Question

我正在尝试动态地将radiobuttons添加到表单中（因此我可以在用户单击按钮时更改其值）但随后我添加了各个按钮的位置信息，它们根本不再显示。我可以在表单上看到GroupBox的轮廓，以及每边几百个像素。

private void AddQ1()
{
   questionBox = new System.Windows.Forms.GroupBox();
   questionBox.Location = new System.Drawing.Point(1200, 250);
   questionBox.Size = new System.Drawing.Size(400, 700);
   questionBox.Text = "To What extent is this person... striking a pose?";

   RadioButton radioButton1;
   for (int i = 1; i < 6; i++)//opt 1,2,3,4,5
   {
       radioButton1 = new System.Windows.Forms.RadioButton();
       radioButton1.CheckedChanged += new EventHandler(radioButton_CheckedChanged);
       radioButton1.Tag = i.ToString();
       radioButton1.Text = i.ToString();
       radioButton1.Location = new System.Drawing.Point(1200, (250+(10*i)));
       questionBox.Controls.Add(radioButton1);
       rbList.Add(radioButton1);
   }
   Controls.Add(questionBox);
}

Answer 1

位置是指向控件 relative 的左上角到其容器左上角的Point。试试

radioButton1.Location = new System.Drawing.Point(0, (250+(10*i)));

Answer 2

上面的代码中不会显示单选按钮的位置。 location属性与容器

是关系的

RadioButton定位在Form上
