how to display everything using gridview table unless user selects dropdownlist
===

###Hi i have a stored procedure from where i am selecting columns for my table
@ID nvarchar(200)

AS

BEGIN

	SET NOCOUNT ON
	SELECT 
      [ID]
      ,[Subject]
      ,[From]
      ,[To]
      ,[Body]
      ,[Comment] From Status 
      where ID=@ID 
  
END

I have only one read only grid view table and a dropdown list with 2 options accepted,deny.I want page to load all the emails in the database first and then when user selects ID accepted or denied  to show that column emails.my problem is if all the emails are displayed in gridview when user selects options its not working or vice versa if options are working then all the emails are not diplayed when page loads.so i want everything to be displayed first unless user selects option
