DisplayedItem (Property)

In french: RubriqueAffichée

The DisplayedItem property is used to:

Find out the item or the variable displayed by the control.
Modify the item or the variable displayed by the control.

Remarks:

In the report "Opening" event, this property is used to modify the item displayed in a control when the data source of the report is modified through programming (by SourceName for example).
If this property is used in the control "Before printing" event, the change will be performed the next time the control is printed (indeed, the item value is already read when running the control "Before printing" event).
The displayed item can come from a data file, a view or a query.
The stored item or variable is defined in the window or page editor, in the "Content" tab of the control description.

For a ListView control, this item corresponds to the caption displayed in the ListView control.

A number of items lower than the number of columns in the Table control, the "additional" columns will not be associated with any item (or variable).

Remark: To associate a column with an item or with a variable, use DataBinding.
