If you are using gridview, you will have the deleteitemtemplate in which you can specify the command type as a button or a link. So when you are selecting the row for edit, it will display the command there.

Hi there,

Good to hear you like the book so much.

If you want to know how to do it exactly, take a look at appendix A which has all the answers to the exercises.

Cheers,

But did you manage to make it work and complete the task?

it works ya, but i'm im wondering, can't i get same result without the code behind: i.e. by 1. having a button with CommandName Delete and 2. enabling Delete on the dataEntity source object?!

thanks

Yes you can, but that only deletes the database record and not the file on disk which is what the exercise is about.....

Cheers,
