Click and drag selection box in WPF

Question

Is it possible to implement mouse click and drag selection box in WPF. Should it be done through simply drawing a rectangle, calculating coordinates of its points and evalua

Answer 1

This project created a custom MultiSelector which supports several selection methods including a rectangular "lasso" style:

It is far too long to reproduce here. The key elements of the design, IIRC, were to create a custom ItemContainer which knows how to interact with its MultiSelector parent. This is analagous to ListBoxItem / ListBox.

This is probably not the simplest possible approach, however if you are already using some type of ItemsControl to host the items which may need to be selected, it could fit into that design pretty easily.
