Why not set the controls' values as dynamic properties and save the settings
to the app.config file ... for example:

/** ************************************** */
1. Create a static object for reading app.config file
/** ************************************** */

using System;
using System.Configuration;
using System.Xml;
using System.Windows.Forms;

sealed public class DynamicSettings
{
     private static AppSettingsReader m_SettingsReader = null;
     private static string m_ConfigFile = string.Empty;
     private static XmlDocument m_XmlConfigurationFile = null;

     static DynamicSettings()
     {
        m_SettingsReader = new AppSettingsReader();
        m_ConfigFile = Application.ExecutablePath + ".config";
        m_XmlConfigurationFile = new XmlDocument();
        m_XmlConfigurationFile.Load(m_ConfigFile);
     }
     
     public static string GetString(string name)
     {
        return(((string)(m_SettingsReader.GetValue(name, typeof(string)))));
     }
     public static int GetInt(string name)
     {
        try
        {
           return(((int)(m_SettingsReader.GetValue(name, typeof(int)))));
        }
        catch { return(0); }
     }
     public static double GetDouble(string name)
     {
        try
        {
        return(((double)(m_SettingsReader.GetValue(name, typeof(double)))));
        }
        catch { return(0.0d); }
     }
     public static float GetFloat(string name)
     {
        try
        {
           return(((float)(m_SettingsReader.GetValue(name, typeof(float)))));
        }
        catch { return(0.0f); }
     }
     public static bool GetBoolean(string name)
     {
        try
        {
        return(((bool)(m_SettingsReader.GetValue(name, typeof(bool)))));
        }
        catch { return(false); }
     }
     public static void Set(string name, object value)
     {
        try
        {
           XmlNode node =
m_XmlConfigurationFile.SelectSingleNode("//configuration/appSettings/add[@key='" + name + "']");
           node.Attributes["value"].Value = value.ToString();
           m_XmlConfigurationFile.Save(m_ConfigFile);
        }
        catch { }
     }
  }

/** ************************************** */
2. Make use of your dynamic settings : for example
   you might make an abstract Form for all of your
   applpication forms to sub-class
/** ************************************** */

public abstract class MyForm : System.Windows.Forms.Form
{
     public MyForm() : base() { _DynamicSettings(); }

     private void _DynamicSettings()
     {
        int val = 0;
        if((val = DynamicSettings.GetInt(Name.ToLower() + ".Top")) > 0)
           this.Top = val;
        if((val = DynamicSettings.GetInt(Name.ToLower() + ".Left")) > 0)
           this.Left = val;
        if((val = DynamicSettings.GetInt(Name.ToLower() + ".Width")) > 0)
           this.Width = val;
        if((val = DynamicSettings.GetInt(Name.ToLower() + ".Height")) > 0)
           this.Height = val;
     }

}

public class ApplicationForm1 : MyForm  { /* class definition  */ }
public class ApplicationForm2 : MyForm  { /* class definition  */ }

/** ************************************** */
3. Make entries in the .config file for your app
/** ************************************** */

<configuration>
 <appSettings>
   <!-- ApplicationForm1 -->
   <add key="applicationform1.Top" value="20" />
   <add key="applicationform1.Left" value="10" />
   <add key="applicationform1.Width" value="80" />
   <!-- ApplicationForm2 -->
   <add key="applicationform2.Top" value="20" />
   <add key="applicationform2.Left" value="100" />
 <appSettings>
<configuration>

/** ************************************** */
4. You will also most likely want to store any changes
    too, for example :
/** ************************************** */

public abstract class MyForm : System.Windows.Forms.Form
{
    // same implementation as above except for the following
     public MyForm() : base()
    {
         _DynamicSettings();
         this.Move += new EventHandler(this.Window_Moved);
    }
   
    protected void Window_Moved(object sender, EventArgs e)
    {
         string name = ((Form)sender).Name.ToLower();
         DynamicSettings.Set(name + ".Top", ((Form)sender).Top);      
         DynamicSettings.Set(name + ".Left", ((Form)sender).Left);      
    }
}

Hi,

If you are looking to store size, position changes in your form and also
want your form to reflect to screen resolution changes, take a look at Klik!
SizeLib.Net, it might help you :
