Adjust ListView columns to fit with WinForms

Question

I have face resize problem of listview columns. If you anchor/docking the listview to normal winform than the listview anchor or docking works well. I mean lis

Here's my solution;

Instead of resize event I prefer resizeEnd of form, so that the code will run only once when the resize is complete.

private void Form1_ResizeEnd(object sender, EventArgs e)
{
    this.ResizeColumnHeaders();
}

The ResizeColumnHeaders function sets all columns except the last one to fit against column-content. The last column will be using the magic-value hinted by LexRema.

private void ResizeColumnHeaders()
{
    for (int i = 0; i < this.listView.Columns.Count - 1;i++ ) this.listView.AutoResizeColumn(i, ColumnHeaderAutoResizeStyle.ColumnContent);           
    this.listView.Columns[this.listView.Columns.Count - 1].Width = -2;
}

Also don't forget to call ResizeColumnHeaders() after you load your initial data;

private void Form1_Load(object sender, EventArgs e)
{            
    this.LoadEntries();
    this.ResizeColumnHeaders();
}

One more thing is to prevent flickering while columns-resizes, you need to double-buffer the listview.

public Form1()
{
    InitializeComponent();            
    this.listView.DoubleBuffer();            
}

DoubleBuffer() is actually an extension for easy use.

public static class ControlExtensions
{
    public static void DoubleBuffer(this Control control) 
    {

        if (System.Windows.Forms.SystemInformation.TerminalServerSession) return;
        System.Reflection.PropertyInfo dbProp = typeof(System.Windows.Forms.Control).GetProperty("DoubleBuffered", System.Reflection.BindingFlags.NonPublic | System.Reflection.BindingFlags.Instance);
        dbProp.SetValue(control, true, null);
    }
}
