I am in the process of designing a .net windows forms application that uses metadata to drive the UI. Apart from finding http://msdn.microsoft.com/en-us/library/ms954610.aspx, I have nothing much to look forward to. Anyone here worked on metadata driven User interfaces? What are the implications of following this methodology and any pointers would be greatly helpful.
The most obvious answer would be that Microsoft have themselves embraced this concept through their use of Xaml in Windows Presentation Foundation which replaces WinForms (to an extent).
If you want to stick to a WinForms, you may want to consider MyXaml which is kind of a homage to Xaml for WinForms!
You may want to check out Evolutility CRUD framework. It is an open source metadata driven framework for CRUD generating all UI at run-time.
It comes w/ source code (in C# and JS) and many samples.

You may try this with HTA. Sometime back I created a metadata driven application using HTA and XML. I created XAML like structure and HTA-VBScript code to parse this structure and render diffent types of UI elements along with validations.
Check the Andromeda project out, which does so extensively. Too bad the stack isn´t .NET friendly (PHP, Postgres, Perl).

I'm looking for a set of Javascript based UI components for a web app I'm building and have found that many of the best looking web apps were built with the Capuccino framework; see http://www.getflow.com/, http://www.picsengine.com/home/ and http://timetableapp.com/ for examples.
However, I'm not a Cocoa developer and have no interest in learning Objective-J. Ideally, I'd find a set of components that provide the visual end result of Capuccino apps without the underlying weight of the framework.
I have seen the Aristo jQuery UI them (http://taitems.tumblr.com/post/482577430/introducing-aristo-a-jquery-ui-theme), but jQuery UI just doesn't seem to have the depth of components available in Capuccino.
I realize this may be a long shot, but I figured it can't hurt to ask. :)
Thanks.
As another option, there is jQuery UI: nice if you are already familiar with jQuery, with the plus side of not being too heavyweight, but may not have all the components you need pre-defined. A nice thing is that it encourages to write the HTML in a way that degrades gracefully when your application in older browsers.
Maybe sproutcore is an alternative for you, although it requires you to hand-code everything in javascript from scratch. It offers most basic components and is easily adjustable to your personal design goals. Sproutcore is used in Apples Mobile Me and in some other big projects.
Another possibility might by vaadin which offers a rich set of prebuild controls and is based on Googles GWT javascript compiler. But it only makes sense if you are developing in a java environment.
I'm trying to find a CMS that can be incorporated into an existing MVC3 app.
I've played with N2, and can't get the damn thing to work in VS2010 or with .NET 4.
Umbarco doesn't appear to support MVC yet
Orchard looks great, but wants to own the whole application.
DNN is just a mess.
Any other brilliant solutions?
Post-mortem Dec 2011
This is an old post, but I thought I'd share my experiences with Orchard, and why I decided to go a different direction.
NHibernate
Aside from the very large number of transactions per page (literally dozens in some cases), each and every query was executed using sp_executesql. While not quite as bad as using Exec(), this rubs me the wrong way. Currently, my database is locked down so that applications can only execute stored procedures - that is, they can't perform select/update/delete, list entities such as tables, get any metadata, etc. This is a requirement for tier-wise unit testing, compile-time verification of the database, security and encapsulation of database logic from the application code.
Source Deployment
Orchard requires that the entire source for your site (views, .cs source files, etc) is deployed to the production server. The sheer number of source files that need to deployed boggles the mind.
Integration with an existing application
The manner in which Orchard is structured effectively requires it to be the point of entry for the web application. This means that you're going to spend some time modifying and reimplementing your app to get it to play nice with Orchard.
Conclusion
There were quite a few other issues that I encountered, but those are the highlights. Individually, each of those could have been a deal breaker. Together, they removed Orchard as a viable solution.
I'm now evaluating Telerik's Sitefinity. It's not MVC, which saddens me, but:
The admin interface is extremely powerful. Aside from a master page and some stylesheets that I put together in VS, we've been able to handle all of the layout via Sitefinity's admin tools.
I mean, it's really powerful. You can use the admin interface to edit the admin interface. Think about that for a minute.
Widgets are implemented as ASP.NET user controls. Most of my existing controls just dropped right in with zero modifications.
Database access is handled via Telerik's OpenAccess ORM. While Sitefinity doesn't natively use stored procedures, OpenAccess fully supports using them for all operations. Also, according to Telerik, OpenAccess does not, in any way, rely on reflection, which provides significant performance benefits in heavy-load apps.
There are several solutions available for using Razor markup within widgets, which is one of the great benefits (to me) of using MVC. Also, I've been told that native Razor support is in active development.
It's not free. In reality, however, a few grand barely breaks the noise floor in terms of development time.
Super crazy fast. Startup time is a bit on the slow side, but once it's running, it's very quick.
Built on top of Telerik's awesome, proven RAD controls.
Apologies for the long post. Hopefully this will be helpful.
You might find these projects useful. You can probably model a simple CMS based on one of their projects.

