If I have a multiple textboxes as part of a DataList or Repeater I have to create an extender for each. This produces a very slow page if I have 30 rows. We really need the ability to extend all of these textboxes with a single extender assuming it does this in an efficient way
Comments: This cannot be implemented because of ASP.NET AJAX Control Toolkit architecture limitations. If you need the CalendarExtender functionality for multiple text boxes, you can use the [jQuery UI Datepicker widget](https://jqueryui.com/datepicker/) as described in this stackoverflow thread: http://stackoverflow.com/a/10803548/644496
