For my site's admin panel, i am displaying a big table of all of our media files pulled from a SQL database. Next to each one, I am creating a few buttons such as "Edit" "Delete" etc. All these are created dynamically on page load, and attached to a placeholder.

I am having some problem with handling the input, however. I am using:

Dim myButton as Button = newButton
AddHandler myButton.OnClick, AddressOf Somefunction
somePlaceholder.Controls.Add( myButton )

However, this only works if I re-create the buttons each pageload. What I wanted to do is create the list of media only when we are not in postback, and when a user clicks the "edit" button it refreshes the page and creates an Edit dialogue, without the list being re-generated. However, if I do not re-create the button in postback, the handler never gets called (which makes sense).

How can I dynamically create buttons that will execture functions on post back (and pass in a parameter, such as an ID of the media we are supposed to edit)? Do I need to create a new form for every single entry in my list, with hidden input elements that store a command and parameter I parse on postback? Or is there a better way?
