Uploading and downloading a file using the File Uploader control

This example shows how you can use File Uploader with a storage bucket and with a file field of an entity.

1. In your app, add a Storage Bucket and a Data Service entity that has file fields.
2. Add a File Uploader and a Button control.
3. Create a variable of type AppsFile and name it "SB_file_var'. Use this variable to store the file downloaded from the storage bucket.
4. Add the Upload file to Storage Bucket rule to the Clicked on event of the button control.
   1. In the File to upload field, reference the file uploaded through the File Uploader control, as follows:

      MainPage.FileUploader.Value

   2. In the Storage bucket field, reference the Orchestrator storage bucket that you previously added to your app.
   3. Optionally, in the When completed field, you can add a Show Message rule to inform you the uploading completed successfully.
5. Add the Download file from Storage Bucket rule to the Clicked on event of the button control.
   1. In the Storage bucket field, reference the Orchestrator storage bucket that you previously added to your app.
   2. In the File Name (with extension) field, write the name of the file your users should download.
   3. In the Assign file to app variable, reference the previously created variable "SB_file_var".
   4. Optionally, in the When completed field, you can add a Show Message rule to inform you the downloading completed successfully.
6. Add a Label control to your app.
   1. In the Text field of the control, reference the name of the downloaded file, as follows:

      SB_file_var.Name

      - where "SB_file_var" is the variable used to store data about the downloaded file.

7. Run your app and upload a file using the File Uploader control. Click the button.

A success message should appear at the top of your screen informing you the upload/download completed successfully. Now check the storage bucket in Orchestrator and you should see the file you uploaded using the File uploader control.

Simultaneously, clicking the button downloaded the file indicated in the Download file from Storage Bucket rule to your local device and stored its data to a variable. The Label control displays the name of the downloaded file.
