動態創建的Radiobutton列表未激活onselected

Question

有一個動態創建的radiolist按鈕，目的是在單擊單選按鈕時觸發。 這是一個動態面板

    pnldynamic.Controls.Add(lbl);
                                RadioButtonList rd = new RadioButtonList();

                                foreach (CustomerFile cu in allCustomerFile)
                                {
                                       rd.Items.Add(cu.ApplicationNumber.ToString());

                                }
    rd.AutoPostBack = true;
           rd.SelectedIndexChanged += new EventHandler(radioButton_CheckedChanged);
        pnldynamic.Controls.Add(rd);

以下是關於選定索引更改的radiobuttonlist的事件處理程序

       private void radioButton_CheckedChanged(object sender, EventArgs e)
        {
            RadioButton btn = sender as RadioButton;
            txtReferenceNumber.Text = btn.Text;
                   }

選擇radiobuttonlist時，函數中的斷點不會被擊中

Answer 1

嘗試這個：

RadioButtonList rd = new RadioButtonList();
foreach (CustomerFile cu in allCustomerFile
{
    rd.Items.Add(cu.ApplicationNumber.ToString());
}
rd.AutoPostBack = true;
rd.SelectedIndexChanged += new EventHandler(radioButton_CheckedChanged);
pnldynamic.Controls.Add(rd);
