    • Re: OnPropertyChanged and maintaining a list of Dirty Properties

      I converted the above into C#, but it doesn't want to compile. Are there changes available in 3.8 that aren't in 3.7 that would keep it from compiling? VB.Net: Public Shared ReadOnly DirtyPropertiesProperty As PropertyInfo ( Of Collection ( Of String )) = RegisterProperty( Of Collection ( Of...

    • Re: Broken Rule for 1 property

      By "Win8" do you mean WinRT? Some features of the WinRT runtime are more similar to Silverlight 2 than to modern XAML. As a result the PropertyInfo control uses the SL2 binding scheme because the modern binding scheme can't be implemented :( <csla:PropertyInfo Name="blah" Source...

    • PropertyInfo Control in CaliburnMicro

      Does anyone have an example of a Style for a TextBox using the PropertyInfo Control with CaliburnMicro? I have been trying to cobble something together based on the WP example but have had absolutely no success. I get the impression that the DataTriggers aren't firing but I have no idea what I am...

    • Re: PropertyInfo & WinRT

      WinRT is missing some features used by the 'modern' PropertyInfo control in WPF/SL. The WinRT version of PropertyInfo uses an implementation more similar to what we did for Silverlight 2.0, which was also missing these features. As a result, the Property property can't be a binding expression...

    • PropertyInfo & WinRT

      I'm trying to use the PropertyInfo control in a WinRT app, and I can't get the binding to work correctly. I want to bind another control's appearance to the IsValid meta data for a BO property that the PropertyInfo control exposes. The problem is that the binding is triggered only once when...

    • Re: Xaml.PropertyInfo

      Although it is relatively complex, most of the WPF/SL samples now use a style (defined in App.xaml) for the TextBox control that relies on the PropertyInfo control to do its work. The style gets its information from PropertyInfo and uses that information to control the appearance of the TextBox control...

    • Subclassed PropertyInfo, Custom PropertyInfoFactory, and RegisterProperty using Lambda

      Hello, I have implemented MyPropertyInfo<T> derived from PropertyInfo<T> and a custom PropertyInfoFactory which returns my derived type. My BO declaration however uses the lambda RegisterProperty overload and is declared as PropertyInfo<T>, not my subclassed type private static PropertyInfo...

    • Read-only Calculated Property

      Given a business object called “Rectangle” consisting of three integer properties “Width”, “Height” and a read-only “Area”. Would you make the read-only “Area” property a full blown PropertyInfo property? If so, you would need to create a rule...

    • Re: PropertyStatus and object level rules

      You are thinking of putting a PropertyStatus control on a form, and not specifying a property for the control, so it would know to pick up object level broken rules? This wouldn't be terribly hard to do, but I wonder about the visual representation? Where would you have the error icon appear? And...

    • Why isn't PropertyInfoManager contained within BusinessBase similar to how FieldManager is?

      I know that FieldManager is exposed as a protected property within BusinessBase. Why isn't PropertyInfoManager setup the same way? From what I can gather, PropertyInfoManger maintains a dictionary of Types and a list of each Type’s PropertyInfo(s). It would seem easier to just have a list of...

    • CSLA 4.1.0 - RegisterProperty on ReadOnlyBase has no overload to set RelationshipTypes

      I've started our mainline transition to CSLA 4.0 (which includes our own in-house code generation using a DSL Language). I've added support for the new RelationshipTypes parameter used by some of the RegisterProperty overloads and it works great! However, I ran into an issue when using a private...

    • LoadProperty and ReadProperty in CSLA 4

      i was just going over the ProjectTracker examples from 4.0.1 vs my older 3.6.2 and i was wondering why all of the dataportal methods only use LoadProperty and ReadProperty for SmartDate fields and not on all properties when they are being set or retrieved? wouldn't you want to bypass all the authorization...

    • MVVM - Possible to use Lambda expression for stronly named method name in ViewModel.BeginRefresh(...) method?

      Hi Rocky I'm going through the MVVM video series and it occurred to me that it would be very nice if the ViewModel.BeginRefresh( string methodName ) method was capable of using a "non-magic string" syntax like like we do with the RegisterProperty convention? The RegisterProperty scenario...

    • Type Initializer error using PropertyInfo

      I have been using CSLA 3.8.2 w/VB in a new application. I had been using syntax from CSLA 2.0 for properties and decided to switch to the new PropertyInfo method. I rewrote a lot of code, but when I tried running it I received the error {"The type initializer for 'EPM.Library.OwnerBase'...

    • Re: RegisterProperty for derived classes in 4.0

      When creating an abstract base type, that type must be generic. Or you can't use the generic overloads of RegisterProperty() - the choice is yours. Obviously the type T is frozen at the point where your types become non-generic - that's the way generics work. Using things like stack traces and...
