The IDocumentConverterControl Interface
For an .ascx control to function as a document converter configuration settings control, it must implement the IDocumentConverterControl interface.
The interface has the following members:
ContentType Gets or sets an SPContentType object that represents the content type of the source document to be converted.
RequiresConfiguration Gets a Boolean value that represents whether the document converter requires configuration.
ConverterSettings Gets or sets a String that represents the converter settings.
SectionDisplayTitle Gets a String that represents the page section in which this control is displayed.
