A few weeks ago, the eXpandFramework released registration support as discussed in How to manage users (register a new user, restore a password, etc.) from the logon form. While users could register, the implementation process was still incomplete it was missing email notification. Thus, this post will discuss the new EmailModule which was made ...

In this post I will provide a discussion on how to apply auditing configurations to your XAF applications, I will use the build-in XAF Audit Trail module and the eXpand Logic module for extending the XAF Application Model. Goal Our goal is to be able to declaratively configure auditing for different scenarios. For example apply an auditing ...

After I posted the Contolling DevExpress XtraGrid Part-2 (Master Detail) I got many requests to speak about how easy will be to make a behaviout conditional so I am going to explain again how ModelArtifact module was build that is based on eXpand logic architecture Is based on the eXpand Logic architecture and more specifically at eXpand ...

This is a sneak peak for eXpand v10 We have control trhough model all of the options of GridView as shown at  Controlling DevExpress AspxGridControl at runtime  eXpand had already a very simple implementation of master detail but did not support many levels. Since that implementation was too old i wrote it almost when I started using ...

This one is the most complex implementation of the logic architecture cause this module is really a facade module. ActionState and ControllerState modules are hosted within it. But the implementation for each one of them as you see in the image bellow really looks alike   In order to control the different in ...

 AdditionalViewControlsProvider is a module that it only knows how to display a given control in a given position . So one could easily define an interface for the parameters needed when this behavior is implemented as public interface IAdditionalViewControlsRule:IConditionalLogicRule {     string Message { get; set; } ...

Say you want to make your rules conditional , meaning that you want your rules to be executed when certain criteria are valid for a given object. That is implemented at eXpand.ExpressApp.ConditionalLogic.dll assembly. I have extend ILogicRule interface like public interface IConditionalLogicRule : ILogicRule {     /// ...

Xaf architecture and especially the model part is great. What it really teach us is how to parameterized our logic/behavior/code and store that parameter in the model in the form of attributes on already existing nodes or on rule nodes see Xaf Validation system or ConditionalEditorState system. eXpand has provided a similar architecture through ...
