Eval vs foreach? frontend

Sat, 06 Aug 2011 21:17:31 GMT

Hej,

jeg har arbejdet en del med C#, men ikke s� meget med asp delen.
Jeg har l�st og l�rt om Eval, og bruger det nu, men
hvordan kan jeg lave eval, s� det svarer til dette?

CSharp kode

 foreach(Category cat in this.CategoryList)
 {
     Respone.Write("<div>" + cat.Name + "</div>");
 
     foreach(SubCategory subCat in this.SubCategoryList.Where(o => o.PID == cat.ID))
     {
         Respone.Write("<div>" + subCat.Name + "</div>");
     }
 }

S� langt er jeg n�et:

CSharp kode

 <asp:DataList ID="DataList_CategoryList" runat="server">
     <HeaderTemplate>
     </HeaderTemplate>
     <ItemTemplate>
         <div class="productCategory" style="margin-left: 25px;" runat="server">
             <div class="productCategoryName">
                 <%# Databinder.Eval(Container.DataItem, "Name").ToString().Replace(Environment.NewLine, "<br />") %>
             </div>
             <div class="productSubCategory" style="margin-left: 25px;">
                 <div class="productSubCategoryName">
                      //************************************************//
                 </div>
             </div>
         </div>
     </ItemTemplate>
     <FooterTemplate>
     </FooterTemplate>
 </asp:DataList>

CSharp kode

 public partial class WebUserControl1 : System.Web.UI.UserControl
 {
     IList<Product> _productList;
     IList<Category> _categoryList;
     IList<SubCategory> _subCategoryList;
 
     public IList<Product> ProductList { get { return this._productList; } }
     public IList<Category> CategoryList { get { return this._categoryList; } }
     public IList<SubCategory> SubCategoryList { get { return this._subCategoryList; } }
 
     protected void Page_Load(object sender, EventArgs e)
     {
         this._categoryList = new List<Category>();
         this._subCategoryList = new List<SubCategory>();
         this._productList = new List<Product>();
 
         loadSubCategories();
         loadCategories();
         loadProducts();
 
         BindCategoryList();
     }
 
     private void BindCategoryList()
     {
         try
         {
             SqlConnection sqlConn = new SqlConnection(ConfigurationManager.ConnectionStrings["ConnectionString2"].ConnectionString);
             SqlCommand sqlCommand = new SqlCommand("select * from ProductCategories ", sqlConn);
 
             sqlCommand.Connection.Open();
 
             DataList_CategoryList.DataSource = sqlCommand.ExecuteReader();
             DataList_CategoryList.DataBind();
 
             sqlCommand.Connection.Close();
             sqlCommand.Connection.Dispose();
         }
         catch (Exception exc)
         {
             Console.WriteLine(exc.ToString());
         }
     }
 
     private void loadProducts()
     {
         this._productList = SqlClass.SelectProducts();
 
         this._productList.Add(new Product(0, "Shit", "This is a shitty product. 2kg.", 14.39, 7, 1, 0, false));
         this._productList.Add(new Product(1, "Crap", "This sure is crap! 2kg.", 299.95, 23, 1, 0, false));
     }
 
     private void loadSubCategories()
     {
         this._subCategoryList = SqlClass.SelectSubCategories();
     }
 
     private void loadCategories()
     {
         this._categoryList = SqlClass.SelectCategories();
     }
 }
