Because I don't know if the user wants to enter 1, 5, 10 or 100 items I
would like to add a "add Rows" Button to my page that adds 5 Rows to my
formtable.
Currenty I see two ways to accomplish this:
1) adding an ActionButton in its listener adds 5 "empty" Items to the
FormTable
This option would be the easiest to implement. In your ActionButton
event you create 5 new Items in your database (or storage of choice).
However because the ActionButton listener is fired in the onProcess
event, you would already have set the Table's rowList. So you would
need to manipulate the FormTable rowList in the ActionButton listener
in order to reflect the 5 new rows. Alternatively you could do a
redirect to the same page in the ActionButton listener which will also
refresh the FormTable and pickup the 5 new rows.
2) adding 5 Rows using Javascript
I would prefer solution 2).
Now I was wondering if the Click-FormTable would recognize that there
are more rows in the table.
FormTable is driven by its rowList so it won't recognize the new rows
or bind their values. What you can try is add a HiddenField to the
Form which tracks how many new rows were added. You can use JavaScript
to update the HiddenField every time new rows are added. In your Page
you need to check the HiddenField value and create that amount of new
Items before setting the FormTable rowList. Further if you inspect the
HTML source code you'll note that FormTable rows are indexed based.
Thus the fields in row 1 will be suffixed with "_0" and so on. You
need to increment the index when adding new rows.
Hope this helps.
kind regards
bob
