I have a DxErrorProvider on my form (layoutControl) and it is worrking correctly, I can set or unset the error. My problem is that there is no way that I can tell if there are any errors on my form.

I am trying to accomplish two things:

1) When an error state is changed (Set or unset, type changed, etc) (Basically any call to SetError) I would like to update my OK button in accordance if the form is valid or not (Enabled, Disabled)

2) Access the total number of error and/or get a list of controls that have some error condition or better yet by condition type (Critical, Warning, etc)

Am I missing something? Does anyone have any similar experiances? I am thinking about creating my own control based on the DxErrorProvider to expose the required features.

You have go through all controls and check their errors:

hier is an example

                foreach (Control control in gcCustomer.Controls)
                    if (dxErrorProviderCust.GetError(control) != string.Empty && dxErrorProviderCust.GetErrorType(control) == ErrorType.Critical)
                    {

                        //There is an error with type critical
                        return false;
                    }

                return editCustomer.IsDirty;

This is just some code which simply shows you how to get error and error type for a control.

I think this is what you meant, if not please explain.

That is insanely inefficient,e specially if you just want to get the number of each condition.

 What I ended up doing is creating a utility class that uses reflection top pull back the hashtable that the DxErrorProvider uses internally and return the information from there.

 
I know I could have built a new version of the control, but the way I see it the utility class will be easier to maintain with future DX updates.

 
Thank you for the response. I would recommend that in future releases they add methods to get counts and possibly the errorItems as this could would be relatively easy to write.
