How to create an user control without graphic using c# -

how create user control without graphic?

when create user control using windows form control library, saw command line: public partial class usercontrol1: usercontrol. friend told me replace usercontrol1: usercontrol usercontrol1:component,idisposable. don't know component,idisposable is.

you can see friend talking if take @ 1 of other components can drop onto form don't have own interface:

public class backgroundworker : component  public class errorprovider : component, iextenderprovider, isupportinitialize  public class timer : component 

you can create own:

public class myveryowncomponent : component {     public string setting1 { get; set; }     public string setting2 { get; set; }      public void someimportantmethodyoucancall()     {        // ...     } } 

and drop on form: (you'll have rebuild first, show in toolbox)
