I am working through the Jump Start: Windows Forms Application - C# in VS 2003 and have a problem on Step 13 - Enhancing the DataGrids. The enhancement to the Orders DataGrid worked fine however the enhancement to the Order Detail DataGrid results in no change in appearance (headers, null display, size). I double checked the settings and can't find anything wrong. I'm certain I've missed something simple but as a newcommer to .NET I'm lost. Can someone give me a hint on to how to figure out why this isn't happening?

Here is the applicable Windows Form Designer generated code:

//
// grdOrderDetail
//
this.grdOrderDetail.AddRowsWithDownArrow = false;
this.grdOrderDetail.BindingSource = "OrderDetail";
this.grdOrderDetail.BindingSourceMember = null;
this.grdOrderDetail.ControlID = new System.Guid("00000000-0000-0000-0000-000000000000");
this.grdOrderDetail.DataMember = "";
this.grdOrderDetail.HeaderForeColor = System.Drawing.SystemColors.ControlText;
this.grdOrderDetail.Location = new System.Drawing.Point(24, 320);
this.grdOrderDetail.Name = "grdOrderDetail";
this.grdOrderDetail.Size = new System.Drawing.Size(432, 137);
this.grdOrderDetail.TabIndex = 28;
this.grdOrderDetail.TableStyles.AddRange(new System.Windows.Forms.DataGridTableStyle[] {
this.OrderDetailTableStyle});
//
// OrderDetailTableStyle
//
this.OrderDetailTableStyle.DataGrid = this.grdOrderDetail;
this.OrderDetailTableStyle.GridColumnStyles.AddRange(new System.Windows.Forms.DataGridColumnStyle[] {
this.DetailOrderID,
this.ProductID,
this.UnitPrice,
this.Quantity,
this.Discount});
this.OrderDetailTableStyle.HeaderForeColor = System.Drawing.SystemColors.ControlText;
this.OrderDetailTableStyle.MappingName = "OrderDetail";
//
// DetailOrderID
//
this.DetailOrderID.Format = "";
this.DetailOrderID.FormatInfo = null;
this.DetailOrderID.HeaderText = "Order ID";
this.DetailOrderID.MappingName = "OrderID";
this.DetailOrderID.NullText = "";
this.DetailOrderID.Width = 75;
//
// ProductID
//
this.ProductID.Format = "";
this.ProductID.FormatInfo = null;
this.ProductID.HeaderText = "Product";
this.ProductID.MappingName = "ProductID";
this.ProductID.NullText = "";
this.ProductID.Width = 75;
//
// UnitPrice
//
this.UnitPrice.Format = "";
this.UnitPrice.FormatInfo = null;
this.UnitPrice.HeaderText = "Price";
this.UnitPrice.MappingName = "UnitPrice";
this.UnitPrice.NullText = "";
this.UnitPrice.Width = 75;
//
// Quantity
//
this.Quantity.Format = "";
this.Quantity.FormatInfo = null;
this.Quantity.HeaderText = "Qty";
this.Quantity.MappingName = "Quantity";
this.Quantity.NullText = "";
this.Quantity.Width = 75;
//
// Discount
//
this.Discount.Format = "";
this.Discount.FormatInfo = null;
this.Discount.HeaderText = "Discount";
this.Discount.MappingName = "Discount";
this.Discount.NullText = "";
this.Discount.Width = 75;
