stored procedure

Question

Hi all
I am using stored procedure to search within crystal reports.I have used the code as follows.On search button click I have written:
//Search_button click//
SqlConnection con = new SqlConnection("Data Source=server;Initial Catalog=CR;User ID=uttam;Password=uttam");
SqlCommand cmd = new SqlCommand("spSearch",con);
cmd.Parameters.Add("@search1", SqlDbType.VarChar).Value = TextBox1 .Text;
cmd.Parameters.Add("@search2", SqlDbType.VarChar).Value = TextBox2 .Text;
cmd.CommandType = CommandType.StoredProcedure;
con.Open();
cmd.ExecuteNonQuery();
con.Close();
//stored procedure//
CREATE PROCEDURE spSearch
(
@Search1 varchar(50),
@Search2 varchar(50)
)
AS
BEGIN
SET NOCOUNT ON;
-- Insert statements for procedure here
SELECT *
FROM cr2 Where FirstName = @search1 and LastName= @search2
END
 
Now the issue is the changes are not been r eflected in the report viewer.is there anything that I am missing or I ahve to include in my code.
Its urgent Please reply
Thanks
