ListView Final Column Autosize creates scrollbar

Question

I am implementing a custom control which derives from ListView.

I would like for the final column to fill the remaining space (Quite a common task), I have gone abou

Answer 1

Try using the ClientSize property. As MSDN puts it:

The client area of a control is the bounds of the control, minus the nonclient elements such as scroll bars, borders, title bars, and menus.

Edit: I've added a code sample demonstrating how achieve different fill behaviors.

public class MyListView : ListView
{
    public MyListView()
    {
        View = View.Details;
        Columns.Add(Column1);
        Columns.Add(Column2);
        Columns.Add(Column3);
    }

    private readonly ColumnHeader Column1 = new ColumnHeader();
    private readonly ColumnHeader Column2 = new ColumnHeader();
    private readonly ColumnHeader Column3 = new ColumnHeader();

    protected override void OnResize(EventArgs e)
    {
        base.OnResize(e);

        // Constant width
        Column1.Width = 200;
        // 50% of the ListView's width
        Column2.Width = (ClientSize.Width/2);
        // Fill the remaining width, but no less than 100 px
        Column3.Width = Math.Max(100, ClientSize.Width - (Column1.Width + Column2.Width));
    }
}
