问题 I created my own control and overwritten the onpaint event, the problem is that the paint event stopped working Any ideas why?

问题 Interesting. I have a control QuickContacts with Contacts collection. When I declare Contacts of type List<Contact> it works perfectly, but when use ContactsList<Contact> which is a Generic that implements IList<T> it gives "Parser Error : Type 'Controls.ContactList'1[[Controls.Contact, Controls, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null]]' does not have a public property named 'Contact'."
