If you need hosting for your XAF application take a look to Contabo VPS. We have been using it for more than 10 years with great results.

Disclaimer: We are affiliate it to Contabo. Profits generated by this link will be used for covering cost of Meetup subscription, XAFers Weekly hosting and other community events.

Browsing the support center I found this nice trick to focus the accordion navigation control with a shortcut.

As always, I decided to (besides bookmark it 😎)  do a quick post to refer to it later on.

So, let’s see it in action:

Let’s do this together. Let’s review all XAF modules, one by one each week.

First, all official DevExpress modules, then all community modules,  LLamachant modules, Ultra modules, eXpand and more…

So when are we starting? We already did 😎

Audit Trail Module

See you next time. XAF out!

Have you had this request before? A Token PropertyEditor? One of our students had a client asking for this, so as always, we started by searching the support center and voila, we found an implementation that with minimal changes was up and running in no time.

Let’s take a look at the code:

Yes I did, inspired by my friend and DevExpress MVP Joche I decided to give it a try and start my own channel, also Javier Suarez in .Net Conf Xamarin sounds like me (a thick Spanish accent) so why not? If you are interested in XAF, XPO and Xamarin (and if you are here, you probably are) then subscribe and I will try to have new content every 15 days or at least monthly.

What would you guys think about a series of videos reviewing all XAF modules, the ones from DevExpress first and then all modules done by the community?

Here is the link for the channel:

Lastly, I am really excited to say that xafers.training is finally live. We plan to host sessions two Saturdays a month covering XAF, XPO, Xamarin and a lot more. We are starting with 5 courses:

• Getting Started with XAF
• Getting Started with XPO. One ORM to rule them All
• Getting Started with XPO and Xamarin
• Getting Started width OData (Server & Client)
• XAF Reusable Modulos

Well, that is it for today. See you next time. XAF out!

First, I have to admit CSS and Javascript are not my stronger points. With that out of the way, some times a simple change makes a big difference in the appearance of your app.

Well, let’s change the color of the header bar in our XAF Web application.

public class AddStyleController : ViewController
    {

        protected override void OnViewControlsCreated()
        {
            base.OnViewControlsCreated();

            LiteralControl style = new LiteralControl();
            style.Text = "<style type='text/css' scoped>.white { background-color: palegreen; }</style>";
            ((Control)View.Control).Controls.Add(style);


        }
    }

And good to go:

Until next time, XAF out!
