I have a web part page that the user is interacting with. On there in some type of webpart, I need to have the user enter a valid date / select from a date widget. The date needs to be converted to ISO 8601 format and fed to the CAML filter of a chart (to show data from between the two dates) and a ListView (to show line item data between the two dates). As i mentioned above, I have used a qselector to show the user a dropdown list that is then passed by session variables to the CAML filter. In this case, the qSelector will not work since not all possible dates can be stored in the list.
