paging : Paging

Paging determines the paging behavior of 'list' UI controls.

Paging affects any control that presents lists and has an <a href="#orderBy">orderBy</a> property. An Order By attribute must have a unique index defined in the persistence mapping/schema to be used in paging. This means that each attribute bound to sortable columns in a 'pageable' grid must be indexed. If not, all rows will be retrieved to the client for sorting.

Valid values based on“string”.
auto	The model determines the best paging type to use. The model looks at the Order By property of the UI control. If there is a unique index defined in the schema that starts with the attribute(s) listed in the Order By property, bookmark paging will be used. If there is a non-unique index defined in the schema that starts with the attribute(s) listed in the Order By property, offset paging will be used. If the Order By has no index, none-sortserver paging will be used. Enumeration value is 0.
bookmark	The model can use bookmark paging.
offset	The model can use offset paging.
none-sortclient	The model will have no paging and a sort on the server.
none-sortserver	The model will have no paging and a sort on the client.

promptOnDelete : boolean

query : string

List of additional attributes to include in read query.

required : string

The attribute, association path, or a constant returning boolean to set whether the value for the control is required.

If the attribute is required in the model, it takes precedence and one cannot change this setting in the UI. If the attribute is not required in the model, the requiredness can be set to an attribute, association path, or a constant returning boolean. If the value is set to #t, or the attribute value is true, the requiredness cannot be changed using 'required' view property that is set via client-side API. If the value is left blank, it is set to #f, or the attribute value is false, the requiredness can be changed using 'required' view property that is set via client-side API.
