Let’s imagine we have a huge collection of some objects (may be our data objects) and we need to filter this collection and display only a part of its elements in different places in our WPF application. Instead of creating many different instances of sub collection we can use the benefits of collection views.
In a previous post I have described hot to utilize a INotifyDataErrorInfo interface. Today I will show you my solution for automated cross-property validation integrated with the ModelValidation base class from previous post.
Recently we moved our main WPF project to .net framework 4.5 and Visual Studio 2012. Then when I tried to preview some of basic views in Visual Studio designer I faced some strange problems. We have several user controls that we use in our views.
