Sort by Title in Core Service for Categories

Question

I am using SDL Tridion 2013 SP1 and using the Core Service to retrieve all the categories in the SDL Tridion system. Below is my code:

TaxonomiesFilterData taxFilter = new TaxonomiesFilterData();
taxFilter.SortExpression = "Title";
XElement items = client.GetListXml("tcm:0-10-1", taxFilter);

Here client is a SessionAwareCoreServiceClient client and tcm:0-10-1 is a valid Publication ID

I am able to retrieve all the categories in the publication successfully, however, the issue is that they are not in a Sorted order as I wish to get them in sorted by their title (same as it happens in the CME).

Further, I have even tried using the Item Selector Community extension (created by Bart) but I am also getting the same result (non-sorted list of categories).

Any help will be highly appreciated.

Answer 1

Just use

var items = client.GetList("tcm:0-10-1", taxFilter);

And then

var orderedItems = items.OrderBy(i => i.Title);

Answer 2

I am not sure, if taxFilter.SortExpression = "Title"; works at all. I have tried it with TaxonomiesFilterData and CategoriesFilterData and its not working like above (setting a field name as a sort expression ).

But if you want to use GetListXml not GetList as suggested in anothee answer by @user978511, you can use CategoriesFilterData inplace of TaxonomiesFilterData, as it returns the categories sorted by title by default.

I know its not the best option but could be useful.
