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>");
     }
 }

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>
