Use the Loop and File Upload controls to limit how many files may be uploaded to a Screen. Though the File Upload control allows multiple files to be uploaded, any number of files can be uploaded if this feature is enabled. Therefore, this example provides a way to limit the number of files that may be uploaded to a Screen.
Follow these steps to design a Screen that limits how many files may be uploaded:
- 2.From the Data Source setting, select the New Array of Objects option.
- 3.In the Default Loop Count setting, enter how many files by default that may be uploaded to this Screen. 3 is the default setting.
- 4.Select the Allow additional loops option to allow additional files be uploaded to this Screen. By default this setting is not selected, which would prevent additional files be uploaded.
- 5.Do not enter a visibility rule in the Visibility Rule setting so that the Loop control always remains visible.
- 6.Specify other settings in the Loop control as necessary. These settings do not affect how this example functions.
- 7.Add a File Upload control to the Loop control by dragging it into the Loop control.
- 8.Configure the File Upload control as necessary. These settings do not affect how this example functions.
- 9.Add a Submit Button control to this Screen. Ensure not to add the Submit Button control inside the Loop control.
- 11.Reference this Screen from a Process model or as an editable Screen in a Collection.
Download this Screen to your computer, and then import it.
