In MdiParent toolstripmenuItem, I'm writing the code to show all the windows in cascade or Tile Horizontal style. My code is:

this.LayoutMdi(MdiLayout.Cascade);
this.LayoutMdi(MdiLayout.TileHorizontal);

This code will work in mdi parent only. But now I'm using a Split container in my Parent Form. In Panel1 I have buttons to Show the Form. In Panel2 My Forms will display, as:

        Forms.paymentPaid paidFm = new SalesandPurchases.Forms.paymentPaid();
        paidFm.MdiParent = this;
        paidFm.Left = (this.myPanel.Width - paidFm.Width) / 2;
        paidFm.Top = (this.myPanel.Height - paidFm.Height) / 2;
        myPanel.Controls.Add(paidFm);
        paidFm.Show();

Now Because of my Split Container my code( this.LayoutMdi(MdiLayout.Cascade)) is not working for cascade the windows in Panel2. Please tell me any other way.
