Sorting a ListView or TreeView by number and text

Posted on 2004-09-14
Last Modified: 2008-02-01
 I've for a listview and a treeview control on a form that I want to sort by number and text.  For example, it should sort this way: 1, 2, 3, 9, 10, 11, 99, 100, 101, Alpha, Beta, etc...  instead of 1, 10, 100, 101, 11, 2, 3, 9, Alpha, Beta, etc.  How can I solve this problem in both controls?

  Also, I'd like to be able to sort the TreeView by group/detail (the way that windows sorts folders).  How can I implement this?

  This is something I'd like to get answered quickly, so 500 points.  Thanks!

add column click event by

private void ColumnClick(object o, ColumnClickEventArgs e){
           // Set the ListViewItemSorter property to a new ListViewItemComparer object.
         this.listView1.ListViewItemSorter = new ListViewItemComparer(e.Column);
           // Call the sort method to manually sort the column based on the ListViewItemComparer implementation.

or you just want call sort by yourself

this.listView1.ListViewItemSorter = new ListViewItemComparer(e.Column);

write a ItemCompareer class to implement IComparer

class ListViewItemComparer : IComparer {
      private int col;
      public ListViewItemComparer() {
      public ListViewItemComparer(int column) {
      public int Compare(object x, object y)
          string valuex,valuey;
          int res;


          return res;

Thanks both of you.  It looks like I need to write a class that implements IComparer and then assign it to the listviewitemsorter.  I assume I can do the same for a treeview (although I haven't had time to do this coding yet).  Thanks!
