Data Viewer

The Data Viewer displays the Attributes of a single Entity.

Control properties

• Prefix key - Unique identifier of the Form Control. This does not link the Form Control to an Attribute, but it is required to access the Attributes displayed in this Form Control by other Form Controls. Form Control Expressions of Form Controls can access the displayed Attributes by using the Prefix key, followed by an underscore (_) and the name of the Attribute. For example, when the Prefix key is MyViewer and the Attribute is MyAttribute, then the Attribute can be accessed by $MyViewer_MyAttribute.
• Hide control? - Hides (Yes) or shows (No) the Form Control in the Form. Be aware that the content of hidden Form Controls is stored by Save and Sign and Save Actions in the linked Attribute.
• Condition type - Allows you to hide the Form Control based on a Form Control Expression evaluating to true or false:
  • Display condition - Hides the Form Control when the Form Control Expression evaluates to false and shows it when the Form Control Expression evaluates to true.
• Source - The Entities of this Entity Type are loaded into the Form Control.
• Id value / field - The Attributes of the Entity with this Id will be shown by the Form Control. The Id can be entered directly or calculated by a Form Control Expression, but is must be a single and unique Id. The Entity is loaded automatically by this Form Control from the Database. Hence, it is not required to load the Entity by a Load Activity.
• Attributes - Controls which Attributes of the Entity are shown. If no Attributes are configured here, nothing is shown.
  • Add attribute - Adds an Attribute
  • Label - Label displayed over the value of the Attribute identifying it to the Users.
  • Attribute - Name of the Attribute to be shown
  • - Remove the Attribute
