I didn t see anyone answer this correctly   So I m posting it here   In order to get columns to show up you need to specify the following line   lvRegAnimals View   View Details    And then add your columns after that   lvRegAnimals Columns Add  Id   -2  HorizontalAlignment Left   lvRegAnimals Columns Add  Name   -2  HorizontalAlignment Left   lvRegAnimals Columns Add  Age   -2  HorizontalAlignment Left     Hope this helps anyone else looking for this answer in the future

Your first problem is that you are passing -3 to the 2nd parameter of Columns Add  It needs to be -2 for it to auto-size the column  Source  http   msdn microsoft com en-us library system windows forms listview columns aspx  look at the comments on the code example at the bottom   private void initListView            Add columns     lvRegAnimals Columns Add  Id   -2 HorizontalAlignment Left       lvRegAnimals Columns Add  Name   -2  HorizontalAlignment Left       lvRegAnimals Columns Add  Age   -2  HorizontalAlignment Left       You can also use the other overload  Add string   E g    lvRegAnimals Columns Add  Id    lvRegAnimals Columns Add  Name    lvRegAnimals Columns Add  Age      Reference for more overloads  http   msdn microsoft com en-us library system windows forms listview columnheadercollection aspx  Second  to add items to the ListView  you need to create instances of ListViewItem and add them to the listView s Items collection  You will need to use the string   constructor    var item1   new ListViewItem new     id123    Tom    24     var item2   new ListViewItem new    person Id  person Name  person Age    lvRegAnimals Items Add item1   lvRegAnimals Items Add item2     You can also store objects in the item s Tag property    item2 Tag   person    And then you can extract it  var person   item2 Tag as Person    Let me know if you have any questions and I hope this helps
