在PDFPCell iTextSharp中添加单选按钮

Question

我正在尝试在itextsharp的pdfpcell中添加一个单选按钮。这是我的代码：

var rf1 = new RadioCheckField(writer, new Rectangle(10,10), "cellRadioBox", "Yes");
rf1.Checked = true;
rf1.CheckType = RadioCheckField.TYPE_CHECK;
PdfFormField field = rf1.CheckField;

var radioEvents = new iTextSharp.text.pdf.events.FieldPositioningEvents(writer, rf1.GetRadioGroup(false,true));
radioCell.CellEvent = radioEvents;
table.AddCell(radioCell);

这会创建一个文本块而不是单选按钮。也许是因为使用了FieldPositioningEvents。我不知道如何为单选按钮创建自定义单元格事件。有没有简单的方法呢？

Answer 1

Rectangle rect = new Rectangle(10,10);
var rf1 = new RadioCheckField(writer, rect, LANGUAGES[i], "on");
rf1.CheckType = RadioCheckField.TYPE_CHECK;
PdfFormField field = rf1.CheckField;
