custom commands - 'RaiseCanExecuteChanged'

[jen]

I have a radDataform and I'm customizing the Commands using the DataFormCommandProvider.

In edit mode, when I change a property in my current item, I do some validation, and add or remove ValidationErrors manually.
At this point I need the Commit button to re-run its CanCommitEditExecute() logic, to realize it can't commit while there are validation errors.

How do i trigger the CanCommitEditExecute() logic to re-run?
if it were a DelegateCommand I would just call RaiseCanExecuteChanged() on it, but I can't find anything like that here.

thanks

Hi,

 We are using CommandManager, so that CommandManager.InvalidateRequerySuggested should do the trick. May, I ask you to try it on your side?

Thanks Ivan,
but DataFormCommandProvider doesn't have public access to anything called .InvalidateRequerySuggested()

I have found a way around needing this. Instead of updating the buttons, the user can click commit, it will go through validation, then stay in edit mode if the validation fails.
