This is what I want to do and I am struggling with it:
I have a property which gets displayed in the property grid and when
the user clicks on it, a form shows up which allows the user to select
multiple email id's and when he clicks OK, the list should be displayed
for the property as a comma seperated string.
I am not able to even show the form currently. This is what I have:
property displayed in grid:
private EMailUserList to;
       public EMailUserList To
       {
           get
           {
               return to;
           }
           set
           {
               to = value;
           }
       }

EMailUserList consist of:
public class EMailUsers
   {
       private string emailList = default(string);
       public string EMails
       {
           get
           {
               SelectUsers users = new SelectUsers();
               if (users.ShowDialog() == DialogResult.OK)
               {
                   emailList = users.EMailList;
               }
               else
                   emailList = String.Empty;
               return emailList;
           }
           set
           {
               emailList = value;
           }
       }

       public override string ToString()
       {
           return emailList;
       }
   }

and SelectUsers is the form.

Also if I have a property which returns an Array/ArrayList i can see
the button with 3 dots coming up in property grid, which I don't get,
how do I achive this.

I know I am doing something very wrong and might have to write a type
converter but I am not able to even figure out what type converter to
write and where?
Thanks a bunch,
Mav.
