DataView for objects: Implementation Part IV
Note: You can download the complete implementation here. In my last post I described the implementation of the IList interface in ObjectListView, my implementation of a view for collections of arbitrary objects. The goal is to provide the same view capabilities for collections that DataView supports for DataTables. In this post, we'll move on to the next interface required for data binding, IBindingList. IBindingList This interface ...

In my last post I described the implementation of the ICollection interface in ObjectListView, my implementation of a view for collections of arbitrary objects. The goal is to provide the same view capabilities for collections that DataView supports for DataTables. In this post, we'll move on to the next interface required for data binding, IList. Positional list access The ...

DataView for objects: Implementation Part I
In my last post, I described the .NET Framework support for views of collections of arbitrary objects. In short, the required interfaces are provided, but no implementations. In this post I'll describe what we need to do to roll our own view. In a nutshell, we need a view class that implements IBindingListView to wrap our collection of objects. Our view will provide sorting and filtering, and neither of these operations will change the ...
DataView for objects: What’s in the box
In my previous post I made the case for having a DataView-style construct for collections of arbitrary objects. In this post, I'll review what you can (and can't) do to achieve this with the built-in .NET 2.0 Framework classes. View vs. Collection First, why use a "view" rather than just a collection? For the same reason we would use a DataView rather than a DataTable. Let's say we want to present some customer data in a DataGridView ...
