First of all I create one Product class to store Product related information. public class Product { public string ProductName { get; set; } public string ProductDescription { get; set; } } Next I create a custom HashTable class and re-define the indexer to return Product instance. public class ProductHashTable:Hashtable { public Product this[string key] { get { if (base.ContainsKey(key)) return base[key] as Product; else return null; } } } Next I load the hashtable and show it on the page. aspx.cs code ======== public partial class WebForm2 : System.Web.UI.Page { public ProductHashTable productCollection; protected void Page_Load(object sender EventArgs e) { LoadData(); } private void LoadData() { productCollection = new ProductHashTable(); productCollection.Add(1 new Product { ProductName = Monitor ProductDescription = This is Monitor }); productCollection.Add(2 new Product { ProductName = Keyboard ProductDescription = This is Keyboard }); productCollection.Add(3 new Product { ProductName = Mouse ProductDescription = This is Mouse }); productCollection.Add(4 new Product { ProductName = CPU ProductDescription = This is CPU }); productCollection.Add(5 new Product { ProductName = WebCam ProductDescription = This is WebCam }); } } aspx code ======= Here you can pass the hashtable key from querystring to get the specific Product instance.

Thanks mate for your reply... Actually i was calling Product Detail page through JavaScript and this is not good for SEO point of view. For SEO we should show url in the View Page Source.Now i passed the URL through anchor tag and it is working fine for me. Thanks for your code that you gave me.Because of that Code my functionality is working smoothly.Thanks a lot mate :)

This is simple class public class clsHash { public Hashtable HT{get;set;} public clsHash() { HT = new Hashtable(); int[] intArr = new int[2] { 10 11 }; HT.Add(1 intArr); } public int[] getArr { get { return (int[])HT[1]; } } } This is aspx.cs code or server side code public partial class WebForm2 : System.Web.UI.Page { public clsHash _obj = new clsHash(); protected void Page_Load(object sender EventArgs e) { } } This is scripting i.e aspx This is how you can do.... There are other methods tooo..... If this method doesn't work for you let me know with full requirement.

Thanks for ur reply mate. Can i use HashTable with Classes also... I want to put getArr value in to the Class Property and access this Class Property in Client side like Can i use Class property in Client side?Please help me out.

You cant access hashtable items like ht[1].intArr[1]ht[1].intArr[2] ... because hashtable reference each object value through keys. You must reference each value by key. But you can write custom class in order to fulfill your requirement Hashtable ht = new Hashtable(); int[] intArr = new int[2]{1011}; ht.Add(1 intArr); int[] getArr = (int[])ht[1]; foreach (int _val in getArr) { Console.WriteLine(_val); }
