Difference Between Dependency Property and Normal CLR Property in WPF
The Normal CLR property and the dependency property look quite similar but the dependency property is more powerful and has more features. In WPF, dependency properties are used in Animation, Styles, Triggers, Templates, Validation, Data Binding, Layout etc.
Syntax Difference Between Dependency Property and Normal CLR Property
Syntax of Normal CLR Property
private int count;
public int Count
{
get
{
return count;
}
set
{
count = value;
}
}
Syntax of Dependency Property
public static DependencyProperty PageSizeProperty =
DependencyProperty.RegisterAttached("PageSize",
typeof(int), typeof(AttachedPropertySample),
new PropertyMetadata(25,
new PropertyChangedCallback(OnPageSizePropertyChanged)));
public int PageSize
{
get
{
return (int) GetValue(PageSizeProperty);
}
set
{
SetValue(PageSizeProperty, value);
}
}
In Built Change Notification
Dependency provides change notification when its value has been changed. You can specify Call Back while registering dependency property so user will get notification. This is mainly used in Data Binding. But CLR property has not any inbuilt change notification. So if you want your normal CLR proprety also notify changes, you have to implement INotifyPropertyChanged.
