XafApplication.CreateDetailView(IObjectSpace, String, Boolean, Object) Method

Creates a Detail View for the specified object based on the information from the Application Model‘s Views | DetailView node specified by the detailViewID parameter.

Namespace: DevExpress.ExpressApp

Assembly: DevExpress.ExpressApp.v21.1.dll


public DetailView CreateDetailView(
    IObjectSpace objectSpace,
    string detailViewID,
    bool isRoot,
    object obj


Name Type Description
objectSpace IObjectSpace

An IObjectSpace object which is used to work with the new Detail View’s DetailView.CurrentObject. This object is assigned to the View.ObjectSpace property.

detailViewID String

A string that represents an identifier of the Application Model node that serves as an information source for creating a new Detail View.

isRoot Boolean

true, if the created Detail View is independent and owns the Object Space passed using the objectSpace parameter; false, if the created Detail View is nested to another root View that owns the Object Space. This value is assigned to the View.IsRoot property.

obj Object

An object which is represented by the new Detail View. This object is assigned to the DetailView.CurrentObject property.


Type Description

A Detail View that represents the object passed as the obj parameter.


Use this method to create and initialize a Detail View according to values passed as parameters.

The detailViewID parameter should be equal the Id property of an existing IModelDetailView node from the Application Model’s Views node. If your Application Model contains several DetailView models of a certain business class, use this parameter to define which model should be used for the created View.

Pass true to the isRoot parameter if the new View owns the Object Space passed to the objectSpace parameter. If this Object Space already belongs to another View, pass false. Note that certain Controllers and Actions are deactivated in this case. See View.IsRoot for additional information. To avoid this, use the XafApplication.CreateObjectSpace or XafApplication.CreateNestedObjectSpace method to create a new Object Space, and pass this Object Space to the objectSpace parameter.

The object specified in the obj parameter should belong to the Object Space specified in the objectSpace parameter. To pass an object from another Object Space to this Object Space, use the IObjectSpace.GetObject method.


Do not use another View’s View.ObjectSpace for the creation of a new root View in it. Instead, create a new Object Space using the XafApplication.CreateObjectSpace method for the new root View.

The example below demonstrates how to open an object’s Detail View via a PopupWindowShowAction.

using System;
using DevExpress.ExpressApp;
using DevExpress.ExpressApp.Actions;
using DevExpress.Persistent.Base;
using DevExpress.Persistent.BaseImpl;
// ...
public class ShowDetailViewController : ObjectViewController<ListView, Person> {
    public ShowDetailViewController() {
        PopupWindowShowAction showDetailViewAction = new PopupWindowShowAction(
            this, "ShowDetailView", PredefinedCategory.Edit);
        showDetailViewAction.SelectionDependencyType = SelectionDependencyType.RequireSingleObject;
        showDetailViewAction.CustomizePopupWindowParams += ShowDetailViewAction_CustomizePopupWindowParams;
    private void ShowDetailViewAction_CustomizePopupWindowParams(
        object sender, CustomizePopupWindowParamsEventArgs e) {
        IObjectSpace objectSpace = Application.CreateObjectSpace(typeof(Person));
        Object currentObject = objectSpace.GetObject(View.CurrentObject);
        if(currentObject != null) {
            Type objectType = currentObject.GetType();
            string detailViewId = Application.GetDetailViewId(objectType);
            e.View = Application.CreateDetailView(objectSpace, detailViewId, true, currentObject);
        else {
