do not coding by yourself, there is an exist example.
Code:
private void NewFields(int pageno)
{
Page page = m_doc.GetPage(pageno);
DocFont dfont = m_doc.NewFontCID("Times", 8);//embed in horizontal writing
ResFont rfont = page.AddResFont(dfont);
PageContent content = new PageContent();
content.Create();
content.SetFillColor(0);
page.ObjsStart();
float rect[] = new float[4];
float font_size = 20;
float box_size = 20;
float text_gap = 5;
//2 radiobox for male/female.
rect[0] = 20;
rect[1] = 630;
rect[2] = rect[0] + box_size;
rect[3] = rect[1] + box_size;
content.TextBegin();
content.TextSetFont(rfont, font_size);
content.TextMove(rect[0] + box_size + text_gap, rect[1] + font_size * 0.15f);
content.DrawText("Male");
content.TextEnd();
page.AddFieldRadio(rect, "radsex", "Male", null, null);
