Displays a WEBDEV page as a popup in the current page with a DDW (Dim Disabled Windows) effect. This function is used to easily simulate a dialog box in browser code.
Remark: To display a Popup page, PopupDisplayPage can be used:
  • in the code of a Button control with the option "Run browser click code only". In this case, only the browser code of the Button control will be executed.
  • in a Button control with the option "Run server and browser codes" (that sends values to the server). AJAX must be enabled in the code of this Button control. In this case, the browser code and server codes of the control will be executed.
Example
// Displays PAGE_ProductDetails as popup
PopupDisplayPage(PAGE_ProductDetails, (nProductID), popupCenter)
WEBDEV - Browser code
// Displays PAGE_ProductDetails as popup
// Waits for the page to close and displays the returned value
PopupDisplayPage(PAGE_Details, (nProductID), PopupDisplay_Callback, BTN_CONTROL, popupPositionXY, 10, 10)

	INTERNAL PROCEDURE PopupDisplay_Callback(ReturnPopupPage)
		Trace("The popup returned: [%ReturnPopupPage%]")
	END

  • It is not possible to open two popup pages at the same time using PopupDisplayPage.
  • The DDW feature can be disabled and customized in the code, using PageEnableDDW and PageRateDDW.
  • WEBDEV - Server code This function cannot be used in the scheduled tasks and in the delayed tasks. For more details, see Scheduled and delayed tasks.
  • The AJAX processes of the page displayed by PopupDisplayPage can update only the controls in this same page. To update the contents of the controls in the page that calls PopupDisplayPage, you can:
    1. create a browser procedure in the page that calls PopupDisplayPage. The procedure will take the new data as parameters, and will assign that data to the controls in the page.
