ListView.selection property

Gets an ISelection that contains the range of currently selected items.

Syntax

var selection = listView.selection;

Property value

Type: ISelection

An ISelection object containing the selected items.

Remarks

Determining the difference when the selection changes

The onselectionchanged event notifies you when the ListView control's selection changes, but it doesn't tell you how the selection changed.

To determine how the selection changed

1. Before the selection changes, cache the current selection by calling selection.getIndices and storing the result. selection.getIndices returns an Array that contains the indexes of the currently selected items.
   JavaScript

   Copy

   
   var prevSelection = lv.selection.getIndices(); 
   
   

   (Where lv is a ListView control.)

2. Register for the onselectionchanged event.
3. When the onselectionchanged event fires, call selection.getIndices again to get an Array of the currently selected item indexes.
   JavaScript

   Copy

   
   var currentSelection = lv.selection.getIndices();
   
   

4. Compare the two arrays. One way to calculate the difference is to use the Array.filter method.
