IsDirty OnPropertyChanged?

IsDirty OnPropertyChanged?

Just a suggestion for inclusion to CSLA at some point.  We have styles that change based on IsNew, IsSaveable, etc - but adding a similar style for IsDirty doesn't work out well because it's missing an OnPropertyChanged.

This may have already been suggested, but if not - I think this would be helpful for WPF development purposes.

For example,

protected void MarkDirty(bool suppressEvent)


    // Add code to call OnPropertyChanged for IsDirty specifically

    this._isDirty = true; this.OnPropertyChanged("IsDirty");

    if (!suppressEvent)





Hope all is well,

Thank you for the feedback.

This has been discussed many times. The problem is that this change would conflict with Windows Forms behaviors, and a lot of people still use Windows Forms. Eventually I'm sure I'll make this change, but transition takes time.

In the meantime there are good answers for WPF users - most notably the ViewModelBase and CslaDataProvider types, along with the ObjectStatus component. All three of these are WPF components that elevate important metastate properties to a bindable level, including raising appropriate PropertyChanged events.
