Are there any 3rd part WinForms controls out there that give me ajax type effects. For example I want an effect where if I have a list box or a DataGrid control and someone clicks a field to mark it as complete I want that field to fade away not just instantly disappear. The standard controls get the job done but are not the best looking.
I hope that came accross clear.
Have a look at WPF (Windows Presentation Foundation). This is Microsoft's new framework for developing graphically rich user interfaces, and would in fact be capable of a lot fancier effects than you see with AJAX.
WPF is a radically different technology to its predecessor WinForms, but it's well worth the time spent learning!
There are pleny of third party controls..
