MVC :: Frames In An Enterprise Web Application
Aug 20, 2010
I'm designing an enterprise web application interface based on an old system, and i planned to migrate the old frames layout to master page, but i noticed that if i use masterpages, the application users will be able to see the querystring or route path, and it could be a security issue. What is the best way to avoid this? Using frames? Masterpages with iframes as content? Masterpages with all PartialViews loaded by jquery?

Does MS have a sample enterprise application that demonstrates the use of different Enterprise library blocks (Logging, Dataaccess, Exception, Validation etc)? I am looking for something that uses best practices in using and integrating all these blocks in a single application.

I found a great control with example here for mvc It fulfills all my requirement but the problem is that it uses a js tree dll. Should I go on and used that example in my application? Do you people refrain from using 3rd party free dll in applications? How will I tell that it will not expire or not cause problem later on Forgive me if this is inappropriate question but thx in advance for any appropiate reply on this topic. just trying to get the point of view of you people on this

We have a huge ASP.NET web application which needs to be deployed to LIVE with zero or nearly zero downtime. Let me point out that I've read the following question/answers but unfortunately it doesn't solve our problems as our architecture is a little bit more complicated.
Let's say that currently we have two IIS servers responding to requests and both are connected to the same MSSQL server. The solution seems like a piece of cake but it isn't because of the major schema changes we have to apply from time to time. Because of it's huge size, a simple database backup takes around 8 minutes which has become unacceptable, but it is a must before every new deploy for security reasons.
Currently the best idea we came up is buying another SQL server which would be set up as a replica of the original DB. From the load balancer we would route all new traffic to one of the two IIS webservers. When the second webserver is free of running sessions then we can make deploy the new code. Now comes the hard part. At this point we would go offline with the website, take down the replication between the two SQL servers so we directly have a snapshot of the database in a hopefully consistent state (saves us 7.5 of the 8 minutes). Finally we would update the database schema on the main SQL server, and route all traffic via the updated webserver while we are upgrading the second webserver to the new version.
also share your thoughts regarding this solution. Can we somehow manage to eliminate the need for going offline with the website? How do bluechip companies with mammuth web applications do deployment?
Edit 1 (2010.01.12):
Another requirement is to eliminate manual intervention, so in fact we are looking for a way which can be applied in an automated way.
Let me just remind you the requirement list:
1. Backup of database
2a. Deploy of website
2b. Update of database schema
3. Change to updated website
4 (optional): easy way of reverting to the old website if something goes very wrong.

I have my validation configuration stored in validation.config in my Business Object project. The config file is set to copy if newer
The business object project is referenced by my web project, therefore, the validation.config copies to the bin folder of my web application.
In my web.config I have the validation configuration redirected:

I would like to convert my Frames-based web application to non-frames.Challenges:I have a frame of exploding tree menus (total tree around 1,000 menu choices - up to 5 levels of average 7 choices for each item). From this menu, one gets to the first content page (all dynamically created data pages). The content page can link to other content pages and so one.As the user navigates around in the right side, how can I have the display retain the exploded structure of the menu without using Frames (in a way that the browser back button will continue to work).Does anyone have an example of an application where there are many content sections on the screen which retain their state as the page is refreshed, without using frames?

My website currently uses frames. My index.html homepage looks something like this:

Well, apparently frames are way outdated, "element frameset is not supported" in XHTML Transitional 1.0 and "newer constructs are recommended." So, what do I do instead?

I'm working on an ASP.NET web application. There's a bill page which has two links to different pdfs of the same bill. When you click on one of the links it takes you to a ViewPDF.aspx page that shows the pdf. There's also an option to view both in a split screen so that you can compare them. When you click on this link it takes you to BillSplit.aspx which has a frameset and two frames that both point to ViewPDF.aspx. This all works perfectly.
The problem is that if an error occurs while pulling up the pdf. The application has an error page that has a few links back into the application. If you use one of these you can go back into the app and continue but now inside the frame. The URL still says BillSplit.aspx but the application is completely unaware of this since frames are HTML elements not asp.net controls.
What I would like to do at this point is detect that you've returned to the application and close the frame you aren't using. Essentially I'd like to redirect you away from BillSplit.aspx and to the page you're actually requesting. I'm pretty sure this would need to be done in Javascript either on the BillSplit page or on the pages that you go to later. So I guess what I'm asking is, is there a way to ensure that the BillSplit.aspx page and it's two frames point only at ViewPDF.aspx?

I'm having an aspx page with 2 frames, one is the header and the the other one is content frame which i'm trying to load it dynamically. Everything is fine. Let me explain my scenario
On the header frame i'm having 5 link buttons and when a link button is clicked i'm passing a hardcoded Page URL to the frames containing page and then trying to load that page in the content frame.
Below is my code, Everything as far as i know are in right place, but i cannot see the page in content frame..
Header.aspx.cs
[Code]....
Then checking frameURL querystring in default.aspx page load:
[Code]....
when the querystring is null, the SiteSummary.aspx page is getting loaded in content frame without any issue, but when there is a querystring value the page is not being loaded.
Here is my Default.aspx page

How can I integrate my aspx page into my existing php/html frameset page? So far I've designed the aspx page, now I need to know what to put in my button_click event.
In javascript I use this to get one textbox's text:
var t1=window.parent.text1.getText();
and this to set another textbox's text:
window.parent.text2.setText("text");
How can I tie this in to my button_click event?

