Hi, yesterday I was talking with a colleague about creating a complex html (no ajax) form using fcl-web.

I explained that I know two ways to do it, the first one is to create the html and return it in the Response.content property, the other is using templates. All CRUD operations must me handled by hand.

He told me that he is used to do it in the "ASP.Net way", that he can draw the form with the IDE and the CRUD operations are automatically handled.

Does anyone knows if there's a more simplier way to create HTML CRUD forms using lazarus and fcl-web?

I think it's just create your own framework. In Delphi I have a "mini-crud framework for creating CRUD quickly. DBware not use, only the standard widgets as TEdit, TMemo, etc.. Widget names correspond to the fields of the tables (using some prefixes like edtName where "name" is the field in the table). The Tag property is also used ... short, simple and fast. I think the same idea could be used to create a mini-framework for CRUD in HTML. That's what I want to do, so start using the fcl-web daily.

Offcourse there is, you can use the webdesign package for this. Only it uses some java for saving the data...

But it's not that difficult to create non-javascript components for this.

I know, but I understood the "(no ajax)" as : use only regular HTML.

There is a fpdatasetform.pp unit which does more or less what is asked, but it was never tested very well; So I hesitate to recommend it.

I used it in production. but because it was so difficult to design, I started the webdesign package.

But I still wouldn't recommend it. It's not that difficult to come up with a much better design. The basic building-blocks are available, now.

That's what I also thought.
