title: asp.net: 2 column listbox with option to edit
body: <p>I have an asp.net web application. the listbox has a data source of one field. it has 10 items. i want the user to be able to add a comment for every (or for specific) items. so i would like a listbox or combobox with 2 fields. one field will be the list of items and the other field will be blank and will allow user input. </p>
  
  <p>does such a control already exist? the solution can be c#, asp.net, jquery. </p>
  
  <p>i understand that this can be done with gridview, but can you please tell me how i can make one field read only and the other field editable?</p>
