ItemSelectionChanged

This rule is triggered after the selection state of an item has successfully changed.
This happens when :

• the user clicks on the selection column of row in a data grid
• calling the SelectAllItemsAsync, SelectItemAsync, UnselectAllItemsAsync or UnselectItemAsync methods

When several items are selected at once, the rule is triggered once per selected item.

See this article for more information on event rules execution order.

Arguments

The Arguments property provides the following options.

Name	Type	Description
Item	The type of the UI view model	Instance of the item to whose selection changed.

Item versus DatasourceCurrent

Item refers to item that has been (un)selected. It is the same as using Arguments.Item.

Important

The current position can be completely different from the position of the item being selected, therefore, never assume that DatasourceCurrent refers to the item being selected.
