Parameters

item
An object representing the item from which to start the selection range.
Remarks
When specifying a start and end item as the selection range, the items will be selected according to their position in the data source and not how they are displayed on screen. This means that all items between the start and end items will be selected, regardless of where the start and end items are located visually.
Example
For more information and examples on selecting data, refer to the Selecting Data topic.
Dim range As New SelectionRange()

range.StartRangeInfos.FromItem( Me.People[ 5 ] )
range.EndRangeInfos.ToItem( Me.People[ 10 ] )

Me.sllbListBox.SelectedRanges.Add( range )
SelectionRange range = new SelectionRange();

range.StartRangeInfos.FromItem( this.People[ 5 ] );
range.EndRangeInfos.ToItem( this.People[ 10 ] ); 

this.sllbListBox.SelectedRanges.Add( range );
