The following members return FileManagerDetailsCustomColumn objects:
When the FileManagerSettingsFileList.View property is set to Details , the file list displays a grid containing information about files. A default grid column can display the following file information (specified by the FileManagerDetailsColumn.FileInfoType property): name, last write time, size, and thumbnail.
Add an object of the FileManagerDetailsCustomColumn type to the FileManagerFileListDetailsViewSettings.Columns collection to display custom information in the grid. To populate a custom column with cell values, use the ASPxFileManager.DetailsViewCustomColumnDisplayText event.
You can use the ASPxFileManager.DetailsViewCustomColumnHeaderFilterFillItems event to provide custom filter items displayed within a filter dropdown for the custom column.
To learn more, see the Custom Columns topic.
