Issue 22

JOSE JAVIER COLUMBIE

Hello XAFers,

We are back. This issue is completely focused in what is coming for v20.1 (still in Beta) but expected to ship in May 2020 (just a few days away).

A lot of great links/documentation. Really cool enhancements for the WinForms Data Grid, Security Permissions for UI Actions and more Blazor and .Net Core.

We wanted to apologize to the students that registered for the XPO and Xamarin training and did not receive the zoom link. We had some issues on the site and not all invitations email were sent correctly. If you were one of them, don't worry, we will be sending you the video of the class in the next few days.

That is all for now, everyone have a great week. XAF out!

Getting Started

Spreadsheet Document API - An Old Excel Format and the Covid-19 Pandemic

This is not directly related to XAF but wanted to give a shout out to the DevExpress Team who added support for Excel 2 in their Spreadsheet Document API to help a medical device manufacturer company in these uncertain times of the Covid-19 Pandemic. This is how a company gain customers for life. Well done!

XAF

Default XAF configuration options and feature toggles | DevExpress Support

This is an old article but I always comeback to it, and they are always adding new feature toggles. This time is the DevExpress.ExpressApp.SecurityStrategy.EnableSecurityForActions that enables the security actions explained in the next link.

(XAF): Security Permissions for UI Actions - YouTube

This is so awesome and it has been requested several times in the support center and as always, they are delivering. Xafari had this already but that means and extra license. It is still in CTP but this new security layer will allow developers to prohibit execution of both custom and XAF system Actions in WinForms and ASP.NET applications.

How to port an XAF platform-agnostic module from .NET Framework to .NET Standard 2.0+ | DevExpress Support

No more multi-target. Now we can have our XAF platform-agnostic module completely in .NET Standard 2.0+. As always keep a copy of your csproj before messing with your project.

XAF Windows

WinForms Data Grid - Kanban Board Enhancements (v20.1)

Already have something similar implemented but so great to see it is coming out of the box. This will come really handy in a lot of my apps.

WinForms Data Grid - Summaries by Selection (v20.1)

Another great feature, and really flexible. We can have a mixed mode that when selecting use the summaries by selection and comeback to All when unselected 👏👏👏

WinForms Data Grid and Tree List - Hovered Row Appearance

I love to see these improvements on our WinForms DataGrid, that means we can take advantage of it in our XAF apps. Great work DevExpress, as always :)

WinForms Splash Screen: Fluent UI and Skins - YouTube

The WinForms Splash Screen control is receiving a major facelift in 20.1 and will include two entirely new splash screen design options. The first is a Fluent Splash Screen - a Windows 10-inspired splash screen that features the Acrylic material effect with a partially transparent texture. The second is a Skin-based or Themed Splash Screen – one that auto-adjusts its appearance based on the current applied application skin or theme.

XAF Blazor

FAQ: XAF ASP.NET Core Blazor Server UI (CTP) | DevExpress Support

Every day we are closer to our XAF Blazor Server UI. Here we have common questions you might be asking yourself. Ex: A VB.NET Blazor application cannot be created since this functionality is not supported by Microsoft.

What about concurrent users?

Net Core

.NET Core 3.0+ Support in XAF WinForms Applications | eXpressApp Framework | DevExpress Documentation

What XAF modules are supported in .NET Core 3.0+? Old security system is not neither old Reports Module. What else should I know about XAF in .Net Core?

.NET Standard 2.0 Support for Platform-Agnostic Modules | eXpressApp Framework | DevExpress Documentation

The modules listed in this topic support .NET Standard 2.0 and provide non-visual APIs. You can use these libraries if you create cross-platform non-XAF .NET apps and libraries. No more multi-target, no more black magic. Everywhere .NET Standard runs we are set.

Port an Existing XAF Application to .NET Core 3.0+ | eXpressApp Framework | DevExpress Documentation

Steps to port your XAF WinForms application from .NET Framework to .NET Core. Before starting the migration don't forget to copy and save the current versions of all csproj files. Maybe use a new branch and go for it.

FAQ: Model Editor for .NET Core and .NET Standard (CTP) | DevExpress Support

Nice article about the Model Editor for .NET Core and .NET Standard. Prerequisites, Known Issues, Limitations and more. I have been waiting for this for a long time so let's test it and give some feedback back.
