Event Data

The event handler receives an argument of type AfterSelectChangeEventArgs containing data related to this event. The following AfterSelectChangeEventArgs properties provide information specific to this event.

PropertyDescription
Type The select change (read-only). Indicates whether the change is selection of cells, rows, group-by rows or columns took place.
Remarks

The selectchange argument indicates what type of object or objects involved in the selection: rows, cells, or columns. When a row or column is selected, the cells contained in it are not considered selected.

This event is generated before one or more objects have been selected or deselected, either programmatically, or by user interaction.

The control's Selected property can be used to determine what object or objects are currently selected.

The BeforeSelectChange event, which occurs before one or more row, cell, or column objects have been selected or deselected, is generated before this event.

Example
Following code shows some of the information available in AfterSelectChange event. It writes out information on the new selection.
