範例

下列程式碼範例示範如何使用 方法來初始化 ListView 詳細檢視，並自動調整資料行 AutoResizeColumns 的大小。 若要執行此範例，請將此程式碼貼到 Windows Form 中，並從表單的建構函式或 Load 事件處理常式呼叫 InitializeResizingListView2 方法。

private ListView resizingListView2 = new ListView();
private Button resizeButton = new Button();

private void InitializeResizingListView2()
{
    // Set location and text for button.
    resizeButton.Location = new Point(100, 15);
    button1.Text = "Resize";
    button1.Click += new EventHandler(button1_Click);

    // Set the ListView to details view.
    resizingListView2.View = View.Details;

    //Set size, location and populate the ListView.
    resizingListView2.Size = new Size(200, 100);
    resizingListView2.Location = new Point(40, 40);
    resizingListView2.Columns.Add("HeaderSize");
    resizingListView2.Columns.Add("ColumnContent");
    ListViewItem listItem1 = new ListViewItem("Short");
    ListViewItem listItem2 = new ListViewItem("Tiny");
    listItem1.SubItems.Add(new ListViewItem.ListViewSubItem(
            listItem1, "Something longer"));
    listItem2.SubItems.Add(new ListViewItem.ListViewSubItem(
        listItem2, "Something even longer"));
    resizingListView2.Items.Add(listItem1);
    resizingListView2.Items.Add(listItem2);

    // Add the ListView and the Button to the form.
    this.Controls.Add(resizingListView2);
    this.Controls.Add(resizeButton);
}

private void resizeButton_Click(object sender, EventArgs e)
{
    resizingListView2.AutoResizeColumns(ColumnHeaderAutoResizeStyle.HeaderSize);
}

Private resizingListView2 As New ListView()
Private WithEvents resizeButton As New Button()


Private Sub InitializeResizingListView2() 

    ' Set location and text for button.
    resizeButton.Location = New Point(100, 15)
    resizeButton.Text = "Resize"

    ' Set the ListView to details view.
    resizingListView2.View = View.Details
    
    'Set size, location and populate the ListView.
    resizingListView2.Size = New Size(200, 100)
    resizingListView2.Location = New Point(40, 40)
    resizingListView2.Columns.Add("HeaderSize")
    resizingListView2.Columns.Add("ColumnContent")
    Dim listItem1 As New ListViewItem("Short")
    Dim listItem2 As New ListViewItem("Tiny")
    listItem1.SubItems.Add(New ListViewItem.ListViewSubItem(listItem1, _
        "Something longer"))
    listItem2.SubItems.Add(New ListViewItem.ListViewSubItem(listItem2, _
        "Something even longer"))
    resizingListView2.Items.Add(listItem1)
    resizingListView2.Items.Add(listItem2)
    
    ' Add the ListView and the Button to the form.
    Me.Controls.Add(resizingListView2)
    Me.Controls.Add(resizeButton)

End Sub

Private Sub resizeButton_Click(ByVal sender As Object, _
    ByVal e As EventArgs) Handles resizeButton.Click

    resizingListView2.AutoResizeColumns(ColumnHeaderAutoResizeStyle.HeaderSize)
End Sub

備註

只有在 建構 和 包含 Form 之後，呼叫這個方法才有效 ListView ，而且資料 ListView 行標頭和資料行會填入專案。 如果將新專案新增至 ListView ，除非再次呼叫 ，否則資料行將不會調整大小 AutoResizeColumns 。
