Sorry  don t have enough rep  or would have commented on CraigTP s answer   I found the solution from the 1st link - C  Editable ListView  quite easy to use  The general idea is to    identify the SubItem that was selected and overlay a TextBox with the SubItem s text over the SubItem give this TextBox focus change SubItem s text to that of TextBox s when TextBox loses focus   What a workaround for a seemingly simple operation  -

If you re looking for  in-place  editing of a ListView s contents  specifically the subitems of a ListView in details view mode   you ll need to implement this yourself  or use a third-party control   By default  the best you can achieve with a  standard  ListView is to set it s LabelEdit property to true to allow the user to edit the text of the first column of the ListView  assuming you want to allow a free-format text edit    Some examples  including full source-code  of customized ListView s that allow  in-place  editing of sub-items are   C  Editable ListView In-place editing of ListView subitems

I use a hidden textbox to edit all the listview items subitems  The only problem is that the textbox needs to disappear as soon as any event takes place outside the textbox and the listview doesn t trigger the scroll event so if you scroll the listview the textbox will still be visible  To bypass this problem I created the Scroll event with this overrided listview   Here is my code  I constantly reuse it so it might be help for someone   ListViewItem ListViewSubItem SelectedLSI  private void listView2 MouseUp object sender  MouseEventArgs e        ListViewHitTestInfo i   listView2 HitTest e X  e Y       SelectedLSI   i SubItem      if  SelectedLSI    null          return       int border   0      switch  listView2 BorderStyle                case BorderStyle FixedSingle              border   1              break          case BorderStyle Fixed3D              border   2              break             int CellWidth   SelectedLSI Bounds Width      int CellHeight   SelectedLSI Bounds Height      int CellLeft   border   listView2 Left   i SubItem Bounds Left      int CellTop  listView2 Top   i SubItem Bounds Top         First Column     if  i SubItem    i Item SubItems 0           CellWidth   listView2 Columns 0  Width       TxtEdit Location   new Point CellLeft  CellTop       TxtEdit Size   new Size CellWidth  CellHeight       TxtEdit Visible   true      TxtEdit BringToFront        TxtEdit Text   i SubItem Text      TxtEdit Select        TxtEdit SelectAll      private void listView2 MouseDown object sender  MouseEventArgs e        HideTextEditor      private void listView2 Scroll object sender  EventArgs e        HideTextEditor      private void TxtEdit Leave object sender  EventArgs e        HideTextEditor      private void TxtEdit KeyUp object sender  KeyEventArgs e        if  e KeyCode    Keys Enter    e KeyCode    Keys Return          HideTextEditor      private void HideTextEditor         TxtEdit Visible   false      if  SelectedLSI    null          SelectedLSI Text   TxtEdit Text      SelectedLSI   null      TxtEdit Text
