is there is any possible to achive this without store the current control set, and positions etc..

You need to look at something like

• Form and Control Position and Size Utility
• Save and restore Form position and layout with this component

Basically what it boils down to, is that you need a way to store the current control set, and positions (possibly values too) to some sort of storage (XML file, Registry, Database) when the user exits your form/application.

Then once they reopen the form/application, you need to retrieve these settings for the given user (if any is available) and restore the form/application to that state.

How about making extension methods to Control class? (Actually, appropriate .NET abstract base class, a sub-class of Control class, depending on UI. Do you use Windows Forms or XAML or ASP.NET?)

Something like:

public static class MyPositionExtensions{
    public static void SaveState(this Control c){ /* Save position to xml-file */ }
    public static void RestoreState(this Control c){ /* Load from xml-file */ }
}

Then in your closing just loop like

foreach(var c in MyControls)c.SaveState();

and opening like

foreach(var c in MyControls)c.RestoreState();
