responding to the model's property changes in asp.net mvc2 -

i having model not in ef, in plain text. have have updated events handled each of model's properties can log changes.

is there way achieved.

implement inotifypropertychanged interface.

a simple example:

using system.componentmodel;  public class mymodel : inotifypropertychanged {     string _myproperty;      public event propertychangedeventhandler propertychanged;      public string myproperty     {         { return _myproperty; }         set          {              _myproperty = value;             notifypropertychanged("myproperty");         }     }      public void notifypropertychanged(string info)     {         if (propertychanged != null)         {              propertychanged(this, new propertychangedeventargs(info));         }     } } 

you can use like...

public class test {     public static void main()     {         var model = new mymodel();         model.propertychanged += new propertychangedeventhandler(logchange);          model.myproperty="apples";         model.myproperty="oranges";         model.myproperty="pears";     }      public static void logchange(object sender, propertychangedeventargs args)     {         console.writeline(args.propertyname + " has changed!");         console.writeline("new value: "                     + sender.gettype().getproperty(args.propertyname)                      .getvalue(sender, null));     } }
