BuiltinActions :: BrowseManyFiles - Browse many files

The action pops up with a file dialog for selecting any number of files from the file system. The intention of this dialog is using the file in read-only mode, i.e. one cannot enter a file name, which does not exist. Nevertheless, files can be opened later on by the application in write mode.

The results (file names) are stored one by one to the control, which is associated with the action. Since each iteration step will overwrite the previous file name in the control, the result should be evaluated in the doBeforeDataStore () event handler as shown in the example below.
