Storing a collection into a list and session - Front End

I have this program in which I am trying to store a collection of values into a list and session

Example:

valueCollection = (List<Values>)Session["Value"];

I want to do the front end in a way which will show a table with each row showing a label and textbox. This would be too simple to do obviously but I want it to show 4 rows of the table by default and then the user can select 开发者_运维百科"add another" this will then add another row onto the table with a label and textbox exactly similar to the 4 default. Everytime the user selects "add another" the table increments by 1.

How do you do something like that, or is there an easy way?

Here is a screenshot to explain it better: http://img828.imageshack.us/img828/9986/idead.png

The basic idea is that you bind a control to your data and provide GUI controls to allow users to add/edit/delete records. Once the records are modified you re-bind the control to see the changes.

Take a look at the Databound controls in the .Net Framework. For a quick first pass you could use a ListView - a control which provides built-in functionality to automatically generate and mange the add/edit/delete GUI elements.

In 'real world' usage, storing big datasets isn't a great idea as more users = more sessions and each session uses server resources. You should really be getting/storing your data in a database or perhaps an XML file.
