DevExpress offers a great installer for their components and frameworks. But if you work in a continuous integration environment or have to deal with different versions of the components NuGet packages are the better way to deploy and version-control  dependencies. This project contains .nuspec files for  DevExpress WinForms, Web and XAF ...

Using the same approach we did for controlling DevExpress XtraGrid at runtime.

When I first met DevExpress I was amazed by their XtraGrid control. What a configuration monster!. Xaf exposes some of the configuration but not all. eXpand allows you to control all configurations of XtraGridControl per view as shown bellow

eXpand has a new module that make its easy to protect selected members from selected object instances.

.NET provides a lot of ways to collaborate between systems. All of them are based on data serialization.

WorldCreator a module designed to work with Xaf can really work without it!!!! Suppose you have a non xaf application and you use Xpo as your dataLayer and you want dynamic types then WorldCreator can for sure help you. You just reference WorldCreator and eXpand.BaseImpl assemblies and use an approach similar to the specs bellow [Test] ...

 The Problem 1 A common requirement in any OOP application is the ability to filter a listview of objects according to their childs in whatever level they belong. eXpand can solve the above by the use of propertypath filters.

That means that you can define dynamic types at runtime through a UI (xaf views) save them in the database and let your imagination free !!! Installation Very simple you just register the selected assemblies ...

Maybe not with the build in modules and not exactly before lunch but the difference between traditional programming and Xafing is really great. I am going to continue my posts on WorldCreator module and going to inform you about the progress up to here. New persistent objects have been designed and added to eXpand.BaseImpl assembly in order ...

Dynamic Types is one of the most wanted feature in any framework. Luckily me I met Emilio DabDoub of Signia software and one of the Coordinators of XERP project and he hire me to port an old code that he had that could provide that feature and much more into xaf. Also he agreed to publish that module into eXpand. Technorati Tags: ...

The bad first, until we manage to have full continuous integration in order eXpand new features to be immediately available (nightly builds) we are not going to make any more releases. eXpand release policy will be the same as DevExpress that is we make a release exactly after DevExpress And now for the good. ...

For this question don’t we all of us spend a lot of time ? But I think it is allowed to use a trick to spend our selves that time. Add to your model to attributes NotifyIcon, MinimizeOnClose. Since I am using Xaf I am going to present that with it but the code should be very similar to any other windows application so here are our attributes ...
