Sometimes you might need to process more than one MouseHover event, for example if you have a user control which has draws shapes on itself. As long as you have a record of where the shapes are (by storing them in a collection), you can use the method below as a workaround.I used th<img src ="http://blog.csdn.net/fan178/aggbug/3932229.aspx" width = "1" height = "1" />Tue, 24 Feb 2009 22:43:00 +0800fan178http://blog.csdn.net/fan178/archive/2009/02/24/3932229.aspx#Feedbackhttp://blog.csdn.net/fan178/archive/2009/02/24/3932229.aspxfan178http://blog.csdn.net/fan178/archive/2008/09/06/2892759.aspxhttp://blog.csdn.net/fan178/comments/2892759.aspx1http://blog.csdn.net/fan178/comments/commentRss/2892759.aspxhttp://tb.blog.csdn.net/TrackBack.aspx?PostId=2892759This afternoon, I took part in  Improvisational theatre class.

I found there is no ColorDialog in wpf application, and toolbar also doesn't work, I cann't add items, the add button is disable, I think maybe I should add ItemsSource first, it implement IEnmerable. When I fix that I will write detail resolution.
