User interface design

Hi all,

I am looking for some advice on how to approach implementing a user interface with c# express (2008).

The basic idea I have is to have a tree control on the left of the display and then based on the tree node selected a different form will be shown on the right of the display.

|                |                                                                   |
|                |                                                                   |
|     1         |                              2                                   |
|                |                                                                   |
|                |                                                                   |
|                |                                                                   |
|                |                                                                   |
|                |                                                                   |

So 1 is the tree control, when a user clicks on a tree node a different set of controls will be shown in 2.

What is the best way to go about this:

1. Create an MDI app with the tree control as a user control.  Each of the right forms (2) as a seperate user control with the required text boxes etc on them. When the user clicks on a tree node the required form will be made visible, the rest hidden.

2. Create a simple form with a tree control on the left and then dynamically create the different controls when the user clicks on a node.

3. Some other way!

Any links to tutorials or samples that have this kind of layout (1,2 or 3!) would be much appreciated.

Thanks in advance for you time.
