I'm a little lost as to how to write a class that will take in arguments from the .Add function of a List<>.

List<SnapShot > LiveSnapshot = new List<SnapShot>();

public class SnapShotList : List<SnapShot> {}

SnapShotList snapshots = new SnapShotList();

1st question:
How can I create a class to be used like XmlNode. XmlNode can be XmlElement or other types. I want to use similar approach. I need it, because I want draw other type of controls within one control.

2nd Question:
My Control is Inherits Control class. How can I hide some properties and/or change its description.

Okay, well then create a simple interface for your object and have a toString method that can convert it to the correct output. Look at the XML classes and interfaces, they all share a common.

This is more complex. You would have to use some kind of logic to display the node as such. HTML/WPF/SilverLight/WinForms all do it differently.

Question: What are you creating the control in? WPF?

I have read a Book about creating Custom control, however i need data layer that behaves like XmlNode. I will look at the interface.

Will look at it. If I coudn't use, then I would use Object, but I would rather avoid Object
