The problem with anchors is that theyonly anchor to the parent control/form, and when the control/form shrinks the controls overlap.

The problem with docking is that the change in size is only shown in the fill'd control, and there is only one of these.

What you want is to have the control container resize the child controls, for that you need to create an "AutoSizePanel", have that dock'd fill and then set your controls on the panel.

Here is the code for the "AutoSizePanel":

using System;
using System.Collections;
using System.ComponentModel;
using System.Drawing;
using System.Data;
using System.Windows.Forms;

namespace Workbench
{
/// <summary>
/// A panel that resizes controls automatically.
/// </summary>
public class AutoSizePanel : Panel
{
/// <summary>
/// Holds the control info.
/// </summary>
private Hashtable htInfo = new Hashtable();
/// <summary>
/// Flag to prevent recursive call.
/// </summary>
private bool bAllowResize = true;

/// <summary>
/// Required designer variable.
/// </summary>
private System.ComponentModel.Container components = null;

/// <summary>
/// Constructor.
/// </summary>
public AutoSizePanel()
{
InitializeComponent();
}

/// <summary>
/// Adds a control to the list of controls.
/// </summary>
/// <param name="e"></param>
protected override void OnControlAdded(ControlEventArgs e)
{
// Hold the resizing
bAllowResize = false;

// Create the original info
SizingInfo riData = new SizingInfo(e.Control);

// Add to table
htInfo.Add(e.Control, riData);

// BAck to normal
bAllowResize = true;

//
base.OnControlAdded (e);
}

/// <summary>
/// Removes a control from the list of controls.
/// </summary>
/// <param name="e"></param>
protected override void OnControlRemoved(ControlEventArgs e)
{
// Delete the info
htInfo.Remove(e.Control);

//
base.OnControlRemoved (e);
}

/// <summary>
/// Does the magic.
/// </summary>
/// <param name="e"></param>
protected override void OnResize(EventArgs e)
{
// Only once
if (bAllowResize)
{
// Set
bAllowResize = false;

// And apply to each control
foreach (Control ctl in this.Controls)
{
// Get the original info
SizingInfo riCtl = htInfo[ctl] as SizingInfo;

// Info available?
if (riCtl != null)
{
// Resize
riCtl.Resize(ctl);
}
}

// Reset
bAllowResize = true;
}

//
base.OnResize (e);
}

protected override void OnPaint(PaintEventArgs e)
{
// Hold the resizing
bAllowResize = false;

// Collect info
foreach (Control ctl in this.Controls)
{
// Get the original info
SizingInfo riCtl = htInfo[ctl] as SizingInfo;

// Info available?
if (riCtl != null)
{
// Update
riCtl.Update(ctl);
}
}

// Back to normal
bAllowResize = true;

//
base.OnPaint (e);
}


/// <summary>

/// </summary>
protected override void Dispose( bool disposing )
{
if( disposing )
{
if(components != null)
{
components.Dispose();
}
}
base.Dispose( disposing );
}

#region Component Designer generated code
