Lets say we have such a CGridView widget showing a list of users for administrator. Users have status „active“ or „disabled“.
Grid widget puts class „odd“ or „even“ to rows and we want to preserve this. So we want to add a class „disabled“ to rows with disabled users.
Changing the way a CGridView is rendered from the configuration file, or through behaviors specified at the moment it is used, is handy to extend a CGridView without creating tons of different classes for it.
I am surprised that this is not in the default implementation, so I made my default CGridView implementation.
If you have to display a overview of related data in a table,
you can use the CListView, create your view with table/tr/td tags
and implement db-queries in the view to display detaildata of the current (master-)record.
Backoffice Grid Views often list information like Posts for a blog while showing at the same time linked information like the User who wrote that post.
For more efficiency, it is appropriate that the User is displayed as a link to the User detail page.
I've seen many tickets regarding how to show friendly delete confirmation using CGridView's CButtonColumn in ajax request. If you are using relational database, after producing CRUD functionality when you try to delete a record in ajax mode which has child record it can't be deleted and you can see the ajax loader forever. By this way you can't show the users if a record has been successfully deleted or if there are some problem in flash style (setFlash() / getFlash())