Try Web Noodles..The new CMS developed using mvc3. WebNoodles.It is easy to integrate .But the thing is it is still in beta stage..But you must give it a try ...
I'm developing a WinForm app in c# 4.0 and would like other (non-developer) colleagues to contribute writing a context sensitive end-user helpfile. First I thought I could use "HTML Help Workshop" from Microsoft, but it seems outdated (Vista and Windows 7 not supported).
Then I've looked at Sandcastle, but the documentation is lacking and I wonder if it is suitable for non-technical users to write end-user documentation.
So I read about RoboHelp, but it's way to expensive for me.
I'm getting lost in all the information that is available about helpfiles. Can someone help give some best practices or information on what tools to use and what output format I should target (still chm or other).
Great question. I like your idea of non-developers contributing to the end-user documentation.
This idea might motivate users and testers of your application to easily contribute to the documentation.
The first thing that comes to my mind, is using a some sort of wiki engine. You could build a simple function in your WinForm application, that fires up a browser and directs in to the wiki. You could use the context from which it is called to build up an url; e.g. http://dev-wiki.mycompany.com/LoginForm?action=edit. Here the name of the form ("LoginForm") is used in the url of a wiki page.
Alternatively, you could simply use the embedded web browser control for WinForms to access the wiki. That would look something like:
var url = GetWikiUrl(myForm);
browserControl.Navigate(url);
This would be very easy to embed in your application.
In a controlled (office) environment, this would be very easy to set up. In you production environment it might be a bit more difficult, but still doable. It might leverage some end-user contributions too.
For writing documentation, I use sphinx.
It lets you document in plain text and has various output formats (chm, html, pdf etc.).
Some of these (chm, html) can be used as context-sensitive help sources.
However simple, the sphinx user-interface (text editor and make file) might not be suitable for non-technical users.
I would recommend to use Help+Manual for creating CHM documentation. It's similar to MS Word and any PC user can start to contribute doc development after short education.
But this tool isn't free :(
I'm a junior VB.net developer with little application design knowledge. I've been reading a lot of material online regarding different design patterns, frameworks, and methodologies. It's become a bit confusing for me.
Right now I'm trying to decide on what language would be best suited to convert an existing VB6 application (with SQL server backend.) I need to update the UI and add more user functionality and reporting capabilities. Initially I was thinking of using WPF and attempting the MVVM model for this big project. Reports would be generated from SSRS.
A peer suggested using ASP.net and I don't have enough experience to determine what would be better. The senior programmers here are stuck on using VB6 and don't have any input on what to use. They are encouraging me to use the latest technologies.
This application would be for ~20 users in a central location. Ideally I would stick to a Microsoft .net language. Current interface is similar to a datagrid table where the user would click in to see the detail of each record. They would need to have multiple records open at any given time.
I look forward to all the advice I can get.
EDIT 2010/04/22 2:47 PM EST
What is your audience? Internal clients within an intranet
How complex are the interactions you expect to implement? not very... displaying data from SQL server to UI. Allow user updates to said data. Typically just one user modifying a record.
Do you require near real-time data updates? no
How often do you expect to update the application after the first release? twice/year
Do you expect a well-defined set of client platforms? Yes, windows xp environment, potentially upgrading to Win7. Currently in IE.6 moving to IE7 or 8 within a couple of months.
Do users need access from anywhere? No, just from their PC.
What would be wrong about building a simple ASP.Net application in VB.Net using Gridviews for allowing the data access and manipulation? Seems like a simple ADO.Net trial application if you aren't familiar with it in the beginning you will be by the end. CRUD applications are pretty common so it shouldn't be too hard to build it and then refine it as more requirements become apparent.
Sounds like you need to use a web-based solution--this eliminates alot of your potential distribution woes with multiple users. You could use silverlight, but if you are locked into SSRS, this might not be the way to go.
The examples that Microsoft's Patterns and Practices provides are quite helpful:
about a half-dozen simpler QuickStarts which touch on specific issues
the StockTrader reference implementation, which is a fairly rounded application
but it lacks a more useful base application that reads and writes to a data source (XML or database), allowing users to login, edit data, logout, etc. (something like what ASP.NET MVC comes with).
Since Prism applications can get quite complex and lengthy (the StockTrader example is almost 300 files without tests), it would be helpful to have an application that takes care of the CRUD bulk that everyone needs to build for most apps anyway.
Does anyone know of any data-editing Prism example apps out there?
Here (http://petedoesstuff.net/Blog/?p=79) you'll find a bunch of links to the samples of using the Prism.
Particularly, LateNight (http://code.google.com/p/cwpfsamples/) may be what you need. It has login screen and data editing functions.
Its feedback I've seen a lot of. I'll pass this onto the Team and see if we can get some more examples put online around this space.
I'm currently writing my own demo app now, so i'll also try and put that online via my blog.

The reason data access was left out of the Prism RI is because it is largely irrelevant to Prism. I would think you're better off looking at something like DinnerNow for those kind of things.
