Remarks
A LayoutViewCard object represents a card in a LayoutView View and specifies the layout of fields within a card. All cards in a LayoutView have the same layout, as specified by the LayoutView.TemplateCard property.
To customize the layout of fields within a LayoutView‘s card, create and customize a LayoutViewCard object and assign it to the LayoutView.TemplateCard property.
A LayoutViewCard object consists of items, derived from the BaseLayoutItem class. The following items are available:
- LayoutViewField, representing a data field, displays an edit box with an optional text label.
- LayoutControlGroup combines other layout items into a group, like the GroupControl control.
- EmptySpaceItem - represents an empty region. You can use it to add empty space to a card.

Example
The following example shows how to create and customize a Layout View in code. In the example, a template card is created, consisting of six fields arranged as in the image below:
Before arranging layout fields in code, ensure that corresponding columns are visible (see LayoutViewColumn.Visible and GridColumnCollection.AddVisible).
