Getting Started with ASP.NET MVC

Starting with v16.4.0.x, if you reference Syncfusion assemblies from trial setup or from the NuGet feed, include a license key in your projects. Refer to this link to learn about registering Syncfusion license key in your ASP.NET MVC application to use Syncfusion components.

Prerequisites

To get started with ASP.NET MVC application, ensure that the following software is installed on the machine.

  • .Net Framework 4.5 and above.
  • ASP.NET MVC 4 or ASP.NET MVC 5
  • Visual Studio

Preparing ASP.NET MVC application

The following steps are used to create ASP.NET MVC application.

Step 1: Create ASP.NET MVC web application with default template project in Visual Studio.

Default Template

Step 2: After creating the project, add the following dependencies to your application by using NuGet Package Manager.

  • Syncfusion.EJ2.MVC5
  • Syncfusion.EJ2.PdfViewer.AspNet.Mvc5

Open the NuGet package manager.

Solution Explorer

Install the Syncfusion.EJ2.MVC5 package to the application.

Nuget Demo

Install the Syncfusion.EJ2.PdfViewer.AspNet.Mvc5 package to the application.

Step 3: Add Syncfusion.EJ2 namespace reference in Web.config

<namespaces>
    <add namespace="Syncfusion.EJ2"/>
    <add namespace="Syncfusion.EJ2.PdfViewer"/>
</namespaces>
<system.web>
    <compilation>
      <assemblies>
        <add assembly="Syncfusion.EJ2, Culture=neutral"/>
        <add assembly="Syncfusion.EJ2.PdfViewer, Culture=neutral"/>
      </assemblies>
    </compilation>
  </system.web>

Step 4: Add client side resource through CDN or local package in the layout page _Layout.cshtml.

{% aspCodeBlock %}

@* Syncfusion Essential JS2 Scripts *@
<script src="https://cdn.syncfusion.com/ej2/dist/ej2.min.js"></script>

{% endaspCodeBlock %}

Step 5: Adding Script Manager in the layout page _Layout.cshtml.

@Html.EJS().ScriptManager()

Step 6: Add the following code to the Index.cshtml view page, which is presented under Views/Home folder, to initialize the PDF Viewer.

razor
PdfViewerController.cs
<div style="height:500px;width:100%;">
    @Html.EJS().PdfViewer("pdfviewer").ServiceUrl(VirtualPathUtility.ToAbsolute("~/PdfViewer/")).Render()
</div>
