>>Clicking the Edit hyperlink will also cause a postback. The common cause of a Datagrid not being rendered is that the Datasource is not assigned or has no data. Check to see if the Datagrid is bound to the Datasource when the Edit postback occurs - it should not be unless you are also caching the Datasource and reloading it before the bind.

Rick,

To use different controls for editing, you will have to build up the Datagrid with Template columns rather than using the automatically generated columns.

There is a wealth of articles and help topics about templated Datagrids. A nice place to start might be http://aspnet.4guysfromrolla.com/articles/040502-1.aspx.
