Question

I have a AspxGriview on aspx page with id="grdManageFilterRoom". I am binding this grid by fetching some data from database. In case of any changes in Session["grdManageFilterRoom"] variable it is automatically reflected in Session["tmpGrdManageFilterRoom"] variable
I don’t know why it’s happening and I want to avoid this behavior. Any suggestion would be appreciated.

   Session["grdManageFilterRoom"] = NameIdPairs<Int32>.GetRooms(companyCode, companyPersonID);          
   grdManageFilterRoom.DataSource = Session["grdManageFilterRoom"];
   Session["tmpGrdManageFilterRoom"] = Session["grdManageFilterRoom"];

This:

Session["tmpGrdManageFilterRoom"] = Session["grdManageFilterRoom"];

makes both session variables point to same object (I’m guessing that GetRooms method returns reference type), basically it doesn’t matter if you are using Session["tmpGrdManageFilterRoom"] or Session["grdManageFilterRoom"] (because it is the same object).

If want to prevent this, then you need to clone those object(s).
