Funny comment. :doh: It's not like as if you can't use it with a model instead of a database.

Could be - in our project they "saved time" by using the same model across all tiers - so model and database is pretty much the same crap. There probably is a better way to build it with DevExpress reporting, I am not going to look for it though - it will be booted out instead of being corrected.

Seems to me that your problem isn't Devexpress, but the implementation of it. Anyway... Sometimes the best solution is to start over, and when you do, use the tools you know best.

So I'm editing some Crystal Reports again (excuse my inappropriate language). I have this one project that still uses them. I've searched for alternatives plenty of times, found stuff like DevExpress reporting, and heard good stuff about that one too. Not that I'm going to rewrite all reports for this particular project, but maybe for a future project. However, for other projects I don't even bother anymore and simply use MigraDoc and create PDF files in code manually. Writing stuff like:
frame = section.AddTextFrame();
frame.Width = "12cm";
frame.Left = "10cm";
frame.RelativeHorizontal = RelativeHorizontal.Margin;
frame.Top = "6cm";
frame.RelativeVertical = RelativeVertical.Page;It's not ideal, but it still beats CR (but pretty much anything would). To me, the whole reason to use a report generator like CR is that your clients can create their own reports. Kind of like a no-code solution for your reports. In practice, however, clients don't understand these tools anyway and still ask me to change reports for them. Meanwhile, a bit of code reuse ensures your reports have the exact same headers, footers, etc. while not being all that much harder for me (or even lots easier in case of CR). Thoughts? Generator vs. in-code? Your generator of choice?

We use SSRS still for a lot of our reports, but that is because we are cheap bastards with the reporting. We do have plans to stop using SSRS in place of another product at some time. SSRS is ugly but it works and it is fully compatible with VS and Sql Server, etc.

Planned to start later this year. Yes, implementation is a bigger problem than DevExpress. But let's just say I am not impressed with libraries that use catch {} (hours of my life I will not get back), nor am I impressed with ORMs that defaults to deferred deletion so in-experienced developers start using it without understanding how it is implemented (that was fun getting a large in-production database cleaned up). It does of course help the people writing the ORM at least knows how a guid is sorted by various databases... oh wait... they don't (or at least didn't on the version I looked at it).

Wow! I had the same revelation. Actually it never occurred to me to sort GUIDs. In my mind they were the epitome of randomly assigned, meaningless numbers. Why sort them? :confused:

They are generated sequential because random data is horrible for efficient indexes in large databases. Earlier versions of guids where constructed with the mac address + timestamp + a random component. Due to security concerns of leaking mac addresses (real or not) and the increase of software generated mac addresses this was changed. But some databases do - for compatibility reasons - keep the ordering based on the bytes that used to contain the timestamp.

Hand-coding PDF margins etc?? :omg: For most reporting, I tend to use HTML. If it's simple enough to use data-bound repeaters / grids, embed them in the page then render them on the server into an HTML string. For more complex reports combine that with external templates. Then shoot the resulting HTML into an HTML -> PDF converter (I use Pechkin, even though it has a bunch of dependencies and is 32-bit; but it generates a good result). That way all I need to do is adjust the HTML template or on-page data controls. Once the PDF is done, hide the data controls and show the page with a link to the PDF, or just redirect to the PDF - depending on requirements.

I haven't had any reporting needs for years now, but back when, I grew so tired of Crystal Reports that I converted everything I could and used this one instead: Perpetuum Soft Report Sharp-Shooter[^] As far as I recall, it was much easier to work with than Crystal...

For most of my 23 years programming, I've used Seagate/Crystal Reports/Crystal Decisions/Business Objects for reports in both desktop and web development. Lately, we have switched over to DevExpress which I really like. No ORMs for either one, just feed them a datatable, parameters, and formula fields. I'll also use straight up HTML for reports when the paging is somewhat predictable. :)

I think my logic and database logic are slightly different. Good thing we don't meet very often :D If you need "sequential GUIDs" why not just use a counter? Peano's Axioms basically say: if you've got enough bits, I've got enough numbers. If you want to make them unique over a number of different computers just add a computer GUID. In essence that's what version 1 and version 2 GUIDs do, except that they use a supposedly unique MAC address. Now I'll go my merry way trying to keep away from databases as much as I can :)

I inherited the project designed this way. One of the reasons given was a request to be able to clone the database and update it in different locations (no, the whole world does not yet have internet), but obviously that was never realized - and the problems that would need to be solved to support data merge are so huge that dealing with integer ids at the same time is not exactly making it a lot worse. X| The projects where I was responsible for the initial data design use integer ids - though if there is a specific use case that is served by using a guid as primary key in a low volume table I will of course do it. Typically anything above the data layer I simply lie and claim the ID is a string (or a struct of some kind) no matter what it is in the database. I do not want a UI to break because of something as trivial as changing primary key format in a table. Sure, gives a bit more conversion, but nothing that compares to the time spend waiting for data from the database.

:-) On the more serious side: RPG II became a standard report generator for more than one computer generation - more like a human generation :-) I saw RPG II in use in the 1980s, and according to Wikipedia, it is still in use, including for MS-Windows. We have the rule "If it works, don't fix it!" and apparently, RPG II still works (in some places).

Not necessarily so, it would depend on how the database is used. Random keys are good for writes. If you have a sequential key all inserts happens in the same leaf node at the end of the index which leads to waits because of pagelocks. Same goes for updates since most updates happens on fresh data. If you use a random key, all writes happen at random places which means pagelocks are more seldom a problem. Also, the index tend to stay balanced. The drawback with random keys is that they cause page splits. On a simple index this isn't a problem since it would happen every hundredth insert or so, but If the table is clustered the amount of page splits could probably cause serious performance issues. So, don't cluster a table on a random key since the drawbacks are serious and the advantage (index scan) is gone.

I roll my own. When I was first starting to learn C# (wow, was that really twenty years ago?) one project used ActiveReports and it was awful -- it may have improved since. A few years later I had to write a subsystem which could execute (previously defined) Crystal Reports (and provide values to any required parameters) -- which I hope I never have to do again. One of my main peeves with "reports" is that all too often someone walks into the office with a scruffy sheet of paper and says something like, "Joe used to run this report for me at the start of every month, but he's gone now, can you run it for me?" To which the only answer is "no". Even provided a soft-copy, no, I can't, I have no idea how it was generated. To wit -- the output does not contain the original input. So, what I chose to do for an employer about fifteen years ago was to define my own simple report engine. The report definition is in XML -- it basically only supports executing one SQL SELECT statement against a database, which was "good enough". The output is the same XML with the result data included (plus parameter values and such). So then, given a soft-copy of a report, I can feed it in as the input and re-run it -- providing new parameter values as required. The process then allows the recipient to view the report with either Excel or a Web Browser by using XSLT to transform the XML to either CSV or XHTML. Slick as snot. What's the next worst peeve about "reports" (in PDF or whatever)? Having a middle-manager bring one (a soft-copy I hope) to you and say, "we need you to load this data into our analysis database so we can analyze it". FFS! It came from a database; just get the raw data! Nope, they're not allowed access to the database. :sigh: Well, given one of my reports, they have the data in XML or CSV, so it's not that difficult to ETL into whatever analysis database they choose.
