範例

下列程式碼範例示範如何使用 Position 的 ListViewItem 屬性。 若要執行此範例，請將下列程式碼貼到 Windows Form 中，然後從表單 Load 的事件處理方法呼叫 InitializePositionedListViewItems 。 按一下按鈕以查看專案重新置放。

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

備註

屬性 Position 應該在 建構 和 包含 ListView 之後 ListViewItem 設定。 Position當 包含 ListView 位於 或 List 檢視中 Details 時變更 屬性，不會影響專案的位置。 此外， Position 當 包含 ListView 的 屬性從 SmallIcon 、 LargeIcon 或 檢視變更為 List 或 TileDetails 時 View ，屬性會自動變更。 ListView當 位於 、 LargeIcon 或 Tile 檢視中 SmallIcon 時，設定 Position 專案的 屬性會導致 重新排列 中 ListView 所包含的其他專案。
