My UserControl is only displayed once.

Hi, I've got a simple UserControl:

	public class CtlStandardPlace : System.Windows.Forms.UserControl
	{
		private SimuObject m_place;
		public SimuObject Place
		{
			get
			{
				return m_place;				
			}
			set
			{
				m_place = value;	
			}
		}
		public CtlStandardPlace()
		{
			//
			// The InitializeComponent() call is required for Windows Forms designer support.
			//
			InitializeComponent();
			
/*			m_place = new SimuStandardPlace();
			m_place.X = 1;
			m_place.Y = 1;
			m_place.Dx = 10;
			m_place.Dy = 10;			
		*/
		}

		
		public CtlStandardPlace(SimuObject place)
		{
			m_place = (SimuStandardPlace)place;
		}
		
	
		#region Windows Forms Designer generated code
		/// <summary>
		/// This method is required for Windows Forms designer support.
		/// Do not change the method contents inside the source code editor. The Forms designer might
		/// not 
		/// 
		private void InitializeComponent() {
		
		this.Name = "CtlStandardPlace";
			this.Size = new System.Drawing.Size(10, 10);
		}
		#endregion
		
		protected override void OnPaintBackground(System.Windows.Forms.PaintEventArgs e)
		{
			base.OnPaintBackground(e);
			BrushFactory bf = new BrushFactory();
			SolidBrush brush;
			if(m_place != null)
			{				
				System.Drawing.Pen pen = new System.Drawing.Pen(System.Drawing.Color.Black);
				Rectangle rect = new Rectangle(m_place.X,m_place.Y,m_place.Dx,m_place.Dy);
				System.Diagnostics.Debug.WriteLine(rect.ToString());
				e.Graphics.DrawRectangle(pen, rect);				
				brush = bf.CreateBrush(m_place) as SolidBrush;
				System.Diagnostics.Debug.WriteLine(System.DateTime.Now.ToString() + brush.ToString() + brush.Color.ToString());
				if(brush == null)
					return;
				e.Graphics.FillRectangle(brush, rect.Left+1,rect.Top+1,rect.Right-1,rect.Bottom-1);
				e.Graphics.DrawString(this.ToString(), this.Font,
          brush, rect.Width + 3,
          (rect.Height - this.Font.Height) / 2);

			}		
		}
		
		protected override void OnPaint(System.Windows.Forms.PaintEventArgs e)
		{
			base.OnPaint(e);
			BrushFactory bf = new BrushFactory();
			SolidBrush brush;
			if(m_place != null)
			{				
				System.Drawing.Pen pen = new System.Drawing.Pen(System.Drawing.Color.Black);
				Rectangle rect = new Rectangle(m_place.X,m_place.Y,m_place.Dx,m_place.Dy);
				System.Diagnostics.Debug.WriteLine(rect.ToString());
				e.Graphics.DrawRectangle(pen, rect);				
				brush = bf.CreateBrush(m_place) as SolidBrush;
				System.Diagnostics.Debug.WriteLine(System.DateTime.Now.ToString() + brush.ToString() + brush.Color.ToString());
				if(brush == null)
					return;
				e.Graphics.FillRectangle(brush, rect.Left+1,rect.Top+1,rect.Right-1,rect.Bottom-1);
			}
		}
	}

and a simple testing programm:

		public MainForm()
		{
			//
			// The InitializeComponent() call is required for Windows Forms designer support.
			//
			InitializeComponent();
			
			//
			// TODO: Add constructor code after the InitializeComponent() call.
			//
			
			SimuEntryPlace dummy1 = new SimuEntryPlace();
			dummy1.X = 1;
			dummy1.Y = 1;
			dummy1.Dx = 10;
			dummy1.Dy = 10;		
			SimuBuilderControls.CtlStandardPlace place;			
			place = new SimuBuilderControls.CtlStandardPlace();		
			place.Place = dummy1;		  
		    this.Controls.Add(place);
		
			SimuStandardPlace dummy2 = new SimuStandardPlace();
			dummy2.X = 11;
			dummy2.Y = 1;
			dummy2.Dx = 10;
			dummy2.Dy = 10;
			place = new SimuBuilderControls.CtlStandardPlace();		
			place.Place = dummy2;		  
		    this.Controls.Add(place);
		    this.Invalidate();

		}

If i run that programm the first dummy-place is shown but the second is missing. It seems that I made something wrong, but I have no idea what it could be.

Anyone here got an idea?

Thanks

Would be easier if you'd put the code in a file that would compile.

Just looking at the code looks like the UserControl is 10x10 and dummy2.X = 11 ie. out of view.

I take it you are not using Visual Studio to create these examples?

Sorry for late reply, but I was on a buisness trip.
In the attachment there is my project. It is a #develop-project but it should also be easy to create a VS.NET-project from the files. Perhaps some sees what I was oversee.

Thanks in Advance
