postback resetting checkbox state

[Chris]

I've got a gridview with a column of checkboxes. If I check off any
number of them, and perform a postback, they all go back to being
unchecked. What options do I have for getting around this?

Don't rebind the data in Page_Load every time. Use, for example, a If Not
Page.IsPostBack Then and only bind then. The viewstate is reconstituted
prior to Page_Load, so you will overwrite every time if you bind there.

Interesting, it seems that system.web.ui.webcontrols.button is the
culprit. If I put a 'select' control link in my gridview, that keeps
the checkboxes just fine. I wonder what the difference is?
