Handling an Upload control by programming

Overview

The Upload control is used to upload one or more files.

The Upload control can be handled by programming. To do so, use the name of the Upload control ("Send" or "Add" button).

The Uploadxxx functions of WLanguage can also be used to handle an Upload control. See the list of functions for upload management for more details.

Managing Drag and Drop of files to an Upload control (HTML5)

Versions 17 and later
The browsers that support HTML5 (like Firefox and Chrome) allow you to Drag and Drop the files to the Upload control.

The "Details" tab in the Upload control description window ("Send" or "Add" button) is used to manage this feature. The "GUI" tab in the Upload control description window ("Send" or "Add" button) is used to manage this feature.

For an Upload control used to upload several files, the control on which the Drag and Drop operation can be performed corresponds by default to the list of the Upload control.

For an upload control used to upload a single file, we advise you to create a Static control displaying for example "Drop the file to upload here", then define this Static control as the control where the file will be dropped.

You also have the ability to modify the Upload control supplied by default:

Delete the initialization code of the static control ("STC_FileUpload" control).
In the "Details" tab of the Upload control, define the "STC_FileUpload" static control as being the receiving control.
Modify (if necessary) the default text of the static control. For example: Drop a file here or click "Send...".
Reinitialize the static control after the upload in the event "After receiving the uploaded files":

STC_File_Upload = "Drop a file here or click ""Send..."""

For an Upload control used to upload several files proposed by default, the control on which Drag and Drop can be performed corresponds by default to the cell of Upload control.
