HashTable getting null between requests

[C Sharp Mage]

Hello guys, here is what i am trying to do, i have a hashtable in a class that contains regular pairs(key,value) when i click an "Add" button i fill the hashtable, so life is good however when i try to search in the same hashtable after i fill it out , i click on a "Search" button this is where i loose the hashtable content. is there a way to keep the hashtable between page requests? i am using ASP.net 1.1 and IIS6.0 Thank you for the fast response in advance The Mage

Your class has no state between postbacks. You need to either stuff it into the session, or send it to the client in the viewstate. Someone told me yesterday that making it static would work, but I am dubious, LMK if you try it and it works.

well i did make its static and still not working i am still getting a null hash the viewstate is a good idea (performance wise) since it doesn't chew server resources but would you mind if you give me example? my example is public abstract class class1 { public Hashtable htable; public class1{ htable = new Hashtable(); } public virtual void theOperation(int operationType,ListBox theControl,string filterPair){} } public class class2 : class1 { public override void theOperation(int operationType,ListBox theControl,string textPair) { thePairList.Add(key,value); // where/how can i do the viewstate??? } Thank you The Mage

You would need to work out how to serialise a hash table and then override loadviewstate and saveviewstate. Personally, I think sending it to the client every time is the thng to avoid, but. Thanks for confirming my thoughts on the static thing.
