I read the documentation of Essential PDF and nothing indicates that form fields can be renamed. Is that right? If yes, do you have plans to implement this feature?

Hi Martel,

Thank you for your interest in Syncfusion products.

Currently we do not have support to rename the form fields. However we will create a feature request report for this implementation. Please create an incident in the Direct-Trac for the follow up of this feature.

Please let us know if you have any questions.

Has this feature been added yet? It still doesn't seem like it can be done.

Is there a woraround to this?

Hi Carl, 
Thank you for your update. 
Yes, we can rename the existing form field by using the SetName method. Also, we have created a simple sample for demonstrating the same, please refer the code snippet and sample below. 
            //Load the existing PDF document 
            PdfLoadedDocument ldoc = new PdfLoadedDocument(Server.MapPath("/App_Data/test1.pdf")); 
            //Load the PDF form 
            PdfLoadedForm lform = ldoc.Form; 
            foreach (PdfLoadedField field in ldoc.Form.Fields) 
                if (field is PdfLoadedTextBoxField) 
                    //Set the new name of the field 
                    (field as PdfLoadedTextBoxField).SetName(field.Name + "_renamedField"); 
                else if (field is PdfLoadedCheckBoxField) 
                    //Set the new name of the existing filed 
                    (field as PdfLoadedCheckBoxField).SetName(field.Name + "_renamedField"); 
            //Save the document 
            ldoc.Save("output.pdf", Response, HttpReadType.Open); 
Please let us know if you have any concern.
