XafApplication.CreateDetailView(IObjectSpace, Object, Boolean) Method

Creates a DetailView for the specified object and initializes its properties.

Namespace: DevExpress.ExpressApp

Assembly: DevExpress.ExpressApp.v19.1.dll

Declaration

public DetailView CreateDetailView(
    IObjectSpace objectSpace,
    object obj,
    bool isRoot
)
Public Function CreateDetailView(
    objectSpace As IObjectSpace,
    obj As Object,
    isRoot As Boolean
) As DetailView

Parameters

Name Type Description
objectSpace IObjectSpace

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

obj Object

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

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.

Returns

Type Description
DetailView

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

Remarks

Use this method to create a Detail View for the object specified by the obj parameter. The information on the created Detail View is taken from the Application Model' node specified by the IModelClass.DefaultDetailView property of the corresponding IModelClass node.

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.

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 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) {
            e.View = Application.CreateDetailView(objectSpace, currentObject, true);
        }
        else {
            objectSpace.Dispose();
        }
    }
}
