I'd recommend using the ContentTaxonomyCriteria with the ContentManager.
long smartFormId = 42;
long taxonomyId = 127;
bool isRecursive = true;
var cm = new ContentManager();
var taxonomyCriteria = new ContentTaxonomyCriteria();
taxonomyCriteria.AddFilter(ContentProperty.XmlConfigurationId, CriteriaFilterOperator.EqualTo, smartFormId);
taxonomyCriteria.AddFilter(taxonomyId, isRecursive);
var content = cm.GetList(taxonomyCriteria);
UPDATE
The ContentData
object has a property called XmlConfiguration
. When the content is based on a smartform, this property will be non-null and have a positive (non-zero) Id: content[0].XmlConfiguration.Id
for example.
I often add an Extension Method to my code that will tell me whether a given ContentData is based on a smart form:
public static class ContentDataExtensions
{
public static bool IsSmartFormContent(this ContentData content)
{
return content != null && content.XmlConfiguration != null && content.XmlConfiguration.Id > 0;
}
}
That way I can take a content (or list of content) and check it very quickly in code to see if it's based on a smartform or not:
foreach (var contentData in contentList)
{
if (contentData.IsSmartFormContent())
{
// Do smart-form stuff here...
}
}
Of course, if your content is coming from the framework api and you used a criteria object that is selecting based on a specific XmlConfigurationId, then in theory you wouldn't have to use that, but it still comes in handy quite often.
