Enable the Popup Template OK and Cancel Button Bar
You can show the OK and Cancel button bar instead of the standard OK and Cancel buttons on a Popup template. The button bar keeps the OK and Cancel buttons visible when the template is scrolled at run time.
You can map the OK and Cancel buttons on the bar to the original OK and Cancel buttons or to other buttons on the Popup template to execute the trigger from the button it is mapped to.
You can place the OK and Cancel button bar on any Popup template type. You can display both a navigation bar and the OK and Cancel button bar on the same Popup template.
