XAF: New Web UI Theme, Templates and Optimizations for Desktop and Tablet Browsers (Coming soon in v15.1)


The new XAF Web application style is now shiping in v15.2+! Refer to the official ASP.NET Web Application Appearance documentation article for more details. In addition, see the eXpressApp Framework > Getting Started > XAF Mobile (CTP) Tutorial article to learn more on the new Mobile UI, which is technically is a single-page HTML5/JavaScript application (SPA) based on DevExtreme components that is ready to be compiled by Apache Cordova (PhoneGap) into a native package that can then be submitted to app stores.


So what do we have planned for XAF in this release? It all starts with the web...

As you can tell from the images below, we decided to change direction from our previous Web UI prototypes based on the Moderno theme (check here) and instead we've started implementing a brand new concept created by our UI designers. The result is an overhauled ASP.NET WebForms theme for XAF Web apps (it’s not available for our ASP.NET controls at present time), new webpage templates and associated optimizations for touch screen devices.  All of this should make accessing XAF web sites from both desktop and tablet browsers more intuitive for your end-users (I hope to talk about smartphones separately later this year).

In the upcoming release we wanted to share a preview (CTP) of our work to date so you can understand where we are heading. We hope to finalize all that we have planned with regard to look & feel, general UX, application flow and behavior by 15.2. It is likely that there will be more updates on this new web theme in the coming months.

At this time, we want to get your feedback and hear your thoughts. We want to work with you to create the best possible solution so you can build apps that address the widest possible use-cases going forward.


Here is a short video that demonstrates our responsive layout in action...so you can get a better sense of how an XAF web application adapts itself as browser width or orientation changes.

Our XCRM demo will use the new style by default. To learn more on how to enable this theme in your existing apps and see how it works for yourself and provide feedback/report issues, refer to this knowledge base article.

Very nice. I can definitely roll this right away into two production projects i have going.


1. A lot of padding going on between groups.

2. Looks terrible in portrait. I assume the menu collapse when changing between portrait and landscape.  

I can't wait to test the optimizations for touch screen devices. This is a requirement for one of my app and i am having some issues with the current themes.

@Aleksey: Not yet, although it is possible to implement a custom solution for this. BTW, would you please elaborate a bit more on your use-case scenario and tell us how often this data representation mode is going to be used in your app?

@Erik: Thanks for your feedback. We usually ship the second major release around early December.

Long time awaited/demanded. Thanks for that. Eventually DevExpress is going in the right direction.

Warning: What now comes may sound rude, however, it isn't intended to be rude!!

However, I was wondering, if it wouldn't be even better to push it one step further and support e.g. Bootstrap. This would give us much more flexibility. I think it's time for a non-proprietary solution.

XAF is sooo flexibel on many areas, but not on the presentation layer and this means to consider much more than just e.g. ConditionalAppearance.  

For the time being, the real strength of XAF is not the GUI. We are in the year 2015 and there has been a lot of improvement in the web-frontend-arena during the recent years.

In my opinion it's time to liberate this area and to take a REAL step forward.

Hello Xaf Team,

I'm very exited with this new theme. In fact, i'm going to use it in production in my app. Oe question:

Why in a desktop screen is not full width? limited by the following class:

.sizeLimit {

max-width: 1200px;

To answer the question regarding use cases for the master-detail mode: there is NO application I maintain not using master detail. All kind of data browsing operations are expected to have an interface similar to Outlook: On the left (or top) some list or tree of [contacts/documents/articles/assets/messages/tasks/accounts/...] with summary information and on the right (or bottom) the detail information. For small screens this is not useful, of course, but tablet and desktop screens are big enough these days.

I miss the Cancel-Button in the Edit-Mode. Is this intentional?

Great! Very nice!

I've tested this new UI with my project and I've found two problems:

1) there is a lot of space between controls

2) the fonts are very big

I know this is "the beauty" of this theme but in real applications with a lot of information to display...it becomes a real problem.

This is great!

It´s not working with Xtradashboards. Is there any possibility in 15.2 ?

3 October, 2015
Dennis (DevExpress Support)

@stwart marques: This issue was already corrected in v15.1.7.

Hi Dennis, it is possible to customize the style of this theme? eg. the color of the menus? or the color of the page background?

7 December, 2015
Dennis (DevExpress Support)

@Daniel, Rubén: Yes, you can do this as per www.devexpress.com/.../T292465. This procedure can be simplified in the future.
