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);

    // 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()

    resizingListView2.Columns.Add("ColumnContent")
    Dim listItem1 As New ListViewItem("Short")
    Dim listItem2 As New ListViewItem("Tiny")
