• WPF ListView as a DataGrid – Part 3

  - by psheriff

  I have had a lot of great feedback on the blog post about turning the ListView into a DataGrid by creating GridViewColumn objects on the fly. So, in the last 2 parts, I showed a couple of different methods for accomplishing this.

  - by Adam S

  Hi all, I'm trying to write a class that I can use to interact with a group of similar controls in my wpf application.

• WPF - Why doesn't Microsoft supply a decent set of most-used controls ?

  - by IUsedToBeAPygmy

  I've been playing with WPF for some months now, and I quite like it. But one of the things I don't get is why MS doesn't put a little more effort in helping developers by supplying basic controls, and I need to get this off my chest :) For example, I figure most applications somewhere will need to let you edit some properties - for…

  - by CraigJ

  I have a large VB6 desktop app which I would like to upgrade to .NET in order to take advantage of the newer .NET API.
