BUG: Changing ListItem.Selected Doesn't Change SelectedItem

• Standard, Professional, and Enterprise Editions of Microsoft Visual Basic, 32-bit only, for Windows, version 4.0

SUMMARY

Setting the Selected property of a ListItem object in a ListView control to True does not change the SelectedItem property of the ListView control to correspond to this ListItem.

WORKAROUND

To avoid this problem, use the SelectedItem property of the ListView control instead of the Selected property of an individual ListItem. Setting the SelectedItem property of a ListView control to a given ListItem will correctly modify the Selected property of that ListItem.

STATUS

Microsoft has confirmed this to be an issue in the Microsoft products listed at the beginning of this article. Microsoft is researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.

MORE INFORMATION

Steps to Reproduce

1. Start Visual Basic, or if it is already running, choose New Project from the File menu.

2. Add a single ListView control to Form1.

3. Add the following code to Form1:

   Option Explicit

      Private Sub Form_Load()
          Dim LI As ListItem
          Dim i As Integer
   
          For i = 1 To 3
              Set LI = listview1.ListItems.Add(, , "Test " & i)
              LI.Selected = True
          Next i
   
          Debug.Print "SelectedItem = " & listview1.SelectedItem.Text
   
          For i = 1 To 3
              Debug.Print listview1.ListItems(i).Text & ", Selected = " _
              & listview1.ListItems(i).Selected
          Next i
      End Sub
   
   

4. Press F5 to run the project. Notice the output in the debug window:

   SelectedItem = Test 1 Test 1, Selected = False Test 2, Selected = False Test 3, Selected = True

   Although the Selected property of each ListItem is correct, the SelectedItem property of the ListView control itself still refers to the first ListItem. Setting the Selected property of the ListItems did not modify the SelectedItem property of the ListView control. To work around the problem, set the SelectedItem property instead. For example, in this sample, change the Selected line inside the first For..Next loop from

         LI.Selected = True
   

   to:

         Set ListView1.SelectedItem = LI
   

   Running the project after this change has been made will cause the expected output (that is, the Text property of SelectedItem is now 'Test 3') to be displayed in the debug window.
