Signature Control Settings

Add a control that displays a digital signature in Screens.

Control Description

The Signature control allows the Request participant to sign and her or his signature in a Screen. The entered signature automatically saves, but is not committed until the signer submits the Screen. The signer may undo the entered signature prior to submitting the Screen. The submitted signature is recorded as a PNG image that may be referenced from an Image control by referencing the Signature control's Variable Name setting value.

This control is only available for Form-type Screens. See Screen Types.

Package Required

To add a Signature control to a Screen, the Signature package must be installed.

Permissions Required

Your user account or group membership must have the following permissions to design a Screen unless your user account has the Make this user a Super Admin setting selected:

  • Screens: Edit Screens

  • Screens: View Screens

See the Screens permissions or ask your Administrator for assistance.

Add the Control to a Screen

Follow these steps to add this control to the Screen:

  1. View the Screen page to which to add the control.

  2. Drag the Signature icon into the Screen Builder canvas. Existing controls on the Screen Builder canvas adjust positioning based on where you drag the control.

  3. Place into the Screen Builder canvas where you want the control to display on the Screen.

  4. Configure the Image control. See Settings.

  5. Validate that the control is configured correctly. See Validate Your Screen.

Move the Control on the Page

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:

  1. 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.

Follow these steps to copy a control:

  1. Select the control to be copied.

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.

Delete the Control from a Screen

Deleting a control also deletes configuration for that control. If you add another control, it will have default settings.

Follow these steps to delete a control from a Screen page:

  1. Select the control to be deleted.
