Adding ComboBox to Pdf.Form and setting its value and other properties

When I use your example to add a comboBox and add its items, the comboBox value is not being set (the debugger reports "null").

In the code below, "field" is a TextBox. I want to replace it with a comboBox and set the comboBox's value to "Jeff."

pdfDocument.Form.Delete(field);

FormEditor formEditor = new FormEditor();
formEditor.BindPdf(pdfDocument);
formEditor.AddField(FieldType.ComboBox, field.FullName, "Jeff", page, (float)field.Rect.LLX, (float)field.Rect.LLY, (float)field.Rect.URX, (float)field.Rect.URY);

//add list items
formEditor.AddListItem(field.FullName, "Jeff"); //field.Value);
formEditor.AddListItem(field.FullName, "Some prior value");
this.pictureBoxPDFPage.Image = Utilities.PDFGetPageThumbnail(pdfDocument, thumbnailSize, page);

pdfDocument.Save("C:\\Junk\\ComboBox.pdf");

Note: The page image does not show a comboBox. It just looks like a blank spot in the document. Plus, there is no value.

I opened the saved document in Acrobat Pro. The comboBox is there. It has no border. I want a border, too. The items were there. The value is not set, and therefore, it is null.

How can I get:

1. The value to be set,
2. A border, and
3. The page image to show the comboBox?

Thanks.
