Namespace: DevExpress.AspNetCore.Reporting.WebDocumentViewer

Assembly: DevExpress.AspNetCore.Reporting.v20.2.dll

NuGet Package: DevExpress.AspNetCore.Reporting

Declaration

C#

public WebDocumentViewerBuilder Bind(
    WebDocumentViewerModel model
)

VB.NET

Public Function Bind(
    model As WebDocumentViewerModel
) As WebDocumentViewerBuilder

Parameters

Name	Type	Description
model	WebDocumentViewerModel	A View Model.

Returns

Type	Description
WebDocumentViewerBuilder	A WebDocumentViewerBuilder object for use in method chaining.

Remarks

The application controller should use the WebDocumentViewerClientSideModelGenerator object to create a View Model. You can call the GetModel method overload to create a report model and pass it to the view.

The advantage of this technique is that it allows you to use an asynchronous task for report creation. You can call the UseAsyncEngine method at application startup to enable asynchronous mode, and use the GetModelAsync method:

HomeController.cs

using DevExpress.AspNetCore.Reporting.WebDocumentViewer;
using DevExpress.XtraReports.Web.WebDocumentViewer;
using Microsoft.AspNetCore.Mvc;
using System.Threading.Tasks;
// ...
    public class HomeController : Controller {        
        public async Task<IActionResult> Index([FromQuery] string reportName = "MainReport") {
            var modelGenerator = new WebDocumentViewerClientSideModelGenerator(HttpContext.RequestServices);
            var model = await modelGenerator.GetModelAsync(reportName, WebDocumentViewerController.DefaultUri);
            return View(model);
        }
    }

Startup.cs

using DevExpress.AspNetCore.Reporting;
using Microsoft.Extensions.DependencyInjection;
    public class Startup {
        // ...
        public void ConfigureServices(IServiceCollection services) {
            // ...
            services.ConfigureReportingServices(configurator => {
                // ...
                configurator.UseAsyncEngine();
            });
        }
        // ...
    }
