How to Easily Add an Adobe Pdf Viewer in Visual Studio 2019 for Your ASP.NET VB.NET Project

Are you struggling to display PDF files on your web page using ASP.NET and VB.NET in Visual Studio 2019? You’re not alone! Many developers often encounter issues when trying to integrate the Adobe PDF viewer into their projects. In this guide, we will break down the steps and solutions to successfully display PDF files on your screen. Let’s dive in!

Understanding the Problem

When working with ASP.NET and VB.NET, displaying a PDF file can sometimes be a challenge. You might add the "Adobe PDF Reader" in your toolbox and attempt to include the "Adobe Acrobat 7.0 Browser Control Type Library," but still find the PDF viewer is missing from your toolbox. This can be frustrating, but fear not! Let’s explore the solutions available to you.

Solution Overview

There are a couple of ways to display PDFs in your ASP.NET VB.NET project, even when the Adobe PDF reader does not show up. Below, we will discuss two primary methods: using an asp:LinkButton and utilizing a third-party library like DevExpress.

Method 1: Using asp:LinkButton

If you do not want to use any external libraries or plugins, you can utilize a simple solution involving an asp:LinkButton. Here's a breakdown of how this works:

Set Up the Link: Create an asp:LinkButton that, when clicked, will open the PDF file in a new tab or window.
