Property Value

Type Description
ViewItemVisibility

A ViewItemVisibility enumeration value specifying the visibility of UI elements affected by the conditional appearance rule.

Remarks

The following UI elements can be made invisible/visible:

  • Property Editors that are inherited from the PropertyEditor class;
  • Layout Items, Layout Groups and Tabbed Layout Groups;
  • Actions;
  • Data columns in a GridListEditor, ASPxGridListEditor, TreeListEditor and ASPxTreeListEditor when the appearance rule's criterion doesn't require information on the current View's objects. So the criteria can be like "1=1" or a criteria using a Function Criteria Operator that is not based on the current object properties. This feature is considered as an unnatural scenario and described in the Conditional Appearance Module Overview topic.
Note

The Show value of the Visibility property has effect in List Views only, when it is required to unhide a column (see the Show and Hide List View Columns section of the Conditional Appearance Module Overview topic).

You can find many examples in the Declare Conditional Appearance Rules in Code topic. See these examples in the Feature Center demo installed with the eXpressApp Framework, or refer to the Feature Center demo online.
