<para>The <see cref="T:System.ComponentModel.INotifyPropertyChanged" /> interface is used to notify clients, typically binding clients, that a property value has changed.</para>
|
||
|
|
<para>For example, consider a Person object with a property called FirstName. To provide generic property-change notification, the Person type implements the <see cref="T:System.ComponentModel.INotifyPropertyChanged" /> interface and raises a <see cref="E:System.ComponentModel.INotifyPropertyChanged.PropertyChanged" /> event when FirstName is changed.</para>
|
||
|
|
<para>For change notification to occur in a binding between a bound client and a data source, your bound type should either:</para>

|
|
<list type="bullet">
|
||
|
|
<item>

|

|
|
<item>
|

<para>Provide a change event for each property of the bound type.</para>
