点击提交 如何遍历RadioButton 并输出选中按钮的Text<table>
<tr>
<td>
<asp:DataList ID="ddlPreview" runat="server" Width="80%" Font-Size="12px">
            <ItemStyle Wrap="False" />

Answer 1

private void button1_Click_1(object sender, EventArgs e)
        {
            string str = " ";
            for (int i = 0; i < this.groupBox1.Controls.Count; i++)
            {
                RadioButton cb = this.groupBox1.Controls[i] as RadioButton;
                if (cb.Checked == true)
                {
                    str = cb.Text.ToString() + str;
                }
            }或foreach (RepeaterItem ri in Repeater1.Items)
{
  foreach (Control ctl in ri.Controls)
  {
  RadioButton radTemp = ctl as RadioButton;
  if (radTemp != null)
  {
  if (radTemp.Checked)
  {
  Response.Write(radTemp.Text);
  }
  }
  }
}
            MessageBox.Show(str);
        }

Answer 2

protected void Button1_Click(object sender, EventArgs e)
        {
            for (int i = 0; i < this.Controls.Count; i++)
            {
                foreach (object item in Page.Controls[i].Controls)//遍历当前当前页面上的控件
                {
                    if (item is RadioButton)
                    {
                        RadioButton  lb = (System.Web.UI.WebControls.RadioButton )item;
                        Response.Write（lb.Text）;//显示
                    }
                }
            }
        }
上面的代码写在提交按钮敲击事件下，（跟批量给控件赋值差不多）
