Reset all information on a page

I am a web page.  There are textboxes and dropdowns that user selects.  A search button that uses the user selects and return the results to a datagrid. 


I want  a clear button that will blank out the textboxes and resets the dropdowns.  I used OnClientClick="javascript:window.location.reload();" but that does work if the search button is used.  Please show me a way to code a button that clear all the textboxes and dropdowns.  Thanks.
