I'm trying to figure out how to run additional checks when someone tries to delete a record from a Gridview or Detailview. I already have a confirmation using Javascript, but I want to perform some validation before the record is deleted.

My application has a list of servers and a list of environments. The environments are made up of several servers. I don't want the user to be able to delete a server that is still a member of an environment - they should be forced to change that server in the environment to another one so that the server they are trying to delete is no longer attached to it.

I know how to write the SQL statements etc, I just need to know how to catch the delete event before it happens and then continue it or stop it depending on the outcome of the SQL query.

Try taking a look at the GridView.OnRowDeleting event.

Thanks. Once I searched for the event i found a good example of what I wanted to do.

For anyone else who's interested, in that event you do whatever your checks are and then if you want to stop the delete do -

e.cancel = true

to stop the delete occuring. The event occurs after delete is clicked, but before the row is deleted.
