    • Re: Edit Level mismatch error

      Windows Forms data binding is very particular about following its rules. And so is CSLA. The rules are relatively straightforward, but you can't deviate. The primary rule: every beginedit must have a corresponding canceledit/endedit on each object (parent, child, etc). Edit level mismatch occurs...

    • Re: BusinessListBase vs BusinessBindingListBase

      [quote user="Tiago Freitas Leal"] Besides sharing the experience, I think this also raises a point. If we must use BusinessBindingListBase for Windows Forms and BusinessListBase for WPF/Silverlight, suppose my application has both clients. I need to have duplicated Business*ListBase classes...

    • Two BindingSources with the Same DataSource Type

    • Problems with Begin- / Cancel- / Apply-Edit operations

      Hello community! I'm lost with the undo capabilities of CSLA. I have found several questions/answers dealing with the strange behavior of data binding under windows forms. But alas, I'm not using data binding at all in my test application. I'm using CSLA 3.8.4, C#, .NET 3.5SP1, VS2010, NHibernate...

      Jonny is right, but it sounds like you've already dug into the Using CSLA .NET 3.0 ebook in some depth and probably have the basic concept. If you want a top-level Cancel button, you need to manually call BeginEdit on the root object before you bind it to the UI . And then you need to unbind the...

    • Re: Help with Save and Update in Winforms MDI App

      The best and most detailed information on dealing with Windows Forms is in the Using CSLA .NET 3.0 ebook - there's a chapter on the topic in that ebook.
