Create tabke like

id	int	
likedis	bit	
productid	int	
userid	varchar(150)

make unique constraints on (productid,userid)

Create stored procedure like

SQL

ALTER PROCEDURE [dbo].[inslike]
	
	
	
	@aid int,
	@userid varchar(150)
	
	as
BEGIN
begin try
	 BEGIN TRANSACTION 
	insert into tbllike (likedis,productid,userid) values(1,@aid,@userid);
	update tblProduct set like1=like1+1 where ID=@aid;
	Commit
	end try
	begin catch
	ROLLBACK
	end catch
	
END

on like buttonclick

C#

SqlCommand cmd = new SqlCommand();
                cmd.Connection = GetConnection();
                cmd.CommandText = "inslike";
                cmd.CommandType = CommandType.StoredProcedure;
                cmd.Parameters.AddWithValue("@aid", int.Parse(e.CommandArgument.ToString()));
                cmd.Parameters.AddWithValue("@userid", Session["userid"].ToString());
                cmd.ExecuteNonQuery();
                cmd.Connection.Close();
                getData();
