<p>solution may depend on the way the collection is used. load once? many inserts and deletes? ... the time you have to switch from one sort to another ... and the size of the collection ...</p>
<p>you could</p>
<p>- store the actual collection to a TMemoryStream,</p>
<p>- destroy the collection,</p>
<p>- Load then a new collect to be sort with different method ...</p>

<br /> Ah, clever -- create a Compare that switches based on what I tell it to do. I like that, but as far as I can tell there's no way to tell a TSortedCollection to "resort" -- it's kept sorted only through inserts and deletes.<span><span style="color: #888888;"><br /></span></span></blockquote>

You (or the user) will never need to resotre the first order? I am asking because you could as well simply create one SortedCollection for each sort order and systematically insert each item in all those collections. The overhead would be in the initial loading, but then switching would be instantaneous. <br />
