I have a school project to implement an AVL Tree and to do some kind of UI application to show how it works. I haven't done the code of the implementation yet, but that is not the trouble. I have no idea how to visualize my implementation. I want to do something like this: http://visualgo.net/bst.html# . Could somebody give me some directions about?
There are many options. I'll give you a few sulutions that seems to be easy to implement:
Write a simple WinForms applications with only one window. This window should contain only one control i.e. TreeView. You should populate it by recursively traversing your AVL tree and adding TreeNodes to it. It is simple and quick solution. The disadvantage is that the final result will not be like in your example.
You will get a similar effect if you use WPF technology and its TreeView and TreeViewItem classes.
The result similar to your example should be achieved with Microsoft Automatic Graph Layout. I used it quite intensively and I can recommend it. It is also not difficult in use.
I would suggest to use WPF. You create a Tree obvject that you bind to a hierarchical control.
As soon as you add items to the tree the UI will update. I would suggest it always over Winforms. Do yourself a favour and do not use them

I would like to know if it's possible to use a data template and a list system without the listview controller on xamarin forms.
You can definitely roll your own controls that use the templating engine. It would just take a whole lot of additional work with custom renderers for each platform etc. If you want to look into that you can check out the source code for Xamarin Forms since it's open source to see how they implemented the ListView. I think the negative voting is because this is quite a broad question that doesn't have an easy answer.
I am trying to find a way to create custom controls which lets the user drag them around on screen. This illustration shows roughly what I'm after:
So, this is basically a node network, where each node can have an arbitrary number of children and exactly one parent node. The connections between the nodes also has to follow them when they move, and bend appropriatly. I would also like all nodes to move when dragging the "canvas" behind them.
I know this is a lot of information, but basically I'm wondering if this is possible (and not too difficult) to achieve with WPF, and if it breaks with the philosophy of WPF to use it in this way. Is there a better way than using WPF for this? I've done a lot of research and can't find much info doing these things with it. Also, what is the most common ways to do this in Windows applications using .NET and C# if this seems way off?
Ok, I'll try to explain what I want to accomplish:
I'm quite new to WPF and XAML and I would like to create some domestic use applications with custom reusable UI. To be clear, I would like that every Window uses the same "Appearence" (specially the non-client area) without customizing every single one of them.
I've done some researches (obviously) and I found something that resembles perfectly what I'm trying to do: MahApps.Metro Template.
But I don't want to use some third party code because I like to have control all over my application and I want to customize what I want by myself. So I'd like to know what is the correct (and the best, maybe) way to do so. I've read plenty of posts about Window customizing but I didn't find anything that explained how to do that in that way.
I hope to have well-explained myself and I thank you all in advance for the help!
If you want to make custom UI in XAML you should learn to use Expression Blend. Here is a resource you can try -
Inspirational Textbox Styles (Source code available)
There are several videos available on youtube on Expression Blend for making custom UI in XAML. You can try that.
Are there any frameworks for building squarified treemaps in C# 2.0 WinForms?
Something similar to this:
(from http://www.codeproject.com/KB/recipes/treemaps.aspx)
Microsoft Research put one together.
Don't know how easy it is use.

I know you asked about WinForms, but I'm sure someone will hit this page when searching for WPF tree maps. This currently seems to be the best WPF freebie out there, though I found a few minor issues with it, it's still pretty good:

Check Janus Grid Ex should have a tree view...

What is the best way to serialize a wpf element tree to xaml so that I can get a design time representation?
XamlWriter.Save is having serious limitations, and it can provide only the run-time representation
Probably Microsoft don't want any one to build a customized xaml designer with out much effort :(
As I understand, there is no direct way to get the design time representation of xaml from the visual tree. :)
You can study the source code of Mole and create your own code that can do it for you.

We have a XAML designer product which emplores a custom XAML serializer. As it is, that is the most useful solution for us. However, with .Net 4, there are a lot of great options (and helpers) for doing exactly that task. So, if you're not afraid of a little betaness, I would start looking there.
Check out what Guy Burstein has to say about it.
Just un clip the xml unit eliminator and reroute both partial array procedures into the wpf tree. then create the object as a time line.
