If I understand your question correctly, you have the taxonomy id and want to display all the content within that taxonomy. If that is not what you are after, then please clarify your question, and I'll try to help as best I can.
I find that the added baggage that comes along with a widget can sometimes make it hard to test for correct API and server control usage. For that reason, I'd recommend starting off with a simple ASPX page.
<ektron:ContentModelSource ID="contentModelSource" runat="server">
</ektron:ContentModelSource>
<ektron:ContentView ID="ContentView1" runat="server" ModelSourceID="contentModelSource" EktronCustomTemplate="Ektron_ContentList_Template">
</ektron:ContentView>
Normally, the examples you'll find for the templated server controls show the declarative syntax for setting the filters, where you put them right into the ASPX markup - right inside the ContentModelSource control. Something like:
<TaxonomyFilters>
<ektron:ContentTaxonomyFilter Field="Id" Operator="EqualTo" Value="208" />
</TaxonomyFilters>
(More examples here and here.)
But for what it sounds like you want to accomplish, you need to define the filters via code. This code does just that:
protected long TaxonomyId
{
get
{
long id;
long.TryParse(Request.QueryString["id"], out id);
return id;
}
}
protected bool IsRecursive
{
get
{
bool recursive;
bool.TryParse(Request.QueryString["recursive"], out recursive);
return recursive;
}
}
protected void Page_Init(object sender, EventArgs e)
{
if (TaxonomyId > 0)
{
if (IsRecursive)
{
var tm = new TaxonomyManager();
var td = tm.GetItem(TaxonomyId);
if (td != null)
{
var pathFilter = new ContentTaxonomyFilter();
pathFilter.Field = ContentTaxonomyProperty.Path;
pathFilter.Operator = CriteriaFilterOperator.StartsWith;
pathFilter.Value = td.Path;
contentModelSource.TaxonomyFilters.Add(pathFilter);
}
}
else
{
var filter = new ContentTaxonomyFilter();
filter.Field = ContentTaxonomyProperty.Id;
filter.Value = TaxonomyId.ToString();
filter.Operator = CriteriaFilterOperator.EqualTo;
contentModelSource.TaxonomyFilters.Add(filter);
}
}
}
A couple of things to note:
The TaxonomyId is a property. I did this so that there would be an easy point of comparison between this simple ASPX page and a custom widget where your property would be decorated with the WidgetDataMember attribute.
The code is in the Page_Init event handler. That is important. Page_Load is too late in the page's lifecycle. I assume this would also be true in the context of a widget.
My code for when IsRecursive == true is not necessarily optimized. You could get reasonable performance by turning on caching in the FrameworkAPI, but the idea of calling the api to get the taxonomyData and then using that to set the filter for the content seems a little off. Ideally, the ContentTaxonomyFilter would have a "Recursive" property.
