We’re showing/hiding a form section based on a radio button. If the user fills the section, then unchecks the button, we clear all TextBox fields from code behind, so the data isn’t submitted with the form. But the WorkflowFileUpload that’s in the section, if the user uploaded a file before hiding the section, will still upload the file into process data. I want to effectively click the Delete button for the WorkflowFileUpload control from code behind. It looks like there’s some jQuery event handler that’s doing… something on that button click, but I can’t figure out what, or how to otherwise remove the uploaded file before submitting the form. Ideas?
