Windows Control Library Property Page problem

Fatih

Hi

I'm trying to do a control library. In my control library i have a class like that :

 public class Camera

    {
        private double Distance_;
        private double Far_;

        public double Distance
        {
            get
            {
                return Distance_;
            }

            set
            {
                Distance_ = value;
            }

        }

        public double Far
        {
            get
            {
                return Far_;
            }

            set
            {
                Far_ = value;
            }
        }

    }

In my class i have 2 pcs of double variable.

These codes show MyCamera in PropertyPage in C# (desing time)

 private Camera Camera_ = new Camera();
        public MyCamera Camera
        {
            get
            {
                Camera_ = new Camera();
                return Camera_;
            }
            set
            {
                Camera_ = value;
            }

        }

When i build solution i can see MyCamera in propery page but i can't see Distance and Far variables. I want to see as a treeview in property page. There should be + sign and when i press + sign , variables will shown.

How can i do this? Can someone help me.

Thanks in advance

I change Modifiers property from private to public. But there is no change. Still MyCamera property is look disable. Then i make different test. I used SizeF instead of Camera class just for testing. After this modifcation MyCamera showed Width and Heigth parameter in Propery Page. Then i switch Camera Class to Struct. But problem is still available. I think i have use some other defination or command in my camera class(or struct). But what is that i don't know??

Code is like that

    public class Camera
    {
        public double Distance_;
        public double Far_;

        public Camera(double distance, double far)
        {
            Distance_ = distance;
            Far_ = far;
        }

        public double Distance
        {
            get
            {
                return Distance_;
            }
            set
            {
                Distance_ = value;
            }
        }

        public double Far
        {
            get
            {
                return Far_;
            }
            set
            {
                Far_ = value;
            }
        }
    }

    public partial class TestControlLib : UserControl
    {
 
        private Camera Camera_;
        public Camera MyCamera_
        {
            get
            {
                if (Camera_ == null)
                {
                    Camera_ = new Camera(100, 100);
                }
                return Camera_;
            }
            set
            {
                Camera_ = value;
            }

        }


    }

Thanks for your reply.

I tested it but my problem is still available.

I put my Control Library on my Form. When i in "View Designer" mode, i can change some properties of my control in design time. But MyCamera properties look like a disabled and there is no my variables (Distance and Far). I can access by using code to MyCamera.

You can see in ss of my program.

Thanks in advance

ok a couple of things:

First the Code is Incurrect here is te fixed one:

 private Camera Camera_ ;
        public Camera MyCamera_         
        {
            get
            {
                if (Camera_ == null)
                      Camera_ = new Camera();             
                return Camera_;
            }
            set
            {
                Camera_ = value;
            }

        }

in order to access Camera properties just do the following :

MyCamera_.Distance;
MyCamera_.Far;

and so on
