c# - Catel framework - Lazy property -


i'm trying create lazy property catel framework. there way it?

when i'm creating property in viewmodel this:

#region photos property  /// <summary> /// gets or sets photos value. /// </summary> public fastobservablecollection<photo> photos {         {         var temp = getvalue<fastobservablecollection<photo>>(photosproperty);         if (temp == null)             photos = selectedpatient.getphotos();         return getvalue<fastobservablecollection<photo>>(photosproperty);     }     set { setvalue(photosproperty, value); } }  /// <summary> /// photos property data. /// </summary> public static readonly propertydata photosproperty = registerproperty("photos", typeof (fastobservablecollection<photo>));  #endregion

the get function called without binding, lazy property initializes while viewmodel initializing.

is there way it?

there 1 way implement "lazy properties", , using lazy<> class. reason mappings (such view model model, etc), catel uses setvalue directly instead of property wrapper (compare catel properties dependency properties).
