SUMMARY
The default behavior of the ListView control, when in Report View, is the ability to select only the item on the far left of the list. If you try to select any of the sub-items, nothing happens. Only the first item is available to be selected.

You can avoid this limitation by adding a ListView extended style, LVS_EX_FULLROWSELECT, to the current ListView style. With this extended style you can select any sub-item and the entire row will be selected.



Step-by-Step Example
 Start a new Standard EXE project. Form1 is created by default. Select Components on the Project menu. Click the check box next to "Microsoft Windows Common Controls 5.0," and then click OK. Add a ListView control (ListView1) to Form1. Add a CommandButton (Command1) to Form1.  Add the following code to the Form module:

Private Declare Function SendMessage Lib "user32" Alias _ "SendMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal _       wParam As Long, lParam As Any) As Long

Const LVS_EX_FULLROWSELECT = &H20 Const LVM_FIRST = &H1000 Const LVM_GETEXTENDEDLISTVIEWSTYLE = LVM_FIRST + &H37 Const LVM_SETEXTENDEDLISTVIEWSTYLE = LVM_FIRST + &H36

Private Sub Command1_Click Dim lStyle As Long lStyle = SendMessage(ListView1.hwnd, _          LVM_GETEXTENDEDLISTVIEWSTYLE, 0, 0) lStyle = lStyle Or LVS_EX_FULLROWSELECT Call SendMessage(ListView1.hwnd, LVM_SETEXTENDEDLISTVIEWSTYLE, _          0, ByVal lStyle) End Sub

Private Sub Form_Load 'Add two Column Headers to the ListView control Set clmAdd = ListView1.ColumnHeaders.Add(Text:="Name") Set clmAdd = ListView1.ColumnHeaders.Add(Text:="Date")

'Set the view property of the Listview control to Report view ListView1.View = lvwReport

'Add data to the ListView control Set itmAdd = ListView1.ListItems.Add(Text:="Joe") itmAdd.SubItems(1) = "05/07/97"

Set itmAdd = ListView1.ListItems.Add(Text:="Sally") itmAdd.SubItems(1) = "04/08/97"

Set itmAdd = ListView1.ListItems.Add(Text:="Bill") itmAdd.SubItems(1) = "05/29/97"

Set itmAdd = ListView1.ListItems.Add(Text:="Fred") itmAdd.SubItems(1) = "05/17/97"

Set itmAdd = ListView1.ListItems.Add(Text:="Anne") itmAdd.SubItems(1) = "04/01/97" End Sub

 Press the F5 key to start the program. Click one of the entries in the Date column and observe that nothing occurs. Click on an entry in the Name column and note that only the name is highlighted. Click the command button and then click on entries in each column. Note that an entire row can now be selected by clicking an item in either column.</li></ol>
