I have an ASP.Net page. Code is C#. The page displays 2 listboxes side-by-side. The first listbox displays data from a table in a database (MS Access). It lists all available products. The second list box displays all of the products that the user has selected. The second listbox's data will come from another table. Once a user selects a product and clicks the correct button, the product is moved to the seond listbox. I need to display the correct data in that second listbox based on the users login information. That second table will record product id and user id. The second listbox also needs the funtionality to move products up and down in rankings. Any help/samples with this is appreciated.

Sorry, I worded this horribly. My question is how I can move records up and down in the second list box. I have the functionality to display the data in each listbox, and move a record into the second box fromm the first. I want the user to be able to move the records up and down( they are ranking them). Does that make any more sense?

If you are binding a ListBox to a DataTable, and you want to control the order of the items in the ListBox, then I would suggest adding an Integer sorting column to the DataTable, creating a DataView from the DataTable, and then bind the ListBox to the DataView, with the Sort property set to the sorting column.
