Example
This demo shows how to display or play back a file in a multimedia format (flash, audio, video) when the file’s filename extension is not specified. In this case, you need to know the file’s MIME type and manually set the ASPxObjectContainer.ObjectType property to a corresponding value (Audio, Video, Flash, or Image).
