Introduction

In the realm of document visualization, GroupDocs.Viewer for .NET stands tall as a robust tool that facilitates seamless rendering of various document formats. One intriguing capability is the ability to reveal hidden columns and rows within spreadsheets. In this tutorial, we’ll delve into the steps to unlock this feature and unleash the potential of your data.

Prerequisites

Before embarking on this journey, ensure you have the following prerequisites in place:

  • GroupDocs.Viewer for .NET: Make sure you have the latest version installed. If not, you can download it from the official website.
  • Document File: Prepare a sample document in a spreadsheet format (e.g., SAMPLE.XLSX) to experiment with hidden columns and rows.
  • Development Environment: Set up a working environment, preferably using Visual Studio or any other suitable IDE for .NET development.

Import Namespaces

In your .NET project, import the necessary namespaces to leverage GroupDocs.Viewer functionalities effectively:

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

Step 1: Set up Output Directory

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

Define the output directory where the rendered HTML pages will be stored. Adjust the file path format accordingly.

Step 2: Initialize Viewer and Configure Options

using (Viewer viewer = new Viewer("SAMPLE.XLSX"))
{
    HtmlViewOptions options = HtmlViewOptions.ForEmbeddedResources(pageFilePathFormat);
    options.SpreadsheetOptions.RenderHiddenColumns = true;
    options.SpreadsheetOptions.RenderHiddenRows = true;

Create a Viewer instance by providing the path to your spreadsheet document. Configure HTML view options to embed resources and enable the rendering of hidden columns and rows.

Step 3: Execute Rendering Process

    viewer.View(options);
}

Invoke the View method on the viewer object, passing the configured options. This initiates the rendering process.

Step 4: Check the Output

Console.WriteLine($"\nSource document rendered successfully.\nCheck output in {outputDirectory}.");

Verify the successful rendering of the source document and locate the output in the specified directory.

Conclusion

Unlocking hidden columns and rows in your spreadsheets becomes a breeze with GroupDocs.Viewer for .NET. This tutorial has equipped you with the essential steps to reveal concealed data, providing a more comprehensive view of your documents.
