Products Catalog using Aspose.Cells

Please follow the following steps to add Products Catalog report using Aspose.Cells

    1. Add sample "Northwind.xls" file in "Spring.Northwind.Web\App_Data\xls" folder. You can find this file in Download package/Source code of this project.
    2. Open "Web.xml" file on the root of "Spring.Northwind.Web" and add the following lines inside objects node
        <object type="Cells/Catalog.aspx">
          <property name="ProductDao" ref="ProductDao" />
          <property name="CategoryDao" ref="CategoryDao" />
    3. Add a new folder named "Cells" in Spring.Northwind.Web.2010
    4. Add a new ASP.NET page named "Catalog.aspx" in Spring.Northwind.Web.2010\Cells folder.
    5. Add a link to this "Catalog.aspx" on "Default.aspx" so that you can access it when run the project in browser.
    6. Replace the html with
      <%@ Page Title="" Language="C#" MasterPageFile="~/Shared/MasterPage.master" AutoEventWireup="true" CodeBehind="Catalog.aspx.cs" Inherits="Spring.Northwind.Web.Cells.Catalog" %>
      <asp:Content ID="Content1" ContentPlaceHolderID="content" runat="server">
          <h2>Create Product Catalog report using Aspose.Cells for .NET</h2>
          <div class="componentDescriptionTxt">
              This demo illustrates how to create a well formatted Catalog report by using <a href="">Aspose.Cells for .NET.</a>

                  <li>Aspose.Cells component gives you the agility to report your data in a variety of ways.</li>
                  <li>Aspose.Cells component is fully functional for creating all types of reports.</li>

                  <li>You can display the information the way you want to see it.</li>
              The demo generates a Catalog of products in Northwind database.
              <ul class="noPaddingUl">
                  <li>It has a two-page report header and uses photos for each category. </li>
                  <li>It starts each category on a new page and keeps all records for a category on same page. </li>
                  <li>Spring.NET NHibernate is used to retrieve the data from the Products table of Northwind database, to generate the report. </li>
                  <li>You can either open the resultant excel file into MS Excel or save directly to your disk to check the results.</li>
