Form field extension for a text box.AllowInputEmptyMultipleValues

AllowInputEmptyMultipleValues

Usage

Read and write.

Description

Type: Boolean. Defines whether empty multiple values can be entered. Default value: False.

• True. Empty multiple values can be entered interactively:
  • The "Add empty value" context menu item is added.
  • The OpenButton property is set to True.
  • The "Add empty value" context menu item is shown as unavailable if an empty value of the selected type already exists in the list (collection) or if the selected type does not have an empty value.
• False: Empty multiple values cannot be entered interactively:
  • Empty values added interactively are ignored. The check for empty values is performed after calling the MultipleValuesAdd handler and before adding a value. If the check fails, the user is shown a notification with the text: "Cannot add an empty value".

The restriction on empty multiple value entry is also applied to the standard dialog box for editing the value list if the input field contains data of the ValueList type. To open the dialog box, click "Open" or press Ctrl+Shift+F4.
