Hi Bruno - it was previously discussed here:
My app consists of a main project HTML file with the main HTML/CSS already defined, and direct forms for everything else. I want to be able to associate HTML templates with direct forms that won't over-write my main project HTML. My forms have no code at all - apart from simple code to set up bindings. I'm currently implementing the forms by dropping a TWebHTMLDiv on each form and copying the HTML from separate external files, but you can see how messy that quickly becomes.
In fact, although quite cool, the ability to specify separate HTML snippets inside controls is a maintenance nightmare. If it were possible to specify a new HTMLFile property for all controls that currently have the HTML strings property this would be a big improvement. Obviously it would need some parsing, e.g. the default might be to extract HTML within the body of the linked file at build time.
Thanks, Bob
