Generate ID Card in Multi-Column Page by Mail Merge in ASP.NET Word.

Syncfusion® Essential DocIO is a ASP.NET Word library used to create, read, edit, and convert Word documents programmatically without Microsoft Word or interop dependencies. Using this library, you can generate ID cards in a multi-column page using mail merge in a Word document using C#.

To achieve this, design a template document with a two-column layout. Then, perform mail merge using DocIO to populate the content while maintaining the column structure.

Steps to generate ID cards in a multi-column page using mail merge in a Word document:

1. Create a new .NET Core console application project.
2. Install the Syncfusion.DocIO.Net.Core NuGet package as a reference to your project from NuGet.org.
   
   

3. Include the following namespaces in Program.cs file
   C#

using Syncfusion.DocIO.DLS;
using Syncfusion.DocIO; 

4. Use the following code example to generate ID cards in a multi-column page using mail merge in a Word document.
   C#

using (FileStream fileStream = new FileStream(Path.GetFullPath("Template.docx"), FileMode.Open, FileAccess.ReadWrite))
{
   //Loads an existing Word document into DocIO instance.
   using (WordDocument document = new WordDocument(fileStream, FormatType.Automatic))
   {
       //Gets the employee details as IEnumerable collection.
       List<Employee> employeeList = GetEmployees();
       //Creates an instance of MailMergeDataTable by specifying MailMerge group name and IEnumerable collection.
       MailMergeDataTable dataSource = new MailMergeDataTable("Employees", employeeList);
       //Uses the mail merge events handler for image fields.
       document.MailMerge.MergeImageField += new MergeImageFieldEventHandler(MergeField_EmployeeImage);
       //Performs Mail merge.
       document.MailMerge.ExecuteGroup(dataSource);
       //Creates file stream.
       using (FileStream outputStream = new FileStream(Path.GetFullPath("Result.docx"), FileMode.Create, FileAccess.ReadWrite))
       {
           //Saves the Word document to file stream.
           document.Save(outputStream, FormatType.Docx);
       }
   }
}

5. Use the following code example to represents the method that handles MergeImageField event.
   C#

private static void MergeField_EmployeeImage(object sender, MergeImageFieldEventArgs args)
{
   //Binds image from file system during mail merge.
   if (args.FieldName == "Photo")
   {
       string photoFileName = args.FieldValue.ToString();
       //Gets the image from file system.
       FileStream imageStream = new FileStream(Path.GetFullPath(@"Data/" + photoFileName), FileMode.Open, FileAccess.Read);
       args.ImageStream = imageStream;
       //Gets the picture, to be merged for image merge field
       WPicture picture = args.Picture;
       //Resizes the picture
       picture.Height = 90;
       picture.Width = 90;
   }
}

6. Use the following code example to get the employee details to perform mail merge.
   C#

public static List<Employee> GetEmployees()
{
   List<Employee> employees = new List<Employee>();
   employees.Add(new Employee("Nancy", "Smith", "Sales Representative", "505 - 20th Ave. E. Apt. 2A,", "Seattle", "WA", "USA", "Nancy.png"));
   employees.Add(new Employee("Andrew", "Fuller", "Vice President, Sales", "908 W. Capital Way", "Tacoma", "WA", "USA", "Andrew.png"));
   employees.Add(new Employee("Roland", "Mendel", "Sales Representative", "722 Moss Bay Blvd.", "Kirkland", "WA", "USA", "Janet.png"));
   employees.Add(new Employee("Margaret", "Peacock", "Sales Representative", "4110 Old Redmond Rd.", "Redmond", "WA", "USA", "Margaret.png"));
   employees.Add(new Employee("Steven", "Buchanan", "Sales Manager", "14 Garrett Hill", "London", string.Empty, "UK", "Steven.png"));
   return employees;
} 

7. Use the following code example to represents a class to maintain employee details.
   C#

/// <summary>
/// Represents a class to maintain employee details.
/// </summary>
public class Employee
{
   public string FirstName { get; set; }
   public string LastName { get; set; }
   public string Address { get; set; }
   public string City { get; set; }
   public string Region { get; set; }
   public string Country { get; set; }
   public string Title { get; set; }
   public string Photo { get; set; }
   public Employee(string firstName, string lastName, string title, string address, string city, string region, string country, string photoFilePath)
   {
       FirstName = firstName;
       LastName = lastName;
       Title = title;
       Address = address;
       City = city;
       Region = region;
       Country = country;
       Photo = photoFilePath;
   }
}
