In a ListView control, with the View property set to Details, you can create a multi-column output. Sometimes you will want the last column of the ListView to size itself to take up all remaining space. You can do this by setting the column width to the magic value -2.

In the following example, the name of the ListView control is lvSample:

private void Form1_Load(object sender, System.EventArgs e)

private void listView1_Resize(object sender, System.EventArgs e)
    SizeLastColumn((ListView) sender);

private void SizeLastColumn(ListView lv)
    lv.Columns[lv.Columns.Count - 1].Width = -2;

Private Sub Form1_Load(ByVal sender As System.Object, _
    ByVal e As System.EventArgs) Handles MyBase.Load
End Sub

Private Sub ListView1_Resize(ByVal sender As System.Object, _
    ByVal e As System.EventArgs) Handles lvSample.Resize
    SizeLastColumn(CType(sender, ListView))
End Sub

Private Sub SizeLastColumn(ByVal lv As ListView)
    lv.Columns(lv.Columns.Count - 1).Width = -2
End Sub

You can also size a column to its contents. This is especially useful after adding an item to the ListView. For example:

lvSample.Columns[0].Width = -1;

lvSample.Columns(0).Width = -1

If the column width is set to -1, the column is sized to the width of the widest item in it. If the value is set to -2, it has a minimum width of the size of the column header, except for the last column, which takes up all remaining space.
