How to use a dynamic text link as a post-back trigger?

[darrel]

I have a form that has a 'sub-form' in it that updates a separate table.

I can easily add records to this table from within this page. To delete,
though, I've been redirecting to a different 'delete' page where it asks for
confirmation before deleting. This works, but the problem is that I loose my
postback information from the main page. Since this is just a small bit of a
larger form, I don't want people to fill out half the form, get to this
point, delete an item, only to see the rest of their form reset.

So...

I decided that the confirmation isn't really that necessary for this, since
it's just a relationship I'm deleting...not the actual record. As such, I
want to delete the item from this page.

The question is how to I create these dynamic 'delete' links? Here's how I
currently do it:

(larger part of form)

item 1 | delete
item 2 | delete
item 3 | delete

these delete links are in a repeater and I build them one by one as such:

a href="deletepage.aspx?itemToDelete=[itemID]

So, I'm passing a specific field with each link to a new page.

Is there a way I can make these dynamicly rendered links (or buttons, if
need be) postback triggers? If so, how can I dynamically attach the itemID
to each one?

Darrel, I'm not highly familiar with the capabilities of the Repeater
control, so I don't know whether there is a way to easily render a
LinkButton-type control in your current approach.

However you can definately emulate this behavior in a DataGrid, which seems
more appropriate for what you're doing.

In that approach, you would have a Delete link per row, which on click would
do a postback instead of a link to another page. Since you're not leaving
the page you don't lose your view state, and you can still do the delete
operations ad-hoc.

Another approach is to programmatically render your UI using a Table and
embedding TableRow's, TableCell's, LinkButton's, etc. This is nice for
especially complex UI's but in your case I would guess that the DataGrid is
the best solution.
