Trouver les DependencyProperty d'un control

Bonjour vous tous...

J’espère être au bon endroit pour poser ce type de question :

Voilà je cherche à énumérer les DependencyProperty de n’import quel DependencyObject via une methode ex :

Public List< DependencyProperty> GetDependencyPropertys(DependencyObject element)
{
// ??
}

ou
Public List< DependencyProperty> GetDependencyPropertys(Type element)
{
// ??
}

Une idée ??

Salut,

Voici un post qui en parle :
http://social.msdn.microsoft.com/For...-3e3ba118c89c/

Il en arrive à la fonction suivante (j'ai pas testé) :

Code:

---

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

public IList<DependencyProperty> GetAttachedProperties(DependencyObject obj) { List<DependencyProperty> attached = new List<DependencyProperty>();   foreach (System.ComponentModel.PropertyDescriptor pd in System.ComponentModel.TypeDescriptor.GetProperties(obj, new Attribute[] { new System.ComponentModel.PropertyFilterAttribute(System.ComponentModel.PropertyFilterOptions.All) })) { System.ComponentModel.DependencyPropertyDescriptor dpd = System.ComponentModel.DependencyPropertyDescriptor.FromProperty(pd);   if (dpd != null && dpd.IsAttached) { attached.Add(dpd.DependencyProperty); } }   return attached; }

Sinon, avec la reflection, tu devrais y arriver mais cette solution semble plus optimisée

public abstract class BigThanks<T> where T ::king:

L'obectif du départ étant de pouvoir lister les DependencyProperty pour un DependencyObject donné.
De ce fait, nous ne souhaitons pas de propriété jointe (dpd.IsAttached =false)...

if (pd.ComponentType == ComponentType)
{

if (dpd != null && !dpd.IsAttached)
{

DependencyPropertysResult.Add(dpd.DependencyProperty);

}

}


Voilà mon petit code pour RoutedEvent et DependencyProperty:
Les methodes avec "All" retourn également les DependencyProperty ou RoutedEvent des classes parentes. Sinon uniquement les elemenents de la classe elle même.

Code:
