Sorting a dropdown list

[Morten]

Hi!

I've created a webform with a dropdown to which I've added some static
items. I'm adding some extra items in my code. I'd like to sort the items
after I've finished adding my new items. Can someone provide an example of
how to do this?

Thanks in advance for your help.

First of all, keep in mind that sorting the items will change each item's index. Make sure this won't cause any problems in your code.

The most straight-forward approach is to copy the items to an array, sort them, clear the original item list, and copy the sorted items back into the drop down list's items collection.

object[] SortedItems = new object[ddlMyList.Items.Count];
for (int i = 0; i < SortedItems.Length; i++)
{
SortedItems = cbTest.Items;
}
Array.Sort(SortedItems);
ddlMyList.Items.Clear();
ddlMyList.Items.AddRange(SortedItems);
