As of WorkflowGen version 7.20.0, you can choose to show or hide the Edit and/or Delete buttons in GridView form fields. To do this, check or uncheck the Show edit button and/or Show delete button options on the Appearance tab in the GridView settings panel.
To hide the buttons in earlier versions of WorkflowGen, you’ll need to edit the .NET code. See the Form Designer: How to hide the update, edit, or delete buttons in a GridView article for instructions on how to do this.
