Several Questions (RTC-AddIns)

Hi together,

i have some questions to RTC AddIns:

1.) I want to integrate a whole form (not a Classic Form), which is created in C# into the RTC. It this possible? By open the Page in which the Form is integrated, following error occures:

Type: System.ArgumentException
Message: Das Steuerelement der obersten Ebene kann nicht zu einem Steuerelement hinzugefügt werden.

I don't know if it helps, but here is my code snippet:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Drawing;
using Microsoft.Dynamics.Framework.UI.Extensibility;
using Microsoft.Dynamics.Framework.UI.Extensibility.WinForms;

namespace my_Form
{
    [ControlAddInExport("FORM")]
    public class Class1 : WinFormsControlAddInBase
    {
        protected override Control CreateControl()
        {
             Form1 my_form = new Form1();
             my_form.Size = new Size(600, 400);
             return my_form;
        }
    }
}

2.) Is it possible to transfer Data from other parts of Page to the embedded form? If yes, how?

Thank you very much!!!
