Property Value

When a grid is in a card-view layout, the data displayed in a card's title is determined by a grid's main (primary) column. The content of the cell whose field name matches the field name of the main column will be displayed in the corresponding card's title. If left unmodified, the main column will be the first column that is added to a grid's Columns collection; however, the main column can be changed by setting a column's IsMainColumn property to true.

The CellContentTemplate of the main column is also used to display the default content of the scrolltip.

When a grid uses a TreeGridflowView, the column identified as being the "main" column (by setting this property to true) will display its data using a tree structure. In other words, in details the data of the cells associated with this column will be slightly indented.
