DevExpress的XAF取消分组布局继承类的。 （programmaticaly） [英] Devexpress xaf ungroup layout of inherited class. (programmaticaly)

问题描述

我使用的DevExpress XAF创建一个多平台的应用程序。我有类'commonFields，其中包含常见的域CREATION_DATE，CREATED_BY等所有其他类继承此类。我的问题是，在的DetailView布局，共同字段显示标有commonFields在一组。

I am using devexpress xaf to create a multi platform app. I have class 'commonFields' which contains common fields "creation_date, created_by" etc. all other classes inherit from this class. My problem is that, in detailView layout, common fields are displayed in a group labled commonFields.

我知道它可以使用模型编辑器来解决，我只需右键点击在组，然后选择取消组合，但如果我有让说，50多桌，我将不得不从GUI单独编辑所有的布局。

I know it can be solved using the model editor where I can simply right click over the group and choose ungroup, but if I have lets say more than 50 tables I will have to edit all the layouts individually from the GUI.

我想知道有任何其他方式，方法或一些属性我可以添加到它将显示在同一组继承字段类

I wanted to know if there is any other way, a method or some attribute I can add to the class which will display inherited fields in the same group.

推荐答案

当然，你可以通过代码做到这一点。下面是DevExpress的文档：扩展和定制代码中中的应用模型

Sure you can do it via code. Here is the DevExpress documentation: Extend and Customize the Application Model in Code.

您需要提供自己的 ModelNodesGeneratorUpdater 的详细视图的XAF模型的一部分。它应该是这个样子：

You need to provide your own ModelNodesGeneratorUpdater for the detail views part of the XAF model. It should look something like this:

public class MyDetailViewGeneratorUpdater : ModelNodesGeneratorUpdater<ModelDetailViewLayoutNodesGenerator> 
{
    public override void UpdateNode(ModelNode node) 
    {
        IModelDetailViewLayout layout = node as IModelDetailViewLayout;
        IModelDetailView detailView = (IModelDetailView)layout.Parent;
        if (!XafTypesInfo.Instance.FindTypeInfo(typeof(MyBase)).IsAssignableFrom(detailView.ModelClass.TypeInfo))   return;
        foreach (IModelDetailViewLayoutElement element in layout)
            UpdateLayoutItems(element, detailView.Items, XafTypesInfo.Instance.FindTypeInfo(typeof(MyBase)).FindMember("Description"));
    }

    private void UpdateLayoutItems(IModelDetailViewLayoutElement element, IModelDetailViewItems items, IMemberInfo member) {
        IModelLayoutItem item = element as IModelLayoutItem;
        IModelLayoutGroup group = element as IModelLayoutGroup;
        if(group != null){
            foreach(IModelDetailViewLayoutElement element1 in group)
            UpdateLayoutItems(element1, items, member);
        }
        else if (item != null) {
            RemoveFromGroup(item); // you just need to code this bit of magic
        }
    }
}

$ B的这个位码$ b

不要忘了在模块中注册您的更新：

Don't forget to register your updater in the module:

public override void AddGeneratorUpdaters(ModelNodesGeneratorUpdaters updaters)
{
    base.AddGeneratorUpdaters(updaters);
    updaters.Add(new MyDetailViewGeneratorUpdater());
}
