Welcome to this step-by-step guide on using GroupDocs.Viewer for .NET to render grid lines in your documents. Whether you’re a seasoned developer or a newcomer to the .NET framework, this tutorial will walk you through the process with detailed explanations and easy-to-follow examples.

Prerequisites

Before diving into the tutorial, ensure that you have the following prerequisites in place:

• GroupDocs.Viewer for .NET: Download and install the library from the official website.
• Your Document Directory: Make sure you have a designated directory for your documents, and replace “Your Document Directory” in the provided code snippet with the actual path. Now that you have everything set up, let’s get started.

Import Namespaces

In your .NET project, start by importing the necessary namespaces:

using System;
using System.IO;
using GroupDocs.Viewer.Options;

Step 1: Set up the Document Directory

Begin by specifying the path to your documents directory:

string outputDirectory = "Your Document Directory";

Replace “Your Document Directory” with the actual path where your documents are stored.

Step 2: Define File Path and HTML Output Format

Create a variable to store the file path format for each page and the output HTML format:

string pageFilePathFormat = Path.Combine(outputDirectory, "page_{0}.html");

This line constructs the file path for each page in the specified format.

Step 3: Initialize GroupDocs.Viewer

Instantiate the Viewer class with the document you want to view:

using (Viewer viewer = new Viewer(outputDirectory + "SAMPLE.XLSX"))
{
    // Further steps will be performed within this using block.
}

Ensure to replace “SAMPLE.XLSX” with the name of your actual document.

Step 4: Configure HTML View Options

Set up the HTML view options, specifically enabling the rendering of grid lines:

HtmlViewOptions options = HtmlViewOptions.ForEmbeddedResources(pageFilePathFormat);
options.SpreadsheetOptions.RenderGridLines = true;

This code snippet configures the HTML view options to embed resources and render grid lines for spreadsheet documents.

Step 5: Render Grid Lines

Invoke the View method to render the document with the specified options for pages 1, 2, and 3:

viewer.View(options, 1, 2, 3);

Adjust the page numbers according to your requirements. That’s it! You have successfully rendered grid lines using GroupDocs.Viewer for .NET.
