Question

在下面提到的代码中，我将属性“value”添加到单选按钮。我需要知道如何将单选按钮'value'属性设置为字符串。

提前致谢。

protected void Page_Load(object sender, EventArgs e)
{
    RadioButton rdoAuthModeSingleFactor = new RadioButton();
    rdoAuthModeSingleFactor.Text = authModeObj["AuthenticationModes"].ToString();
    string authModeIdVal = authModeObj["AuthenticationModeId"].ToString();
    rdoAuthModeSingleFactor.GroupName = "AuthModes";
    rdoAuthModeSingleFactor.ID = "AuthModeRdoID";
    rdoAuthModeSingleFactor.Attributes.Add("Value", authModeIdVal);
    plhldrAuthModes1.Controls.Add(rdoAuthModeSingleFactor);
}

protected void btnAuthModeSave_Click(object sender, EventArgs e)
        {
    //Here iam using placeholder functionalities
    // radio button object name is rdo
            string authenticationModeCheckedVal = rdo.Text;  // how to get value of radio button instead of text
    }

Answer 1

对于网络表单：

<asp:RadioButtonList ID="rdogender" runat="server" RepeatLayout="Flow">
    <asp:ListItem Value="Male">Male</asp:ListItem>
    <asp:ListItem Value="Female">Female</asp:ListItem>
</asp:RadioButtonList>

并点击某些按钮

string value=rdogender.SelectedItem.Value.ToString();

希望你理解并为你工作。

Answer 2

string strResult = rdotest.Attributes["Value"];

Answer 3

尝试 rdo.SelectedValue 而不是 rdo.Text

将Asp单选按钮属性（值）设置为字符串
