Simple method using Enum.Parse to change the dockstyle to control on form with combobox

ComboBox items do not have to be strings. The combobox calls ToString on each object in Items so simply add the enum values to the combobox.

using System;
using System.Drawing;
using System.Windows.Forms;


namespace Anchor_Form
{
    public class Form1 : Form
    {
		public Form1()
		{
			InitializeComponent();
		    
			foreach (DockStyle style in Enum.GetValues(typeof(DockStyle)))
				comboBox1.Items.Add(style);

			comboBox1.SelectedIndex = 0;
		}

		private void InitializeComponent()
		{
			panel1		= new Panel();
			comboBox1	= new ComboBox();
			SuspendLayout();
			// 
			// panel1
			// 
			panel1.BackColor = SystemColors.ControlDarkDark;
			panel1.Location = new Point(43, 60);
			panel1.Name = "panel1";
			panel1.Size = new Size(200, 100);
			panel1.TabIndex = 0;
			// 
			// comboBox1
			// 
			comboBox1.DropDownStyle = ComboBoxStyle.DropDownList;
			comboBox1.Location = new Point(61, 178);
			comboBox1.Name = "comboBox1";
			comboBox1.Size = new Size(121, 21);
			comboBox1.TabIndex = 1;
			comboBox1.SelectedIndexChanged += new EventHandler(comboBox1_SelectedIndexChanged);
			// 
			// Form1
			// 
			AutoScaleDimensions = new SizeF(6F, 13F);
			AutoScaleMode = AutoScaleMode.Font;
			ClientSize = new Size(284, 264);
			Controls.Add(comboBox1);
			Controls.Add(panel1);
			Name = "Form1";
			Text = "Form1";
			ResumeLayout(false);
		}

		private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
		{
			panel1.Dock = (DockStyle)comboBox1.SelectedItem;

			comboBox1.BringToFront();
		}

		Panel		panel1;
		ComboBox	comboBox1;
	}
}
