Survey (~1min): Default location of the Reset View Settings Action - YOUR FEEDBACK IS NEEDED!!!

This command is provided by the standard ResetViewSettingsController and resets all the user customizations of the View's model. It may be helpful when your client customized a lot and was stuck getting things to normal. Due to this scenario the command is available in the main menu toolbar or ribbon by default (+additionally duplicated in context menu in WinForms).

However, we wanted to hear the XAF community thoughts on this default design after receiving several user requests in this regard (examples: one, two, three). As of now, we have no easy capability to know real usages and customizations of XAF Actions in end client apps, so we would greatly appreciate it if you participate in this and coming surveys. Thanks for your help in advance.

In fact, we already asked our user preferences when this feature was in development, but did not receive much feedback back then to hide this command from the main menu by default.

Tracing - How to exclude loaded assemblies from the eXpressAppFramework.log file

Just a small tip for XAF developers who have never needed or liked this large "Loaded assemblies" section written into the eXpressAppFramework.log file at startup or every time an exception is thrown:

Controller creation performance optimization v17.2 Preview - YOUR FEEDBACK IS NEEDED!

Starting with version 17.2, we've further optimized the process of creating Controllers that should positively affect forms loading performance and thus overall end user experience, especially in very complex detail forms.  In addition to List Property Editors (learn more about v17.1 improvements in this regard), Detail, Object and Lookup Property Editors, DashboardViewItem and popup windows created in a special way were supported. We are publishing this KB article prior to the 17.2 release to collect early user feedback and improve the overall stability:

If you are an active v17.1 subscriber and want to test this feature with your real world applications on a virtual machine (or another suitable test environment) prior to the official release, please leave a comment to this KB article or rather create a separate private ticket, so that we can verify your account and provide you with a v17.2 preview installation privately.

We would appreciate your thoughts and feedback once you've had the opportunity to try this new feature in your upgraded v17.2 project. Please report any issues and suggestions in our Support Center. Thanks for your help in advance!

How To: Use Google, Facebook and Microsoft accounts in ASP.NET XAF applications (OAuth2 authentication)

XAF security team has prepared a small demo illustrating the use of  OWIN OAuth 2.0 Authorization Server. Users can log in with their Google, Facebook or Microsoft accounts.

You can download the demo source code from DevExpress Support Center:
https://www.devexpress.com/Support/Center/Example/Details/T535280/

Technical details and instructions on how to use this approach in your existing applications are available in the example description in Support Center.


Your feedback is welcome!
We would greatly appreciate it if you try this example and share your feedback here in comments.

What happens when the current user is deleted (by himself/herself or another user) while still using the application?

Deletion of the user who is actively using the app is NOT handled by our security module at the moment (e.g., NullReferenceException and other errors may occur). That is mainly because this operation is very rare, and so far we have not received real-life scenarios from our users where this could be useful. Moreover, deleting by accident is already prevented by showing a confirmation message by the standard DeleteObjectsViewController > DeleteAction.

Refer to this Support Center ticket for more considerations and possible custom solutions.

Your feedback is needed!

Even though we do not provide ready solutions for this specific scenario, we will be more than happy to learn more about your experience in this regard to consider improvements to our product for the future. If you needed to handle such scenarios on your own, please elaborate more on your real-life requirements and implemented solutions. Thanks in advance.
