示例

下面的代码示例演示如何使用 Position 的 ListViewItem属性。 若要运行此示例，请将以下代码粘贴到 Windows 窗体中，并从窗体Load的事件处理方法调用 InitializePositionedListViewItems 。 单击该按钮可查看重新定位的项目。

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

注解

应在Position构造 和 包含 ListView 之后ListViewItem设置 属性。 在包含 ListViewDetails 内容或List视图中时更改 Position 属性不会影响项的位置。 此外，Position当包含 ListView 的 属性从 SmallIcon、 或 视图List更改为 或 TileDetails时View，LargeIcon属性将自动更改。 ListView当 位于 SmallIcon、 LargeIcon或 Tile 视图中时，为项设置 Position 属性将导致重新排列 中包含的ListView其他项。
