Hello Ludovic,
Thank you for writing.
If you are talking only about converting
Forms to
RadForms, this will be as easy as changing the name your form descends from i.e
Form is replaced by
RadForm. However, if you are talking about changing all your application controls from the standard Microsoft controls to RadControls for WinForms, such a conversion should be done manually for each control. We are trying to keep our API as close as possible to Microsoft's API in order to make such a transition easier.
In regards to the second question, I am not quite sure that I can fully understand your current approach, however, I will suggest to use for a main form
RadRibbonForm (since you want a ribbon on the main form) and then, add your child forms as MDI children. Attached to this post you can find a demo of this approach.
I hope that you find this information helpful. Should you have any other questions, do not hesitate to contact us.
Regards,
Stefan
