    • Csla.NameValueListBase<K,V> for Windows Forms or safe for WPF

      Hi Context: Given that BusinessBindingListBase<T,C> is for supporting Windows Forms under CSLA 4, and BusinessListBase<T,C> is the Xaml (ObservableCollection) equivalent, then what about NameValueListBase<K,V> ? It is derived from the Csla.Core.ExtendedBindingListBase<T> type...

    • CanExecuteRemove not working in CslaDataProviderCommandManager in CSLA 4.5

      I updated a fairly old project to use CSLA 4.5, and suddenly noticed that my Delete buttons linked to the CommandManager of the CslaDataProdiver were not getting enabled when they should. After downloading the source code and looking at the process in question I realized that the cast in the CanExecuteRemove...

    • TriggerAction customization

      Two questions relating to the TriggerAction control and the XAML around it. First, I've read Rocky's blog post here about the control. My questions are: 1. Does the TriggerEvent attribute absolutely have to be in the format public void MyAction(object sender, ExecuteEventArgs e) or can it be...

    • Re: Windows 8 and NotifyOnValidationError

      One solution is to use the Csla.Xaml.PropertyInfo control as a data source to get at the metastate and other data about a property. Then you can bind other UI elements to that PropertyInfo control, like a tooltip, or red Rectangle or whatever you'd like.

    • Re: Anyone here have any *solid* plans to write WinRT apps using CSLA?

      I assume by "writing native WinRT apps using CSLA" you mean C#/VB, XAML and CSLA, correct? Not just CSLA alone? I can think of a couple of reasons to continue to build upon these skills. Among them, it provides a relatively easy path into the WinRT development world using what you already know...

    • Re: Silverlight: ReadOnlyList Recommendation

      That's exactly what I do. Frequently I find that a CVS resource can index into properties of my "root" model object or viewmodel in ways that you can't do with a binding expression. And I don't mind that, because the CVS adds sorting and that sort of thing, so it is generally a...

    • CslaDataProvider differences between WPF & Silverlight

      I just spent many hours trying to figure out why data binding was working in a (CSLA) WPF app, but the same data binding failed (at runtime) in a (CSLA) Silverlight app. There is a subtle difference that I couldn't find documented anywhere that I will document here for other people to hopefully find...

    • Debugging WCF Service for a CSLA Silverlight app

      I have downloaded the CSLA source (latest version) and I can debug through the SimpleApp sample on the Silverlight side, but I can't get the debugger to break in the WcfPortal code or the CustomerEdit DataPortal_Insert() method.

      Hello Does the TriggerAction require the custom controls to be derived from FrameworkElement? I'm using a custom control that derives from FrameworkContentElement and I can't get the Trigger to work on the element's click Event. If that's the case, what work around can anyone recommend...

    • Re: "Add New Data Source" - where's my ViewModel?

      The VS designer will actually instantiate the type as you do drag-and-drop. So if there's something blocking the type from instantiating (like it tries to talk to the database when in design mode) that'd cause this issue.
