Assign the Spreadsheet Property Editor to a Business Class' Property

In Code

Decorate a business class' property with the EditorAliasAttribute and pass the SpreadsheetPropertyEditor value as the attribute's parameter:

using DevExpress.ExpressApp.Editors;
using DevExpress.Persistent.Base;
using DevExpress.Persistent.BaseImpl;
// ...
private byte[] data;
[EditorAlias(EditorAliases.SpreadsheetPropertyEditor)] 
public byte[] Data { 
    get { return data; }
    set { SetPropertyValue(nameof(Data), ref data, value); }
}

In the Model Editor

Navigate to the Views | <DetailView> | Items | <PropertyEditor> node and set the PropertyEditorType property to DevExpress.ExpressApp.Office.Win.SpreadsheetPropertyEditor or DevExpress.ExpressApp.Office.Web.ASPxSpreadsheetPropertyEditor.

Edit the Document in a Separate Window

Use the Show in popup context menu command to open the document in a new modal window.

In ASP.NET applications, you can edit the document in full-screen mode.
