Is it possible to return an Array of Controls that have defined events from a webservice to a consumer?

----------------------------------------
consumer:
----------------------------------------
controls = Webservice.CreateGUI()

----------------------------------------
webservice:
----------------------------------------
using System;
using System.Collections;
using System.ComponentModel;
using System.Data;
using System.Diagnostics;
using System.Web;
using System.Web.Services;
using System.Windows.Forms;
namespace GUIService{
    public class GUIService1 : System.Web.Services.WebService{
        [WebMethod]
        public Control[] InitializeInterface(){
            Control[] cc = new Control[1];
            Button but = new Button();
            but.Location = new System.Drawing.Point(100, 100);
            but.Name = "button2";
            but.Size = new System.Drawing.Size(128, 32);
            but.TabIndex = 0;
            but.Text = "button2";
            but.Show();
            but.Click += new System.EventHandler(this.button2_Click);

            cc[0] = but;

            return cc;
        }

        private void button2_Click(object sender, System.EventArgs e){
            MessageBox.Show("test");
        }
    }
}

I'd tried but I get a serialization error and cannot figure out the problem.

"Cannot serialize member System.ComponentModel.Component.Site of type System.ComponentModel.ISite because it is an interface."

Any help would be great. Thanks

Whatever you are returning from WebMethod shd be serializable. For that what
you can do is store cotrol name & properties as XML DataSet and sendback to
client. There can access the DataSet the can create the UI controls.
