This tutorial describes how to use the DevExpress Template Gallery to generate a basic ASP.NET Core application that contains the Document Viewer control.

Use the DevExpress Template Gallery

Follow the steps below to create an ASP.NET Core application with a Document Viewer:

• Ensure that Node.js 10.0 or later with the npm package manager is installed on your computer. Use the node -v and npm -v console commands on 64-bit Windows systems to check package versions (if the package’s version does not match the version you installed, check the PATH environment variable’s value - as there may be a conflict between an x86 and x64 package).

Create a New Project

1. Select FILE | New | Project in the main menu or press CTRL+SHIFT+N to create a new project.

   

2. Select the DevExpress v22.2 Web App Template Gallery, and click Next:

   

3. Specify a project name and location, and click Create:

   

4. In the invoked DevExpress Template Gallery, select Reporting Application in the .NET 6 category.

   

   Select framework version and click Create Project.

5. Set Add Viewer Page to true to add the Document Viewer (the Viewer.cshtml view) to the web application. You can add a Web Document Viewer and a Report Designer to the application.

   

   Use the following Document Viewer settings:

   • Report Storage Name- the server-side report storage‘s class name.
   • Data Binding Mode* - switches between the Expressions and Expressions (Advanced) modes that specify how data is fetched to reports and controls. See Data Binding Modes for more information.

   Click Create Project to apply these settings to the project.

6. After Visual Studio has created the application, right-click the package.json file in Solution Explorer and choose Restore Packages.

   

7. Optional. You can configure the Document Viewer to load a different report when the application starts. Navigate to the Views | Home | Viewer.cshtml file and replace the built-in report name (TestReport in this example) with the name of your report:

   Viewer.cshtml

   @{
       var viewerRender = Html.DevExpress().WebDocumentViewer("DocumentViewer")
           .Height("1000px")
           .Bind("TestReport");
       @viewerRender.RenderHtml()
   }
   

8. Run the project to see the result:
