My team uses Sitecore 6 as content management system and then .Net to interface with Sitecore API. In many of our templates we make use of a Treelist. When adding a new item to the selected items Treelist it automatically puts the item at the bottom of the list.

In some lists they get very large. In most cases end users would like to see these lists sorted descending by a Date field that is part of the templates that can be added as selected to the Treelist.

Programmatically on the .Net side its very easy to handle this using Linq OrderByDescending and all displays great in the site to visitors. What I am trying to figure out is how to get it to display the same in Sitecore Content Editor.

I've not found anything from Google search other than there seems to be a SortBy you can specify in the source but I tried this and can't get it to have any effect.

Has anyone dealt with this before? Again, main goal is to sort items in a Treelist in the Sitecore Content Editor itself.

Thanks for any input anyone has.
