    Implements INotifyPropertyChanged

Remarks

The ModelItem class represents a single item in the editing model. An item can be anything from a window or a control down to a color or an integer. You may access the item’s properties through its Properties collection and make changes to the values of the properties. A ModelItem is essentially a wrapper around the designer’s underlying data model. You can access the underlying model through the GetCurrentValue method.

Note

You should never make any serializable changes to an object returned from the GetCurrentValue method. The changes will not be reflected back in the designer’s serialization or undo systems.

Note

Use the invariant culture when setting model item values by using strings.
