Passing application settings to Controls in class library

Hi All,
I have just started using the applications settings feature to save user and system data. The first time my application runs it finds a variety of paths and sets up some user data. User data is then saved at run time (last selected path etc).

I have added application settings to my main form and populate these on start up. But here is my problem. I can not figure out how to pass these settings on to sub-controls I have developed in a class library.

my project is structured thus

+ Solution 'codecontroller' (4 projects)
+ CodeControl (windows application
- Properties
-Settings.settings
- MainForm.cs
- app.config
+ DatabaseLib (class lib)
+ GuiClassLib (class lib)
+ GuiControlLib (class lib)
- properties
Setting.settings
- app.config
- ReleaseControlBrowser (User Control)
- BuildManager (user Control)

In this example ReleaseControlBrowser and BuildManager are included in the main form on separate tabs. What I need to happen is on start up I want to be able to pass settings from the main form to the sub controls (in the guicontrollib) and at run time for the sub-controls to update the settings when required (on close or triggered by an action such as build).

Can anyone give me advice on this? I have tried a number of solution including adding a link to the app.config in the GuiControlLib but this didn't seem to work.

thanks in advance,
G

Just for completeness. I have went for a singleton object to hold the global settings and combined this with settings.settings to allow these values to be stored between runs.

You can use class properties.

In your sub control main class have properties e.g.

C#

public class SubControl1
{
    public Int32 Id
    {
         get;
         set;
    }
    //set more properties here
   //you can access these properties using the this.Id within your class or SubControl1.Id outside your class
}

In from your main form you can set and get the properties for your sub-controls
There are many tutorials on google to help here e.g.

C#

SubControl1.Id = 1; //or get value from your application settings
