Functionality
This button navigates the user to an external destination when clicked, based on the Action Type set to "Open URL" and the URL entered in Control properties. Additional Parameters can be configured to pass form data along in the URL if needed, and standard label/formatting options apply as with other buttons.
Use Case
For this example, a button is needed to navigate the user to Google. To create a URL button, the main thing that is needed is the destination URL. The process for configuring the Launch URL button is as follows:
Place a Launch URL button on the form
Navigate to the Control properties
Name and label this button
Add additional formatting as necessary
Enter the destination URL
Navigate to Inbox to check to see if the link is working properly
Note: Launch URL buttons only function in Inbox, not in Preview mode.
Logic
Just like other string fields, Launch URL Buttons can have Enabled, Read Only, and Visible calculations. Additional Parameters can be configured to pass form data along in the URL if needed.
