Summary
The Pop-up Selections Screen displays a list of options to the user for selection. It is very common on AS400 systems and is typically displayed by pressing the F4 key while in an entry field supporting this functionality (Common User Access Display Selections key).
Roles
| Host | For fields that have a backing database or option list in the host, providing a pop-up selections screen is the best way to help users enter a value they may not know completely. For example, a Customer Number field can provide a popup Self-Contained Search for Customer Number based on Last Name, so that a user can press the F4 key in the Customer Number field, find the customer, select the customer and have the customer number "poked" into the entry field. |
| UI | For the right UI implementation, the Popup Selection Window must be recognized and mapped as a Popup Screen. Then, the TextEntryCustom Web Control has the "SelectionPopup" property set to true, which will display a clickable icon next to the Entry Field. When the Icon is clicked, the Popup screen will be displayed as a true popup. As defined, the data can be poked back into the field on the web page, or entered at the server (host) end so that if other fields on the screen are updated by the selection, they will be reflected in the Web Page. |
Here is an example of a Popup to select a Company from a simple list (no search field provided).
