Can checkboxes be removed from a .NET WinForms ListView at runtime?

Question

Is it possible to remove the checkboxes from a .NET WinForms ListView control at runtime?

The following code appears to have no effect when '.Checkboxes' has initially been set to 'true' and the control has rendered onto a form with checkboxes available for each list view item:

// C#:
testListView.BeginUpdate();  
testListView.Checkboxes = false;  
testListView.EndUpdate();

Is there a method that must be called to enact this change? What is the use of providing the .Checkboxes property when it defaults to 'false' and only has an effect if set to 'true'?

Hi,

I just created a sample project using VS 2008 with the following code and it seemed to have worked:

 private void Form1_Load(object sender, EventArgs e)
    {
        for (int i = 0; i < 10; i++)
        {
            ListViewItem lvi = new ListViewItem("Test");
            listView1.Items.Add(lvi);
        }
    }

    private void button1_Click(object sender, EventArgs e)
    {
        listView1.CheckBoxes = false;
    }

the properties for my listview are as follows:

        this.listView1.CheckBoxes = true;
        this.listView1.Columns.AddRange(new System.Windows.Forms.ColumnHeader[] {
        this.columnHeader1});
        this.listView1.GridLines = true;
        this.listView1.Location = new System.Drawing.Point(12, 12);
        this.listView1.Name = "listView1";
        this.listView1.Size = new System.Drawing.Size(224, 174);
        this.listView1.TabIndex = 0;
        this.listView1.UseCompatibleStateImageBehavior = false;
        this.listView1.View = System.Windows.Forms.View.Details;
