GridView: show date

[shapper]

Hello,

I have created a GridView on runtime by implementing the ITemplate
class.

This Gridview displays a list of articles. Each article has a Title,
Content and PubDate.

I am trying to create a Date Header like in a blog, i.e., display the
date on top of every daily posts.

For example:

Wednesday, 25 of April of 2007

Article 3 (PubDate: 25.04.2007 # 20:15)

Article 2 (PubDate: 25.04.2007 # 11:30)

Article 1 (PubDate: 25.04.2007 # 08:40)

Wednesday, 24 of April of 2007

Article 2 (PubDate: 24.04.2007 # 21:32)

Article 1 (PubDate: 24.04.2007 # 15:45)

How can I created the date header as I described?

Thanks,

Miguel
