# Multi-Line Control

Extended Class Browse |

Extended Class Browse is used in the NOMADS Panel Designer when creating display-only Multi-Line controls for Extended Class Validation data elements.

#### Note:
To use Extended Class Browse, a Multi-Line control with an Extended Validation data class must exist on the current panel; otherwise, a message will display and Extended Class Browse will not be available.
At any time, a panel can have multiple Multi-Line controls with Extended Validation data classes.

To access Extended Class Browse, select the Browse Extended Class Variables button next to the Name property in Multi-Line Properties.

(Extended Class Browse was added in PxPlus 2019.)

The Extended Class Browse window consists of the following:

Control | Click the drop-down arrow for a list of Multi-Line controls (on the current panel) that have an Extended Validation data class with a Descriptive Field selected.
Class | Displays the name of the Extended Validation data class for the selected Multi-Line control.
Table | Displays the name and description of the table used when defining Extended Validation for the data class.
Variables Available | A list box that displays all data elements in the table only when the Descriptive Field is specified and the Populate All Fields check box is selected for the Extended Validation data class.
Descriptive Field is specified Populate All Fields is "On" | Displays All Data Elements
If only the Descriptive Field is specified and the Populate All Fields check box is Off, only the Descriptive Field data element will be displayed.
Descriptive Field is specified Populate All Fields is "Off" | Displays Data Element for Descriptive Field Only
Select | (Available when a Data Element in the list box is selected) When selected, the Variable name of the data element (Variable column of the Variables Available list box) is used for the Name of the Multi-Line control. The following Multi-Line attributes (on Attributes tab) are set to On: Locked, Borderless and Transparent. The Tab Stop attribute is set to Off. The Numeric attribute is set according to the data dictionary, and if Numeric is On, the Input Format (on Display tab) is set according to the data dictionary.
Cancel | Closes Extended Class Browse with no further action taken.
