Question

怎样取得radiobutton的值

Answer 1

使用RadioButtonList,这个连分组都省了，直接用RadioButtonList.SelectedItem.Text取文本值，用RadioButtonList.SelectedValue取Value的值. 你上面那种写法,必须用for循环每一个RadioButton,还要判断哪个被选中,在取相应的文本。
页面端：
<Panel id= "Panel1" runat= "server ">
<asp:radiobutton id= "RadioButton1 " runat= "server " Text= "博士 " GroupName= "know "> </asp:radiobutton> <asp:radiobutton id= "RadioButton2 " runat= "server " Text= "硕士 " GroupName= "know "> </asp:radiobutton> <asp:radiobutton id= "RadioButton3 " runat= "server " Text= "本科 " GroupName= "know "> </asp:radiobutton> <asp:radiobutton id= "RadioButton4 " runat= "server " Text= "大专 " GroupName= "know "> </asp:radiobutton> <asp:radiobutton id= "RadioButton5 " runat= "server " Text= "中专 " GroupName= "know "> </asp:radiobutton> </Panel>
服务端：
private string GetSelectNoteValue()
{
Panel Panel1 = new Panel();
string strText = string.Empty;
for (int i = 1; i <= 5; i++)
{
RadioButton rbtn = (RadioButton)Panel1.FindControl("radioButton" + i.ToString());
if (rbtn.Checked)
{
strText = rbtn.Text;
break;
}
}
return strText;
}

建议你用RadioButtonList.
