File Uploader

Max file size - The maximum file size users can upload. The recommended maximum file size is 10 MB.
Allowed file types - The file types users can upload. Use "," to separate file extensions. For example, if you write .jpg, .png, .svg, only these file types are allowed to be uploaded. The . symbol is not mandatory when listing the file types.
Helper text - The help text to be displayed at runtime.
Tooltip - The text to be displayed when an app user hovers over the control. Use this to provide additional information on the control.
Label - The display text of the control.
Required - If true, app users must provide data in the control. To mark the control as mandatory at runtime, an asterisk * is added after the label text.
Custom error message - The text to be displayed if the Required property is set to true and the control is left empty.
Hidden- If true, hides the control at runtime.
Disabled - If true, disables the control at runtime.

Note:

The File Uploader control can upload only one file at a time.
Apps in a mobile browser do not support native camera-based photo uploads. Instead, save the photo to your device, then upload the saved file using the File Uploader control.

Control Alignment - By default, inherits the parent alignment. A different alignment other than the parent can be set. To default back to the parent alignment, deselect the overridden options.

Note: The alignment is dependent on the layout selected for the parent (Vertical vs Horizontal).

Label Placement - By default, the label is set to be displayed on top of the control, at the left side. You can place it to the left of the control, on the same line. The Label Width property configures how wide the label should be, and the Space between property sets the distance between the label and the control.
Font - The font attributes for both the label and the input text, such as font family, size, color, or style (Bold, Italic and Underline). By default, the control inherits the font family of the immediate parent container which is indicated by the keyword "Inherited".
Margin - The margin of the control. By default, a margin of 4px is set. Top/Bottom and Left/Right margin properties are combined. These properties can be detached using the Link button at the right side of the Margin section.
Size - The width and height of the control. By default, the size is set to auto. To set minimum or maximum values, click the three dot icon (...).
