Generating PDF, reports or any document in MVC is generally the basic requirement in most of the projects. To address this requirement, we can leverage a third party tool “Rotativa” to generate PDF documents. Rotativa is an asp.net library which helps in spawning PDFs from MVC controller. This tool gives us the flexibility to create PDFs directly from views, partial views or URL.
We need to follow certain steps to generate PDF from Rotativa tool:
- Open Visual Studio.
- Select File -> New Project.
- Select ASP.NET MVC 4 Web Application under Templates-> Visual C#->Web->Visual Studio 2012.
4. Select Empty or Internet Application template, and select Razor as the view engine.
5. Add a class in Models folder with SampleModel name.
6. Add a Controller in Controllers folder with SampleController name.
7. Add a strongly typed view to create a view aligned with a particular class or a dynamic view for creating a generalized view.

Sample.cs: Model Class
using System;
using System.Collections.Generic;

using System.Web.Mvc;
namespace RotativaSample.Models
{ public class Sample
{ public int EmpId {get;set;}
public string Name { get;set;}
public string Email {get;set;}
public string Country { get;set;}
}
public List GetSampleDetails() {
List samples = new List();
samples.Add(new SampleModel() { EmpId = 491, Name = “abc”, Email = “abc@gmailcom”, Country = “India” });
samples.Add(new SampleModel() { EmpId = 492, Name = “xyz”, Email = “[email protected]”, Countr y = “India” });
return (samples);
}
}}
Add another view in Views folder with “GetSamples.cshtml” name and add the below code:
@model dynamic
@{
Layout = null;
}
GetSamples
@foreach (var item in Model)
{
}
Employee Id
|
Employee Name
|
|---|---|
@item.EmpI
|
@item.Name
