We have a series of drop down controls that determine the sort order of columns. The problem we are having is when the user selects a column as the 2nd column the other dropdown lists need to have their values changed so that there is only one ‘2nd’.

  1. Column A [1]
  2. Column B [2]
  3. Column C [3]
  4. Column D [4]
  5. Column E [5]

In the list above, when you change Column D to [2], Column B becomes [3], C becomes [4], etc. I can manage it on the server side but I was wondering if anybody had some clues how to do this on the client side with javascript.

  1. Look at Javascript toolkits like Scriptaculous for client side reordering.

    You add your elements as ‘Sortables‘ and code your own callbacks to execute when the items are dragged, then dropped — such as sending an asynchronous request to the server to persist the new order.

    Here is a full tutorial on creating sortable lists with Scriptaculous and PHP. For ASP, the client side code will be slightly different, but the process will be similar.
