I have a Repeater web part with a Filter attached to it. To populate a drop down list in the filter, I'm currently hard-coding the Document Types in there:
this.ddlResourceType.Items.Add(new ListItem("Webinar", "3455"));
This works for now, but I'd rather pull those types dynamically. In the Repeater control properties, under Content Filter > Document Types, I select the types of items that the repeater shows. This list is what I would like to be able to pull dynamically into the filter.
