Preview a file that has been uploaded from a previous Task via a File Upload control in that Request.
The File Preview control allows the Request participant to configure a file preview that has been previously uploaded to that Request via a File Upload control. After adding the control in the Screen to where to display the file preview, configure the Name setting value for the File Upload control from which to preview the file it uploaded to that Request.
This control is only available for the following Screen types:
After adding a control to a Screen page, you may move it to another location on that page such that it is above or below other controls placed on that page. A control cannot be moved to another Screen page.
Follow these steps to move a control to another location on that Screen page:
Place your cursor anywhere on the control not displaying the Duplicate Control
or Delete Control
Hold your cursor, then drag the control above or below other controls on that Screen page. Screen Builder previews where the control would display on the page based on how you position the control above or below other controls. If the control cannot be placed in a location because your cursor is above an existing control or too far to the left or right of the page, the
icon displays in the preview.
Place the control at the location on the page you want it. The other control(s) on the page automatically adjust position.
Copy the Control with its Settings
Copying a control also copies the current settings of that control. The copied control displays below other controls placed on that Screen page.
. The control copies with its current settings, and then displays below other controls placed on that page.
As a best practice, after copying a control, change the Variable Name setting value for the copied control to its own unique variable value. Otherwise, in-progress Requests that use this Screen read from and send data to both controls.
Edit the default Variable Name setting value for this control if necessary. The Variable Name setting value represents data in this control during Requests. Ensure that the Variable Name setting value is a unique name from other controls in this Screen and contains at least one letter. This is a required setting.
Enter the Name setting value for the File Upload control from which to preview its file that was previously uploaded to this Request. Do not use mustache syntax when entering the File Upload control's Name setting. This setting has no default value.
Advanced Panel Settings
Click the control while in Design mode, and then click the Advanced panel that is on the right-side of the Screen Builder canvas.
Below are settings for the Line Input control in the Advanced panel:
Enter the value to represent this control in custom CSS syntax when in Custom CSS mode. As a best practice, use the same CSS Selector Name value on different controls of the same type to apply the same custom CSS style to all those controls.
