Selected Property

Microsoft Access Visual Basic

Selected Property

       

You can use the Selected property in Visual Basic to determine if an item in a list box is selected. Read/write Long.

expression.Selected(lRow)

expression   Required. An expression that returns one of the objects in the Applies To list.

lRow  Required Long. The item in the list box. The first item is represented by a zero (0), the second by a one (1), and so on.

Remarks

The Selected property is a zero-based array that contains the selected state of each item in a list box.

Setting Description
True The list box item is selected.
False   The list box item isn't selected.
You can get or set the Selected property by using Visual Basic.

This property is available only at run time.

When a list box control's MultiSelect property is set to None, only one item can have its Selected property set to True. When a list box control's MultiSelect property is set to Simple or Extended, any or all of the items can have their Selected property set to True. A multiple-selection list box bound to a field will always have a Value property equal to Null. You use the Selected property or the ItemsSelected collection to retrieve information about which items are selected.

You can use the Selected property to select items in a list box by using Visual Basic. For example, the following expression selects the fifth item in the list:

Me!Listbox.Selected(4) = True

Example

The following example uses the Selected property to move selected items in the lstSource list box to the lstDestination list box. The lstDestination list box's RowSourceType property is set to Value List and the control's RowSource property is constructed from all the selected items in the lstSource control. The lstSource list box's MultiSelect property is set to Extended. The CopySelected( ) procedure is called from the cmdCopyItem command button.

Private Sub cmdCopyItem_Click()
    CopySelected Me
End Sub

Public Sub CopySelected(ByRef frm As Form)

    Dim ctlSource As Control
    Dim ctlDest As Control
    Dim strItems As String
    Dim intCurrentRow As Integer
    
    Set ctlSource = frm!lstSource
    Set ctlDest = frm!lstDestination
    
    For intCurrentRow = 0 To ctlSource.ListCount - 1
        If ctlSource.Selected(intCurrentRow) Then
            strItems = strItems & ctlSource.Column(0, _
                 intCurrentRow) & ";"
        End If
    Next intCurrentRow
    
    ' Reset destination control's RowSource property.
    ctlDest.RowSource = ""
    ctlDest.RowSource = strItems
    
    Set ctlSource = Nothing
    Set ctlDest = Nothing

End Sub
