It is also worth noting that ListView may not display as expected without first changing the property   myListView View   View Details     or View List   For me Visual Studio seems to default it to View LargeIcon for some reason so nothing appears until it is changed   Complete code to show a single column in a ListView and allow space for a vertical scroll bar   lisSerials Items Clear    lisSerials View   View Details  lisSerials FullRowSelect   true      add column if not already present if lisSerials Columns Count  0        int vw   SystemInformation VerticalScrollBarWidth      lisSerials Columns Add  Serial Numbers   lisSerials Width-vw-5      foreach  string s in stringArray        ListViewItem lvi   new ListViewItem new string     s         lisSerials Items Add lvi

You gave the answer  -2 will autosize the column to the length of the text in the column header  -1 will autosize to the longest item in the column  All according to MSDN  Note though that in the case of -1  you will need to set the column width after adding the item s   So if you add a new item  you will also need to assign the width property of the column  or columns  that you want to autosize according to data in ListView control

I believe the author was looking for an equivalent method via the IDE that would generate the code behind and make sure all parameters were in place  etc  Found this from MS   Creating Event Handlers on the Windows Forms Designer  Coming from a VB background myself  this is what I was looking for  here is the brief version for the click adverse         Click the form or control that you want to create an event handler for     In the Properties window  click the Events button     In the list of available events  click the event that you want to create an  event handler for     In the box to the right of the event name  type the name of the handler and press ENTER

I made a program that cleared and refilled my listview multiple times  For some reason whenever I added columns with width   -2 I encountered a problem with the first column being way too long  What I did to fix this was create this method   private void ResizeListViewColumns ListView lv        foreach ColumnHeader column in lv Columns                column Width   -2            The great thing about this method is that you can pretty much put this anywhere to resize all your columns  Just pass in your ListView

This solution will first resize the columns based on column data  if the resized width is smaller than header size  it will resize columns to at least fit the header  This is a pretty ugly solution  but it works   lstContacts AutoResizeColumns ColumnHeaderAutoResizeStyle ColumnContent   colFirstName Width    colFirstName Width  lt  60   60   colFirstName Width   colLastName Width    colLastName Width  lt  61   61   colLastName Width   colPhoneNumber Width    colPhoneNumber Width  lt  81   81   colPhoneNumber Width   colEmail Width    colEmail Width  lt  40   40   colEmail Width     lstContacts is the ListView  colFirstName is a column  where 60 is the width required to fit the title  Etc
