Examples

The following code example demonstrates how to use the Position property of a ListViewItem. To run this example, paste the following code into a Windows Form and call the InitializePositionedListViewItems from the form's Load event-handling method. Click the button to see the items repositioned.

private ListView positionListView;
private ListViewItem moveItem;
private Button button1;

private void InitializePositionedListViewItems()
{
    // Set some basic properties on the ListView and button.
    positionListView = new ListView();
    positionListView.Height = 200;
    button1 = new Button();
    button1.Location = new Point(160, 30);
    button1.AutoSize = true;
    button1.Text = "Click to reposition";
    button1.Click += new System.EventHandler(button1_Click);

    // View must be set to icon view to use the Position property.
    positionListView.View = View.LargeIcon;
  
    // Create the items and add them to the ListView.
    ListViewItem item1 = new ListViewItem("Click");
    ListViewItem item2 = new ListViewItem("OK");
    moveItem = new ListViewItem("Move");
    positionListView.Items.AddRange(new ListViewItem[] 
        { item1, item2, moveItem });

    // Add the controls to the form.
    this.Controls.Add(positionListView);
    this.Controls.Add(button1);
}

private void button1_Click(object sender, EventArgs e)
{
    moveItem.Position = new Point(30, 30);
}

Private positionListView As ListView
Private moveItem As ListViewItem
Private WithEvents button1 As Button


Private Sub InitializePositionedListViewItems() 
    ' Set some basic properties on the ListView and button.
    positionListView = New ListView()
    positionListView.Height = 200
    button1 = New Button()
    button1.Location = New Point(160, 30)
    button1.AutoSize = True
    button1.Text = "Click to reposition"

    ' View must be set to icon view to use the Position property.
    positionListView.View = View.LargeIcon
    
    ' Create the items and add them to the ListView.
    Dim item1 As New ListViewItem("Click")
    Dim item2 As New ListViewItem("OK")
    moveItem = New ListViewItem("Move")
    positionListView.Items.AddRange(New ListViewItem() _
        {item1, item2, moveItem})
    
    ' Add the controls to the form.
    Me.Controls.Add(positionListView)
    Me.Controls.Add(button1)

End Sub

Private Sub button1_Click(ByVal sender As Object, ByVal e As EventArgs)
    moveItem.Position = New Point(30, 30)
End Sub

Remarks

The Position property should be set after the ListViewItem and containing ListView are constructed. Changing the Position property when the containing ListView is in Details or List view will have no effect on the position of the items. Also, the Position property will automatically change when the View property of the containing ListView is changed from SmallIcon, LargeIcon, or Tile view to List or Details. When the ListView is in SmallIcon, LargeIcon, or Tile view, setting the Position property for an item will cause the other items contained in the ListView to be rearranged.
