Hi,

i want to pass value from parent window to child window. the page which is in parent window is .asp page & the page page i want to open in child window is .aspx page. i want to post the values from parent to window to child window. the value which i will get into child window should be accessible into code behind as i want use that value for querying the database. i don't want to pass the value through query string as anyone can tamper the value, also i don't want to use session because user can open multiple windows so previous value may be overwrite.
please give me the solution for this
