If I set the Form to use Bootstrap CSS and drop a TWebPanel on it, the ElementClassName, ElementFont, etc. are set to suggested values. But if I drop a TWebStringGrid on the Form, all of those properties are blank, except ElementFont is set to efProperty.
What should be the suggested property values?
TWebStringGrid was not designed with having a bootstrap style in mind.
For a grid control with bootstrap style, we recommend TWebTableControl.
Thanks for the clarification, Bruno. I had thought that all of the TWeb* controls were designed to use bootstrap. I'm still crawling up the WEB Core learning curve with so much to learn yet. 
Is there a catalog of which controls are bootstrap ready?