I am using Enterprise library for my data access. when I am running the application, at the CreateDatabase() statement I am getting this exception:
Microsoft.Practices.ObjectBuilder2.BuildFailedException was unhandled by user code Message="The current build operation (build key Build Key[Microsoft.Practices.EnterpriseLibrary.Data.Database, null]) failed: The value can not be null or an empty string. (Strategy type Microsoft.Practices.EnterpriseLibrary.Common.Configuration.ObjectBuilder.ConfiguredObjectStrategy,index 2)" Source="Microsoft.Practices.ObjectBuilder2"
Now, I googled a bit and I found that I have to place
<dataConfiguration defaultDatabase="LocalSqlServer"/>
but I don't know where. Is it the right solution? Also, at the time of installing enterprise library I didn't see any connection string statement? So, I wonder how it will take the connection string from web.config file. In the connection string section of my web.config file I have:
<remove name="LocalSqlServer"/>
<add name="LocalSqlServer" connectionString="Data Source=MSTR;Initial Catalog=USERDb;Integrated Security=true;" providerName="System.Data.SqlClient"/>

I wanted to get any feedback (put out a feeler) for how the enterprise library plays with linq-to-sql generated classes. I was considering using the validation handler to provide validation logic/display to the UI level. I am considering the caching handler, validation, and authorization handlers primarily.

I have a question about validation. Basically how the MVC framework is setup it can use DataAnnotations. It calls TryValidate in a controller which does some other black magic, and poof, you have a ModelState with validation results. Now to extend this validation you can create a validator and then provide custom validation on both server and client side. Here is the problem... what if you dont want to hard code all of the validation in the classes? I would like to use what Microsoft has already provided in the Enterprise Library [URL]for validation. I will be using both DataAnnotations and configured rule sets. Of course I could just put the code in each action, but that is so 1999. As I see it the MVC framework falls short by not allowing us to use the config for such things. Why is the validation so specific for MVC? Why could it now have used the Enterprise Validation? I wrote my own abstract controller and put in Enterprise Library validation and it worked GREAT!!! So why am I here? Well, surly there must be a better way... do I really have to write my own controller abstract class to change the validation?
So if you think you know how to solve this problem, you must provide a solution that does this:
Uses DataAnnotations AND Configuration RulesCan validate the SAME in a console application (could really be any non-web app) and MVCI do see that MVC 3 adds a little more support for validation which was really needed. It supports IValidatableObject, which allows you to validate the whole Model... its nice, but now we have 3 ways to do that same thing... granted the former 2 (DataAnnotation on the class, and a Validator for the DataAnnotation) could not pass the error to the correct place in the view. Now if we could just support all of this validation in a place what any type of application could use it. In my use case I will run validation on the MVC app, perhaps some other apps, and on an ESB.

I'm trying to learn the Enterprise Library. I found this useful code sample to get data from a SQL database. But I tried to send data via a parameter. I'm also using the UPDATE, DELETE, and SAVE methods. Can you give me a similar sample? I'm using Enterprise Library 4.0.

Recently i have joined a new project that is to be build from scratch.(goal of the project is to reach the users across boundaries : windows, web & mobile)
I follow architecture having following layers:1.Presentation Layer 2. Logic Layer(BLL) 3. Business Objects 4. Data Access Layer.
But this time i wanted to use new technologies Microsoft have introduced like Entity Framework 4.0 , WCF services.
So i have thought of creating the layers like
1.Presentation 2. BLL 3.Services 4.Business Objects 5.DAL
but i am in confusing state how to use Entity Framework. in the above layered diagram.If there any flaws in the above layered diagram do guide me.I have heard of Microsoft Enterprise Library(MEL) 5.0. What exactly it is?
Will i get benefited with MEL 5.0.

Has any one used Microsoft's Enterprise Library, if so what parts of it did you use? I am using building a website (I guess the client app type is not important, it can be a Windows app as well) with all the architectural layer, and I am specifically interested in the exception handling, logging and caching blocks for now. Any one used these, what were the good and bads of your experience with, any alternatives that you rather decided to use? Performance is a thing that I am also interested in. I am looking for a decent exception handling framework which is how I came across the exception handling block. Anything other out there? Is it a wise idea to use the data access block with an MVC application seeing that everybody is the repository pattern with an ORM framework? I am still researching frameworks, so I would like to hear as many opinions.

The CachingCallHandler included in Enterprise Library 4.1 was removed for Enterprise Library 5.0+. The documentation refers to using the Enterprise Contrib Library to get this functionality, if needed.My questions:Where is this functionality in the Enterprise Contrib Library?Does this work with Enterprise Library 5.0?This is the only functionality I have a definite need for from Enterprise Library but may want to use the validation, as well. I don't see any reason to start with 4.1 when newer versions already exist. But, I'm slightly confused about where to find this functionality.Of note, I don't see this method listed on their page.. still searchingI think this is the namespace, and I don't see the file in the latest download.

I just downloaded entLib 4.1. Part of the download process included a DOS bat file that ran for a while. Being completely new to the Enterprist Library I have no idea how to use the Enterprise Library. Online support mentions something about accessing the blocks through the References folder in the Solution Explorer - but I don't have one in my solution explorer. How do I get the References folder to appear so that I can start figuring out how to use the application blocks?
