C# "+" sign windows properties

I have the class AppForm inherited Form with property AppIconForm (class).
I want at design time "+" sign appears on the edit IconForm property in the properties window and the child properties ( CloseIcon and MaximizedIcon ) appear. Thanks! :)
public partial class AppForm : Form
{
AppIconForm iconform = new AppIconForm();
public AppForm()
{
InitializeComponent();
}
public AppIconForm IconForm
{
get { return iconform; }
set { iconform = value; }
}
}
//the code of AppIconForm class
public class AppIconForm
{
Icon closeicon;
Icon maximizeicon;
public Icon CloseIcon
{
get { return closeicon; }
set { closeicon = value; }
}
public Icon MaximizeIcon
{
get { return maximizeicon; }
set { maximizeicon = value; }
}
}

Use BrowsableAttribute
[Browsable]
public Icon CloseIcon
{
get { return closeicon; }
set { closeicon = value; }
}

Get info about something itself

I have this mistery:
public class UIWindow : Control
{
public PythonDictionary Variables;
public PythonTuple Children
{
get
{
if(Variables.has_key("children"))
return (PythonTuple)Variables["children"];
return null;
}
}
public UIWindow(PythonDictionary variables)
{
Variables = variables;
LoadChildren(Children, this);
Tag = "window";
}
private void LoadChildren(PythonTuple children, Control parent)
{
--recursive loading
}
}
Then i want that a class gets information about itself
public class UIText : Control
{
private PythonDictionary Myself
{
get
{
}
}
public string Name
{
get { MySelf["name"]; }
set { Myself["name"]; }
}
public UIText(Control parent)
{
Parent = parent;
Tag = "text";
}
}
I already know that my info is type of pythontuple because the LoadChildren of UIWindow did load all children from pythontuples, but how do i have reference to myself?
private PythonDictionary Myself
{
get
{
}
}

How to change name of xaml attribute in C#?

I want to serialize objects of class to xaml format. However, all of the properties name of class are directly serialized and I can't change their name.
I've used the
[DataMember(Name = "NameToChange")]`
attribute, but this still not solve the problem.
Please help me on this.
Here is the class:
public partial class XObject
{
[DesignerSerializationVisibility(DesignerSerializationVisibility.Content)]
public string AtName
{
get
{
return this.Name;
}
set
{
this.Name = value;
}
}
[DesignerSerializationVisibility(DesignerSerializationVisibility.Content)]
public string AtType
{
get
{
return this.m_TypeToken;
}
set
{
this.m_TypeToken = value;
}
}
[DesignerSerializationVisibility(DesignerSerializationVisibility.Content)]
public string AtSerialize
{
get
{
return this.m_SerializeToken;
}
set
{
this.m_SerializeToken = value;
}
}
[DesignerSerializationVisibility(DesignerSerializationVisibility.Content)]
public List<string> AtValue
{
get
{
return m_Values;
}
}
[DesignerSerializationVisibility(DesignerSerializationVisibility.Content)]
public Dictionary<string, XObject> AtAttached
{
get
{
return m_AttachedAttributes;
}
}
[DesignerSerializationVisibility(DesignerSerializationVisibility.Content)]
public string AtDynamic
{
get
{
return m_DynamicValue;
}
}
public void UpdateToken()
{
AtSerialize = (true == HasAttribute(AttributeNameToken_Serialize)) ? GetAttribute(AttributeNameToken_Serialize) : null;
AtType = (true == HasAttribute(AttributeNameToken_Type)) ? GetAttribute(AttributeNameToken_Type) : null;
foreach (XObject member in this)
{
member.UpdateToken();
}
}
private string m_TypeToken = null;
private string m_SerializeToken = null;
}

ASP MVC 5 Creating Treeview with check boxes on Leafnode

This is my model structure from which I want to use to create a treeview, with checkboxes on leaf nodes:
public class CategoryEntity : BaseEntity
{
public CategoryEntity()
: base()
{
}
private Guid _categoryId;
public Guid CategoryId
{
get { return _categoryId; }
set { _categoryId = value; InvokePropertyChanged("CategoryId"); IsDirty = true; }
}
private string _categoryname;
public string CategoryName
{
get { return _categoryname; }
set { _categoryname = value; InvokePropertyChanged("CategoryName"); IsDirty = true; }
}
private string _categorydescription;
public string CategoryDescription
{
get { return _categorydescription; }
set { _categorydescription = value; InvokePropertyChanged("CategoryDescription"); IsDirty = true; }
}
private string _categorytype;
public string CategoryType
{
get { return _categorytype; }
set { _categorytype = value; InvokePropertyChanged("CategoryType"); IsDirty = true; }
}
private Guid? _parentcategoryId;
public Guid? ParentCategoryId
{
get { return _parentcategoryId; }
set { _parentcategoryId = value; InvokePropertyChanged("ParentCategoryId"); IsDirty = true; }
}
}
The problem is that I am new to MVC and I don't know which controls to use to display this values in a tree structure. Can anyone suggest a way of doing this?

What is the proper way to handle an array of one class in another class?

Here are two simple classes to illustrate my question:
class Widget
{
private int _widgetID;
public int WidgetID
{
get { return _widgetID; }
set { _widgetID = value; }
}
private int _categoryID;
public int CategoryID
{
get { return _categoryID; }
set { _categoryID = value; }
}
private string _widgetName;
public string WidgetName
{
get { return _widgetName; }
set { _widgetName = value; }
}
}
And them the second class:
class WidgetCategory
{
private int _widgetCategoryID;
public int WidgetCategoryID
{
get { return _widgetCategoryID; }
set { _widgetCategoryID = value; }
}
private Widget[] _widgets;
public Widget[] Widgets
{
get { return _widgets; }
set { _widgets = value; }
}
private string _widgetCategoryName;
public string WidgetCategoryName
{
get { return _widgetCategoryName; }
set { _widgetCategoryName = value; }
}
}
How would I handle this situation in the most efficient way?
Also, so you know, I will need to nest other classes the same way below the Widget class.

You should create a read-only property of type System.Collections.ObjectModel.Collection<Widget>.
Collection properties should be read only
Use Collection<T>
