充分利用单选按钮列表中选择价值 [英] Getting selected value from RadioButtonList

问题描述

新的ASP.NET（C＃）...

New to ASP.NET(C#)...

我有我的网页上一个单选按钮列表，它通过数据绑定填充

I have a RadioButtonList on my page that is populated via DataBinding

<asp:RadioButtonList ID="rb" runat="server">
</asp:RadioButtonList>
<asp:Button Text="Submit" OnClick="submit" runat="server" />

我如何获取用户在我的提交方法选择的单选按钮的价值？

How do I get the value of the radio button that the user selected in my "submit" method?

推荐答案

在ASPX code会是这个样子：

The ASPX code will look something like this:

 <asp:RadioButtonList ID="rblist1" runat="server">

    <asp:ListItem Text ="Item1" Value="1" />
    <asp:ListItem Text ="Item2" Value="2" />
    <asp:ListItem Text ="Item3" Value="3" />
    <asp:ListItem Text ="Item4" Value="4" />

    </asp:RadioButtonList>

    <asp:Button ID="btn1" runat="server" OnClick="Button1_Click" Text="select value" />

和背后的code：

protected void Button1_Click(object sender, EventArgs e)
        {
            string selectedValue = rblist1.SelectedValue;
            Response.Write(selectedValue);
        }
