Syntax

'Declaration
Public MustInherit Class ModelItem _
    Implements INotifyPropertyChanged
'Usage
Dim instance As ModelItem

public abstract class ModelItem : INotifyPropertyChanged

public abstract class ModelItem implements INotifyPropertyChanged

Remarks

You may access the item’s properties through its Properties collection and make changes to the values of the properties.

A ModelItem is a wrapper around the underlying data model of the designer. You can access the underlying model through the GetCurrentValue() method. NOTE: Any changes you make to an object returned from the GetCurrentValue() method will not be reflected by the serialization and undo systems of the designer.
