    Specifies the item from which to start the selection range.
    Syntax
    'Declaration
 

    Public Sub FromItem( _
   ByVal item As Object _
) 
    'Usage

   object item
)

    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
      
    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 );
