The System.Windows.Forms.VisualStyles.FilenameProperty enumeration represents the names of image files that are used to draw visual style elements. The System.Windows.Forms.VisualStyles.FilenameProperty values are used as an argument in the VisualStyleRenderer.GetFilename(FilenameProperty) method to specify which file name property to retrieve for the element that the System.Windows.Forms.VisualStyles.VisualStyleRenderer currently represents.
