DetailView.ViewEditMode Property

Specifies a mode of displaying a Detail View in ASP.NET Web Forms applications.

Namespace: DevExpress.ExpressApp

Assembly: DevExpress.ExpressApp.v23.2.dll

NuGet Package: DevExpress.ExpressApp

Declaration

C#

public ViewEditMode ViewEditMode { get; set; }

VB.NET

Public Property ViewEditMode As ViewEditMode

Property Value

Type	Description
ViewEditMode	A ViewEditMode enumeration value that represents the current Detail View’s display mode.

Available values:

Name	Description
View	An XAF element that supports the View-Edit mode is displayed in the read-only mode in ASP.NET Web Forms applications.
Edit	An XAF element that supports the View-Edit mode is displayed in the editable mode in ASP.NET Web Forms applications.

Remarks

Use this property to specify the mode for displaying the current Detail View in ASP.NET Web Forms applications. The following values are available:

• Edit

  The Detail View is available for editing.

• View

  The Detail View can be viewed only.

By default, a Detail View is displayed in the View mode when being invoked from a List View. To switch to the Edit mode, use the SwitchToEditMode Action. To save changes and switch the Detail View back to the View mode, use the SaveAndClose Action.

You can change this default behavior as described in the How to: Display a Detail View Directly in Edit Mode in ASP.NET Web Forms Applications topic.

The example below demonstrates how to make all Detail Views in an application read-only.

C#

using DevExpress.ExpressApp;
using DevExpress.ExpressApp.Editors;
// ...
public class MakeDetailViewsReadOnlyController : ViewController<DetailView> {
    protected override void OnActivated() {
        base.OnActivated();
        View.ViewEditMode = ViewEditMode.View;
    }
}

VB.NET

Imports DevExpress.ExpressApp
Imports DevExpress.ExpressApp.Editors

Public Class MakeDetailViewsReadOnlyController
    Inherits ViewController(Of DetailView)
    Protected Overrides Sub OnActivated()
        MyBase.OnActivated()
        View.ViewEditMode = ViewEditMode.View
    End Sub
End Class
