Sorting a Dropdownlist!!

by Electronic Screw

Hi,
Today while workin on a project, i came across a situation where i need to sort the item in a dropdownlist. Unfortunately, there is no sort method available to the Dropdownlist and other ListItem containers. So i need to write it of my own, the functionality to sort the items. Here is code for you, if any needs!
-- Write these 2 classes in any of your class file.
-- Usage General.SortDropDownList(dropdownlist);

1        public class General {
2            public static void SortDropDownList(DropDownList ddlList) {
3                ArrayList arl = null;
4                if (ddlList.Items.Count > 0) {
5                    arl = new ArrayList(ddlList.Items.Count);
6                    foreach (ListItem li in ddlList.Items) {
7                        arl.Add(li);
8                    }
9                }
10               arl.Sort(new ListItemComparer());
11               ddlList.Items.Clear();
12               for (int i = 0; i < arl.Count; i++) {
13                   ddlList.Items.Add(arl[i].ToString());
14               }
15           }
16       }
17      
18       public class ListItemComparer : IComparer {
19           #region IComparer Members
20           public int Compare(object x, object y) {
21               ListItem lix = (ListItem)x;
22               ListItem liy = (ListItem)y;
23               CaseInsensitiveComparer c = new CaseInsensitiveComparer();
24               return c.Compare(lix.Text, liy.Text);
25           }
26           #endregion
27       }

Thanks
