ASP.NET how to premanently store variable in code behind (C#)

[amitb]

Hi, The problem is I am trying to declare "protected DataSet universeSet = new DataSet();" in my C# page behind the asp page. The variable is declared on the top of the page. I want the information to be stored inside the variable universeSet so I can retrieve it for later use.

Whenever I click a button on my webpage (asp:Button or asp:ImageButton), the information in universeSet seem to be erased, I think this is because it is reloading the C# page, which the line "protected DataSet universeSet = new DataSet();" declares a fresh DataSet with no information inside.

How can I avoid reloading the variable, I can't take out " = new DataSet();" or I will get NullPointerException.

Thank you.
