RowRepeater 

A RowRepeater is used to display UI elements specified in the Element (ROW_ELEMENTS) aggregation in a list. Each row in a RowRepeater looks the same since each row consists of the same UI elements, and only the individual rows contain different content.

A RowRepeater is bound to the dataSource of multiple context nodes. For each element in the context, a row is displayed in the RowRepeater.

The ROW_ELEMENTS define the structure of a row in the list.If the element is a TransparentContainer with MatrixLayout, the matrix data is assigned in the grids of the RowRepeater. You can use the vGutter property of the matrix data to attain additional padding and display vertical separators. Otherwise standard values are used for the layout properties.

The accessibility of the RowRepeater can only be ensured if the RowElements, as mentioned above, are TransparentContainers with a MatrixLayout in which no other container type UI elements (TransparentContainer, Tray, Group, and so on) are nested.

Furthermore, accessibility is only possible if a meaningful rowDescription has been created.

The RowRepeater is recommended for layouts that are repeated vertically. For example, the shopping basket shown below.

You should use the Table UI element for single-line tabular data.

The use of the Table UI element in the TablePopin and RowRepeater UI elements is not supported.

Within a RowRepeater, complex UI elements such as Table, Tree, GAC*, ViewContiner, InteractiveForm, Gantt, Network, Group, and Tray are not supported.

Aggregations in the View Designer

Name	Cardinality	Type
Element	0..n	UIElement

Other properties that can be inherited are defined in the associated higher-level classes. The associated UI elements are:

●        UIElement

●        ContextMenuProvider

●        ViewElement

Dynamic Programming

For dynamic programming, the same properties, events, and aggregations as in the View Designer are available. Bear in mind the different spellings.
