Item
Item is a file or folder element within ASPxFileManager.
Use the FileManagerStyles.Item property to specify an item’s appearance style. To override these style settings, use the FileManagerStyles.File, FileManagerStyles.FileAreaFolder, and FileManagerStyles.Folder properties.
Templates
You can specify a common template used to display the content of all items in the file list when it is in thumbnails view mode. To do this, use the FileManagerFileListThumbnailsViewSettings.ItemTemplate property (see demo: Templates).
To specify a common template used to display the content of all items in a details view column, use the FileManagerDetailsColumn.ItemTemplate property.
