hi i have a ribbon controls in my Xtraform that has some barButtonItem controls, i want to set my XtraForm.AcceptButton to one of these barButtonItem, but how to do ? i use this code in Form_Load event : this .AcceptButton = ( IButtonControl ) this .barBtn_Ok; but at runTime, the following error message...

Hi all, I have build some XtraUserControls that I put in a parent form along with some other TextEdits. This parent form has a typical "Ok" button, that has to be enabled only if the form has no errors (i.e: all controls are validated). I would like to integrate all of them into the DxValidationProvider...

Toc, toc... Any thoughts? I think this HAS to be an usual use case: "Disable OK button until form validates (including embedded xtraUserControls...)" Thanks for reading
