WPF, BusinessListBase, filter

Hi there

What is the recommended way of filtering a databound businesslistbase collection in WPF?

Use either a LINQ query or FilteredBindingList. Probably a LINQ query though, as FilteredBindingList is more geared toward Windows Forms.

var filtered = from r in _mylist where r.SalesTotal > 1000 select r;

Assuming _mylist is a BLB, you'll get back a LinqBindingList, which is a synchronized view over the original list, and you can bind that to your UI.
