示例

下面的代码示例演示如何初始化ListViewAutoResizeColumns详细信息视图并使用 方法自动调整列的大小。 若要运行此示例,请将此代码粘贴到 Windows 窗体中,并从窗体的构造函数或Load事件处理程序调用 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

注解

只有在构造 了 和 包含Form,并且ListView列标题和列填充了项后,调用此方法才有效ListView。 如果向 添加新项, ListView除非再次调用 ,否则 AutoResizeColumns 列将不会调整大小。
