Examples

The following example initializes a ListView in detail view and automatically resizes the columns using the AutoResizeColumn method. To run this example, paste this code into a Windows Form and call the InitializeResizingListView method from the form's constructor or Load event handler.

private ListView resizingListView = new ListView();
private Button button1 = new Button();

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

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

    //Set size, location and populate the ListView.
    resizingListView.Size = new Size(200, 100);
    resizingListView.Location = new Point(40, 40);
    resizingListView.Columns.Add("HeaderSize");
    resizingListView.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"));
    resizingListView.Items.Add(listItem1);
    resizingListView.Items.Add(listItem2);

    // Add the ListView and the Button to the form.
    this.Controls.Add(resizingListView);
    this.Controls.Add(button1);
}

private void button1_Click(object sender, EventArgs e)
{
    resizingListView.AutoResizeColumn(0, 
        ColumnHeaderAutoResizeStyle.HeaderSize);
    resizingListView.AutoResizeColumn(1, 
        ColumnHeaderAutoResizeStyle.ColumnContent);
}

Remarks

Calling this method is only effective once the ListView and containing Form have been constructed, and the ListView column headers and columns are populated with items. If new items are added to the ListView, the columns will not resize unless AutoResizeColumn is called again.
