    Re: how to add item in listview control

    I have a listview in C# with four columns and add an item with a specified directory (i.e. c or other drive). I have done it like this and it seems to work:

    public Form1()

            {

                InitializeComponent();

                listView1.View = View.Details;

                listView1.GridLines = true;

                listView1.FullRowSelect = true;

                      // for adding column in listview 

                listView1.Columns.Add("Index", 60);

                listView1.Columns.Add("File Name", 300);

                listView1.Columns.Add("Size", 100);

                listView1.Columns.Add("Readonly", 70);

                int i = 1;

                  // Get all text files of specified directory to add a listview

                string[] filePaths = Directory.GetFiles(@"D:\\Anupam Mishra" "*.txt",         SearchOption.AllDirectories);

                foreach (var item in filePaths)

                {

                    long len = new FileInfo(item.ToString()).Length;

                    String name = new FileInfo(item.ToString()).Name;

                  // for adding item in listview 

                    ListViewItem _item = new ListViewItem();

                    _item.Text = i.ToString();

                    _item.SubItems.Add(name);

                    _item.SubItems.Add(BytesToString(len));

                    _item.SubItems.Add(filePaths.IsReadOnly.ToString());

                     // adding item in listview

                    listView1.Items.Add(_item);

                    i++;

                }

            }

     

    for checking the file size we create a new function BytesToString(double) as below:

    It returns total size and unit of file size.

     

      static String BytesToString(long byteCount)

            {

                string[] _unit = { "Byte", "KB", "MB", "GB", "TB", "PB", "EB" };

                if (byteCount == 0)

                    return "0" + _unit [0];

                long bytes = Math.Abs(byteCount);

                int place = Convert.ToInt32(Math.Floor(Math.Log(bytes, 1024)));

                double num = Math.Round(bytes / Math.Pow(1024, place), 1);

                return (Math.Sign(byteCount) * num).ToString() + " "+_unit [place];

            }

    It runs where user click on the button and display current selected row data. Code as follow:

    private void button1_Click(object sender, EventArgs e)

            {

                string _filePath = null;

                string Size = null;

                string ro = null;

                try

                {

                  // When we selected any row

                    _filePath = listView1.SelectedItems[0].SubItems[1].Text;

                    Size = listView1.SelectedItems[0].SubItems[2].Text;

                    ro = listView1.SelectedItems[0].SubItems[3].Text;

                    MessageBox.Show(_filePath + ", " + Size + ", " + ro);

                }

                catch (Exception)

                {

                    MessageBox.Show("Please select the atleast one file");

                }

            }
