ModelViewInheritance

About

The ModuleViewInheritance changes the default Model View generation without coding.

Details

This is a platform agnostic module that extends the model views nodes with the IModelObjectViewMergedDifferences interface to allow model view differences composition.

We want to change the default Model View generation without coding, using the XAF ModelEditor Traditionally: Doing such a complex task without building a similar functionality is not possible. You need an engine that will generate model layers out of user predefined rules. You need to have tests and EasyTest for it. In this case that eye cannot do it. Xpand.XAF.Modules Solution: The cross platform Xpand.XAF.Modules.ModuleViewInheritance module reprograms the default design-time model view generation to respect existing view model differences. In the next screencast:

1. First we extend the model with the GridView component using the Xpand.XAF.Modules.ModelMapper.
2. Then, we used the CloneView package to clone the BaseObject_ListView as a CommonGridView_ListView.
3. Next, the Xpand.XAF.Modules.Reactive WhenGeneratingModelNodes is used to assign the CommonGridView_ListView as a base view.
4. Finally, we modify the CopyToClipBoard value on the CommonGridView_ListView and check that is reflected appropriately on the Customer_ListView.

v1.1.39 #471. Adds the DeepMerge attribute which if enable the module will recourse and merge the source view differences.

Examples

Bellow are a few examples of how we use the module in eXpandFramework.

to derive a version with Remember Me support as below:

The next WorldCreatormodified version of PersistentMemberInfo:

is used to derive a version for the PersistentCoreTypeMemberInfo like:

and in addition one for the PersistentCollectionMemberInfo

Installation

1. First you need the nuget package so issue this command to the VS Nuget package console

   Install-Package Xpand.XAF.Modules.ModelViewInheritance.

   The above only references the dependencies and nexts steps are mandatory.

2. Ways to Register a Module or simply add the next call to your module constructor

   RequiredModuleTypes.Add(typeof(Xpand.XAF.Modules.ModelViewInheritanceModule));

Versioning

The module is not bound to DevExpress versioning, which means you can use the latest version with your old DevExpress projects Read more.

The module follows the Nuget Version Basics.

Issues-Debugging-Troubleshooting

To Step in the source code you need to enable Source Server support in your Visual Studio/Tools/Options/Debugging/Enable Source Server Support. See also How to boost your DevExpress Debugging Experience.

If the package is installed in a way that you do not have access to uninstall it, then you can unload it with the next call at the constructor of your module.

Xpand.XAF.Modules.Reactive.ReactiveModuleBase.Unload(typeof(Xpand.XAF.Modules.ModelViewInheritance.ModelViewInheritanceModule))

The module is tested on Azure for each build with these tests. All Tests run as per our Compatibility Matrix
