Manipulating Upload controls programmatically
The Upload control is used to upload one or more files. Upload controls can be manipulated programmatically. To do so, use the name of the Upload control ("Send" or "Add" button). Managing Drag and Drop of files to an Upload control (HTML5) The browsers that support HTML5 (like Firefox and Chrome) allow you to Drag and Drop the files to the Upload control. The "UI" 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 proposed by default, the control on which Drag and Drop can be performed corresponds by default to the cell of Upload control. Upload control properties Several WLanguage properties are available for the Upload control. The main properties are as follows: | | | Count | Allows you to find out the number of files found in an Upload control. | | Multi-selection | Used to find out and modify the mode for selecting files in an Upload control. | | NameBrowserFile | Identifies the original name of the file to be uploaded on the user's computer. This property is only available for multi-file Upload controls. | | NameServerFile | Allows you to find out the name of the uploaded file found on the server. This property is only available for multi-file Upload controls. | | TypeFiles | Enables you to view and modify the file filter proposed in the Upload control file picker. | | Value | Allows you to find out and modify the list of files found in the Upload control. |
