automatically.
How do I make these 50 checkboxes in VB.NET? Do I have to write the table in .aspx with 50 <tr> tags, and then have VB.NET code populate it? Can I otherwise dynamically write these checkboxes from VB.NET code?
I have a file, a.pdf, stored on a SharePoint server behind Windows authentication. I want to make a.pdf available through another Web app with forms authentication. Basically, link is clicked and up pops the open / save as dialog for the pdf (or other document file) I've set up my HTTPWebRequest and passed credentials, getting my data into a stream (file.GetResponseStream).
I've tried converting the stream to a byte array and then using response.write or response.output.write with no luck (stream not seekable) I've tried using a streamreader and doing a response.write(streamreader.readtoend()) and response.write(memorystream.toarray(),0,memorystream.toarray().length) with no luck (the message received from the server could not be parsed).
return Json will serialize my string to a jSon string, this i know but it likes to escape for some reason, how can i get rid of it? for info this is how i call it with jQuery:
I have a web application where users can upload the photo. I do have a windows service running which takes the uploaded photo and crops it to different sizes. This runs in a specified interval. Photo will be visible to the user once after it's cropped. So once user uploads the photo and photo cropper has not yet run, they wont be able to see the photo. Due to this behaviour user thinks that there was some error uploading the photo and they will upload it again and again.
where the photocropper runs immediately when the user uploads the photos which is queued.
I'm about to begin an ASP.NET MVC project and I'm not sure how to approach an aspect of the design. Basically, there is a user site and an admin site. In the admin sites, administartors design a form and send an e-mail link out to a handful of people. When the users click on the link, they are sent to the form.
Essentially what I'm wondering is what are the best practices when the model resembles looks more like a dictionary than a table?
For WPF, there's the Microsoft Patterns & Practices's Prism project.
Prism provides guidance designed to you more easily design and build rich, flexible, and easy-to-maintain Windows Presentation Foundation (WPF) desktop applications, Silverlight Rich Internet Applications (RIAs), and Windows Phone 7 applications I was wondering whether a similar project (reference implementation) intended for software developers building WCF applications exists.
In our main internal project (a .Net WinForms rich client app), we don't talk directly with the database but instead fetch and update data with ASP.Net web-services that we also control. Our current setup is giving us some bottlenecks. For a new smallish project, we want to try WCF. Objective question: Where do I find a not-too-basic WCF reference project?
In my experience building web applications, I've always used a n-tier approach. A DAL that gets data from the db and populates the objects, and BLL that gets objects from the DAL and performs any business logic required on them, and the website that gets it's display data from the BLL.I've recently started learning LINQ, and most of the examples show the queries occurring right from the Web Application code-behinds(it's possible that I've only seen overly simplified examples). In the n-tier architectures, this was always seen as a big no-no.I'm a bit unsure of how to architect a new Web Application.
All too often I find myself being required to design pages that flow through a series of steps. 1) Select from a set of options. Submit.2) Populate a page with results. Make changes. Submit.3) Do something based on the previous results. Submit.4) Confirm previous actions. Submit.5) Goto 1.An ecommerce site with shopping cart would be a textbook example of this.Now, there are any number of ways to deal with this. My question is, what is the recommended way to do it in asp.net? In PHP or ISAPI I would just use standard html controls, get the post data and do stuff with it, each on a different page
We are working on a project which has lots of routes that can be changed on-the-fly or new routes can be added dynamically. What are the best practices about managing lots of routes and adding routes on-the-fly without recompiling? Reading-Writing from-to database or from Xml Document in Application_Start?
Here is the code of my Repository class:You see, I use singleton here. Also you see, there is a data context as class variable of Repository class.The main reason to use singleton here is a wish to avoid using 'using(NorthwindEntities context = new NorthwindEntities())' in every function.
[Code]....
This Repository is used in ASP.NET application. So only instance of NorthwindEntities (context) is used everywhere and that's why I never dispose it.So my question is: Won't this code cause connections to the DB that are not closed?

I would like to know what are the best practices in using Javascript in ASP.NET in a pre-AJAX and pre-jQuery era. What I meant by pre-era is not the time before AJAX/jQuery was created, but rather the time before it is popularized and widely adopted (by a significantly large number of programmers).i.e. Is it good thing to store the script in a string variable and register it on demand (RegisterClientScriptBlock) or on startup (RegisterStartUpScript)?Although in using Javascript in ASP.NET, its usage in PHP and JSP are also welcome.

This question is for ASP.NET and SQL Server developers. What are your best practices with respect to setting up your development and test environment? I'm interesting in the following issues: How many tiers do you recommend and what goes on on each tier? Just dev, test, and production or perhaps dev, test, staging, and production? Which types of applications and/or servers should run on actual physical hardware and which can get away with a VM? What are your strategies for loosely coupling users from web sites, web developers from their web/app/DB servers, and DB developers from their DB servers?
How do developers stay "DRY?" What are the pros and cons to putting web, app, and DB servers on their own machines? Does putting servers on separate machines in order to minimize contention for a machine's resources trump any NIC and network latencies that might be introduced by putting them on different machines? How do you configure your web apps to minimize contention for resources (e.g. virtual directories, separate application pools, etc.) How and how often do you refresh your databases on each tier? Do you just refresh the data or both the data and objects?
We are in the midst of developing WEB application using .NET. so, i would like to know the Best practises for ASP.NET development, SQL server db, IIS security and network security as well. Where to get the information? I googled for it, but i cannot get the complete set and the info was updated 7 years ago. [URL]
