Pass textbox value to query on new page

I am trying to creat a page where the user enters text in a textbox, clicks a button which goes to another page that displays a gridew based on the value entered in the textbox.  i know this has been done a million times but for whatever reason I can not figure it out.  I obviously do not have much ASP.net experience so if there is a better way to do this please let me know.
 
thanks
