Preventing hidden fields from being transferred to Word

Dec 8 2023 12:59 PM

I want to transfer the optionally selected columns in the datagridview to word. The columns I did not select are transferred to Word as empty. I don't want it to appear at all.

My project is working as in the following :

This is the result of my project.

This is exactly what I want.

using System;
using System.Data;
using System.Data.OleDb;
using System.Drawing;
using System.IO;
using System.Windows.Forms;
using Word = Microsoft.Office.Interop.Word;

namespace SinifListesi
{
    public partial class WordeAktar : Form
    {
        public WordeAktar()
        {
            InitializeComponent();
        }
        OleDbConnection conn = new OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source = siniflisteleri25.accdb; Jet OLEDB:Database Password = Fatih2541; Mode = ReadWrite");
        OleDbCommand sorgu;
        OleDbDataReader veriler;


        private void SinifCek()
        {
            try

                {
