DocumentOperationService Class

Allows you to perform a custom operation initiated on the client.

Namespace : DevExpress.XtraReports.Web.WebDocumentViewer

Assembly : DevExpress.XtraReports.v25.2.Web.dll

NuGet Package : DevExpress.Web.Reporting.Common

Declaration

C#
VB.NET

csharp

public class DocumentOperationService

Public Class DocumentOperationService

Remarks

You can call the following method on the client side to initiate a custom operation:

ASP.NET Web Forms & MVC	ASP.NET Core & JS Frameworks
ASPxClientWebDocumentViewer.PerformCustomDocumentOperation	JSReportViewer.PerformCustomDocumentOperation

On the server, you should create a DocumentOperationService class descendant, and override its DocumentOperationService.CanPerformOperation method to define which operations are permitted and the DocumentOperationService.PerformOperation method to perform the operation.

You should register the DocumentOperationService class descendant (the CustomDocumentOperationService class in the following code snippets) at application startup:

ASP.NET Core

Program.cs

csharp

using DevExpress.XtraReports.Web.WebDocumentViewer;

var builder = WebApplication.CreateBuilder(args);

builder.Services.AddDevExpressControls();
builder.Services.AddScoped<DocumentOperationService, CustomDocumentOperationService>();

var app = builder.Build();

ASP.NET MVC

Global.asax

csharp

using DevExpress.XtraReports.Web.WebDocumentViewer;
// ...
public class MvcApplication : System.Web.HttpApplication {
    protected void Application_Start() {
        // ...
        DefaultWebDocumentViewerContainer.Register<DocumentOperationService, Services.CustomDocumentOperationService>();
        // ...
        MVCxWebDocumentViewer.StaticInitialize();
        // ...
    }
    // ...
}

ASP.NET Web Forms

Global.asax

csharp

using DevExpress.XtraReports.Web.WebDocumentViewer;
// ...
void Application_Start(object sender, EventArgs e) 
{
..//.
DefaultWebDocumentViewerContainer.Register<DocumentOperationService, CustomDocumentOperationService>();
//...
ASPxWebDocumentViewer.StaticInitialize();
}
