Creating your own forms designer

I would like start writing an application that will let my user design the interface by choosing some basic controls as Labels, TextBoxes etc. Once done I would like to save the layout in an xml file and be able later on runtime to reconstruct what user choose.
Is there anything similar ready and pre-made?
Can you suggest me the approach?
Any suggestion is welcome!
Cheers

Creating your own designer is a lot like building your own submarine in your basement. Programmers tend to take the quality of the Winforms or WPF designers as a standard of measure. Both are however the result of multi man-year efforts at Microsoft. Reproducing their work from scratch is a daunting task.
Best thing to do is leverage what's already done by them. Possible with the Winforms designer, this magazine article is excellent to help you get started. It is dated but I'm fairly sure it is still relevant, little has changed in Winforms in the past 6 years.

How to change the default look of a button or a form? (C#)

I want to change the appearance of the the form and the buttons, boxes etc which are laid on it. In java we can do that using Numbuzz look and feel or swing apperance. But i dont want to use the same traditional look of XP or any other OS which im gonna install my application, any one has an idea??

you could give Telerik a try and see if it's what you are looking for.
I'm using this library myself for application's design and i found it pretty cool. It has a lot of already made themes(like outlook controls...).
hope this helps

you could try to use WPF, WPF has been designed to make look and feel easily customizable.
or use vendor products like Infragistics WinForms (which allows you to specify Stylesheet kind of behaviour (search for infragisticsc stylesheet "ISL" ))

c# Tree/MindMap GUI

i am trying to research some gui technology for c# where i can display a tree view (opposed to the standard one provided.)
Essentially i want to have the gui draw a tree of data (as if you were going to draw a binary tree on a piece of paper or something) Then making each of the nodes clickable.
If this isnt available does anyone know of something where i could have a mindmap type GUI which shows links between elements and those are clickable?
I can guess people will say make one yourself, in which case i give up already ;) thats too advanced for me and as i am on a work placement i dont think i would be granted the time to make it as there are more pressing issues to get working first, like actually making the programme work!
Thank you

You can take a look at the controls in Kevin's WPF Bag-o-Tricks which has a WPF mind map style layout. Here is a nice example. If you want to use more professional components take a look at the product from Nevron Software, they have some great controls. There is also an opensource WPF graphing library - graphsharp (which I have no experience with, but I found a nice article by Sacha Barber). Since it's used in nDepend it must be pretty mature.
I hope you get some inspiration from those links :)

I also found XMind API for C#
https://xmindapi.codeplex.com/
It's free and looks easy to use.

Can I use silverlight to replace javascript and JQuery?

I have a webapplication that heavily uses JQuery. I would like to start using silverlight in its place if its possible. Instead of using jquery ajax features and other jquery features I would like to use silverlight. is this possible to do with silverlight?

Different tools. jQuery is best for manipulating the DOM. Silverlight is (ostensibly) best for rich internet apps, not manipulating the DOM. If your web application tries to create a cool UI using JavaScript, Silverlight might be a good fit to replace tons of JavaScript code.

If you application uses JQuery now replacing it with Silverlight will most likely not only entail redoing your JQuery features but also any HTML, CSS, forms processing and really everything about your application depending on what it does and how it is current designed.
I agree with Jonathon, they are really are two different tools.
Thanks.

Technically, Yes.
But you must understand that you will have to rewrite all your application from the bottom. Microsoft propose the RIA Services as the best practice design to use with Silverlight but with this will make you change all your design and even the Data layer.
So the answer is Yes. But you would better stick with jQuery.

#Luke101, you can design an whole website using Silverlight no probs. The question though is what is your target audience?
Silverlight doesn't come shipped with the browsers as yet so a lot of computers don't have it yet and so need to download it.
Given the amount of paranoia out there I think people are a little hesitant to download something when a broswer asks you to.
The environment you'll be working in i don't think will be HTML any longer and you'll be working in xaml.
Also consider your target browser. There are still a lot of people using <gasp> IE6 and i'm not sure if SL will run on it.
What is the motivation behind moving to SL? If it's because it looks cool, don't forget a lot of that comes down to design and if you're not a design person you're likely to make a bigger hash of it than if you were working in HTML.
You may also want to look at how you integrate with a designer. I know MS Expression is designed to make the job easier but it's still an early product. Also, does your designer know about Expression or Blend and know how to use it?
What I'm getting at is there is a large learning curve here which equates to someones money and you may not see anything for some time.

Yes.
Silverlight runs in the browser, jQuery (JavaScript) also runs in the browser. So they can technically replace each other, assuming all the functionality you want in one exists in the other (including support in various browsers).

Yes. Silverlight with RIA services can replace a jQuery AJAX site. Depending on the site's features, you may even be able to break up the features of the site into silverlight "widgets" for individual functionality. The danger is that Silverlight can quickly balloon into an application that is difficult to update (though it will guarantee cross browser compatibility). Silveright is entering version 4 and it's still not finished yet, so it's changing rapidly.

What is the best 3rd party GUI framework for application development in C#?

Examples could be Infragistics or DevExpress.
But I'm also looking for your opinions on other frameworks. It could even be WPF if that is your favorite.

Infragistics is very good. I think they have a better product for windows than the web. However, I get very upset using their products sometimes. I just want to find some hidden property, and it is impossible to find. They have way to many properties. Sure, you can do anything with their grid, but it should be easier. All of these vendors are leap frogging each other. You really have to compare all of them every year or two. I am currently using Infragistics on most web and windows project. If I could switch today, I would go to DevExpress for Web and Windows. Everything that Mark Miller and the guys at DevExpress produce is beautiful, and thoughtful. On a side point, you should check out CodeRush and Refacter. I may sound like a salesman, but I am not. I just could no longer code without CodeRush. It would feel like coding with one hand. If you are going to spend $1000 or more on a framework, you should also get CodeRush.

I've used Telerik RAD Controls for Asp.Net and it is a very comprehensive suite of controls that are easily converted to AJAX. The support is top notch, with the forum as a first place to go to for research before contacting the staff.
The client side API is fairly easy to understand, and they have good examples of mixed implementations with client and server side code.

I would say Infragistics

Haven't used it before, but I've heard good things about Telerik. My experience with the Infragistics Web components has been less than stellar. I found there were a lot of hidden features that I required, which were undocumented and had to go hunt around in the sample code for examples.
These toolkits can make sense for intranet applications but when you start providing it out on the web, the functionality can come at the cost of a bigger download for users. Just something to keep in mind.

What frameworks are you looking for? I currently use Janus Grids for grids on the winform side, but DevExpress has an awesome web grid that is amazing.

For current Winforms development my favorite is Infragistics. DevExpress seems to have more Silverlight controls in the works, but Infragistics may deliver.

I don't do much non-web development, but if I do I like to use gtk# for Mono (screenshots). It's much more fun and very easy to program then winforms. WPF looks good to, but I only tried an Hello World.

Infragistics has got good controls for Applications. WinGrid is one of the most important ones which would help you displaying information professionally and is quick.
the only drawback is the time consuming process of contacting their helpdesk or searching for the hidden properties. But they do work after you get to know them !

I would say go for DevExpress seems to be the most elegant, intuitive and well document suite out there.
To see their product offering in action demos.devexpress.com
Do the same for any component suite check out their demos and see which best suit you needs.
