Step 5: Extending generated code

a. Change the alignment of the numeric DataGrid fields

• Open Editors/Products.aspx in the WebForm Designer
• Select the DataGrid control and open its Columns property editor
• Switch to the Format tab and select the Columns/ProductID/Items item in TreeView
• Choose the Right item in the Horizontal Alignment drop-down list
• Set the Right alignment for all other numeric fields
• Click OK

b. Change the alignment of the numeric text fields

• Switch from Design to HTML view
• Add style="text-align: right" to all the numeric asp:TextBox controls 

Figure 5.1

c. Display text values for foreign keys

• Modify the supplier column ItemTemplate by replacing 
  <asp:Label Text='<%# DataBinder.Eval(Container.DataItem, "SupplierID") %>' runat="server" />
  with
  <asp:Label Text="<%# GetSupplierName(Container.DataItem) %>" runat="server" />
• Open the code-behind class
• Add the GetSupplierName method as shown below

C#:
protected string GetSupplierName(object productsRow)
{
    using(RapTier.Tutorial.Db.Northwind db = new RapTier.Tutorial.Db.Northwind())
    {
        SuppliersRow supplier = db.SuppliersCollection.GetByPrimaryKey(
               Convert.ToInt32(DataBinder.Eval(productsRow, "SupplierID")));
        return supplier.CompanyName;
    }
}

VB.NET:
Protected Function GetSupplierName(productsRow As Object) As String
    Dim db As RapTier.Tutorial.Db.Northwind = _
                  New RapTier.Tutorial.Db.Northwind()
    Try
        Dim supplier As SuppliersRow = _
             db.SuppliersCollection.GetByPrimaryKey( _
             Convert.ToInt32(DataBinder.Eval(productsRow, "SupplierID")))
        Return supplier.CompanyName
    Finally
        db.Dispose()
    End Try
End Function


• Perform the same steps for the CategoryID column
