Below is an example to guide you through the process: Load Data from Text File to DataGridView Modify Data in DataGridView Save Modified Data Back to Text File Here's a sample implementation in C#: using System; using System.Data; using System.IO; using System.Linq; using System.Windows.Forms; public partial class Form1 : Form { private string filePath; public Form1() { InitializeComponent(); } private void btnLoadFile_Click(object sender EventArgs e) { OpenFileDialog openFileDialog = new OpenFileDialog(); openFileDialog.Filter = Text Files (*.txt)|*.txt|All Files (*.*)|*.*; if (openFileDialog.ShowDialog() == DialogResult.OK) { filePath = openFileDialog.FileName; DataTable dataTable = new DataTable(); string[] lines = File.ReadAllLines(filePath); if (lines.Length > 0) { // Create columns string[] headerLabels = lines[0].Split(''); foreach (string headerWord in headerLabels) { dataTable.Columns.Add(new DataColumn(headerWord)); } // Adding Rows for (int i = 1; i () .Select(column => column.ColumnName) .ToArray(); lines[0] = string.Join( columnNames); // Get the Rows Data for (int i = 0; i field.ToString()) .ToArray(); lines[i + 1] = string.Join( fields); } File.WriteAllLines(filePath lines); MessageBox.Show(File saved successfully! Success MessageBoxButtons.OK MessageBoxIcon.Information); } else { MessageBox.Show(No file path specified.
