Hi Raskesh. Here is a solution that may provide you ideas and inspiration: Application Start : Getting the Data Text File File Read and Data Display Code that makes it all happen: using System.Data; using System.Data.SqlClient; using System.Drawing; using System.Linq; using System.Text; using System.Threading.Tasks; using System.Windows.Forms; using System.IO; namespace Sandbox2 { public partial class MyMainForm : Form { public MyMainForm() { InitializeComponent(); } private void MyMainForm_Load( object sender, EventArgs e) { SetupListView(); } private void SetupListView() { lvwFileContent.Columns.Clear(); lvwFileContent.Columns.Add( "Col1" , 75, HorizontalAlignment.Left); lvwFileContent.Columns.Add( "Col2" , 75, HorizontalAlignment.Left); lvwFileContent.Columns.Add( "Col3" , 75, HorizontalAlignment.Left); lvwFileContent.Columns.Add( "Col4" , 75, HorizontalAlignment.Left); lvwFileContent.Columns.Add( "Col5" , 75, HorizontalAlignment.Left); lvwFileContent.Columns.Add( "Col6" , 75, HorizontalAlignment.Left); lvwFileContent.Columns.Add( "Col7" , 75, HorizontalAlignment.Left); } private void btnGo_Click( object sender, EventArgs e) { // StreamReader best suited for text files StreamReader fileReader = null ; // Open File Dialog provides the means get the file path OpenFileDialog ofd = new OpenFileDialog(); ofd.InitialDirectory = @ "C:" ; ofd.Filter = "Text Files (*.txt)|*.txt|All files (*.*)|*.*" ; ofd.Multiselect = false ; // show file dialog if (ofd.ShowDialog() == DialogResult.OK) { try { // make sure you a file path value if (ofd.FileName != null ) { string filePath = ofd.FileName; // get your StreamReader ready to work // by opening the file fileReader = File.OpenText(filePath); // using the StreamReader // atuo disposing of resources after use using (fileReader) { // loop until you get to the end of the stream // then stop while (fileReader.EndOfStream== false ) { // get the first line in the text file string line = fileReader.ReadLine(); // divide the line into parts // each part will be a value in a column string [] elements = line.Split( ' ' ); // get a loop counter so we know when to create // listviewitem vs listviewitem.subitem int loop = 0; // create listviewitem ListViewItem i = new ListViewItem(); // go through all the parts one at a time foreach ( string element in elements) { // discard anything that is white space string value = element.Trim(); if (value.Length > 0) { // populate the listivewitem if (loop == 0) { i.Text = value; } else { // create and populate a listviewitem subitem ListViewItem.ListViewSubItem s = new ListViewItem.ListViewSubItem(); s.Text = value; i.SubItems.Add(s); } } // advance the loop count so that // additional foreach loops create // listviewitem subitems loop++; } // add the final listviewitem // to the listview control lvwFileContent.Items.Add(i); } } } } catch (Exception ex) { MessageBox.Show($ "Error: Awwww.. Nutz! Something's wrong! 
 Check it out: {ex.Message }" ); } } } } } Hope this helped you
