CSLA.Net for Silverlight 3.6.0 (Beta 2a) - InvokeMethod.cs - Refresh()

damaq posted on Saturday, November 15, 2008

I changed the InvokeMethod.cs so that the "CanXYZ" validation links to a property instead of a method of my custom class. (The CslaDataProvider uses properties too.)

    private void Refresh()
    {
      if (_target != null && _element != null && _contentControl != null)
      {
        if ((bool)_element.GetValue(ManualEnableControlProperty) == false)
        {
          if (_target is CslaDataProvider)
          {
            CslaDataProvider targetProvider = _target as CslaDataProvider;
            if (_element.GetValue(MethodNameProperty).ToString() == "Save")
              _contentControl.IsEnabled = targetProvider.CanSave;
            if (_element.GetValue(MethodNameProperty).ToString() == "Cancel")
              _contentControl.IsEnabled = targetProvider.CanCancel;
            if (_element.GetValue(MethodNameProperty).ToString() == "Create")
              _contentControl.IsEnabled = targetProvider.CanCreate;
            if (_element.GetValue(MethodNameProperty).ToString() == "Fetch")
              _contentControl.IsEnabled = targetProvider.CanFetch;
            if (_element.GetValue(MethodNameProperty).ToString() == "Delete")
              _contentControl.IsEnabled = targetProvider.CanDelete;
            if (_element.GetValue(MethodNameProperty).ToString() == "RemoveItem")
              _contentControl.IsEnabled = targetProvider.CanRemoveItem;
            if (_element.GetValue(MethodNameProperty).ToString() == "AddNewItem")
              _contentControl.IsEnabled = targetProvider.CanAddNewItem;
          }
          else
          {
            if (_element.GetValue(MethodNameProperty) != null)
            {
              string targetMethodName = (string)_element.GetValue(MethodNameProperty);
              string canMethodName = "Can" + targetMethodName;
              //object returnValue = Csla.Reflection.MethodCaller.CallMethodIfImplemented(_target, canMethodName, null);
              System.Reflection.PropertyInfo propertyInfo = Csla.Reflection.MethodCaller.GetProperty(_target.GetType(), canMethodName);
              object returnValue = Csla.Reflection.MethodCaller.GetPropertyValue(_target, propertyInfo);
              if (returnValue != null && returnValue is bool && (bool)returnValue == true)
                _contentControl.IsEnabled = true;
              else
                _contentControl.IsEnabled = false;
            }
          }
        }
      }
    }
