Hi,

protected IQueryable<Event> eventsList;

protected List<Guid> classifList = new List<Guid>();

private void GetThemeList(IQueryable<Event> eventsList)

foreach (Event eI in eventsList)

AddToClassifList(eI.GetValue<TrackedList<Guid>>(catTheme));

private void AddToClassifList(TrackedList<Guid> listId)

if (listId != null)

foreach (Guid taxaId in listId)

if (taxaId != Guid.Empty && !classifList.Contains<Guid>(taxaId))

classifList.Add(taxaId);



"catTheme"

is your own hierarchical category.

Hi Nicolas,
I did not understand what you said.I am new to Sitefinity.
What do you mean by "catTheme" is your own hierarchical category."

My requirement is..,

I created an event "Event 1" and created a category "Category 1" for this event.
Now I want to load this "Category 1" to a drop down list to filter events.

how can I do this?can you please help me ?

Hi,

you create "Category 1" into Categories on backend ? Or Have you created a Hierarchical Classification on your own and put it into ?

If you use standard Categories :

private void GetThemeList(IQueryable<Event> eventsList)

foreach (Event eI in eventsList)

AddToClassifList(eI.GetValue<TrackedList<Guid>>("Categories"));

In my example, you have to fill "eventsList" by your created events. And Call method GetThemeList, the "classifList" will be filled by classifications GUID used on your events.

If you want it in a comboBox it'll be more easier to transform "List<Guid> classifList" into "Dictionary<Guid, String>". You have to modify like this :

private void AddToClassifList(TrackedList<Guid> listId)

if (listId != null)

foreach (Guid taxaId in listId)

if (taxaId != Guid.Empty && !classifList.Contains<Guid>(taxaId))

classifList.Add(taxaId, TaxonomyManager.GetManager().GetTaxon(taxaId).Title);

Now on your created events you can find category :

Event event1 ....

//return true if a specific category item exist on an event

event1 .Organizer.TaxonExists("Categories", GuidOfCategory1)

Hi,

if your thumbnail is a custom field you can get it like this :

String NameOfCustomField = "thumbnail";

eI.GetValue(NameOfCustomField)
