如何在RadioButtonList之间添加项目？

Question

我们有一个列表,它正在生成服务器端,然后使用<asp:RadioButtonList...它来显示它.

但是,我们如何在其中一个项目之后添加一些HTML？

我们的想法是,如果生成其中一个,就会生成一些"子"单选按钮.

谢谢

ASP.NET:

private void PopulateFollowUpRadioButtons(Order order)
        {
            //Based on the options selected while creating the order template populate the radio button list.
            if (order.OrderTemplate.fur01Visible)
                FolloupRadioButtonList.Items.Add(new ListItem(order.OrderTemplate.fur01Label, "1"));
            if (order.OrderTemplate.fur02Visible)
                FolloupRadioButtonList.Items.Add(new ListItem(order.OrderTemplate.fur02Label, "2"));
            if (order.OrderTemplate.fur03Visible)
                FolloupRadioButtonList.Items.Add(new ListItem(order.OrderTemplate.fur03Label, "3"));


            //If follow up option is already selected then select the option in the Follow Up Radio button control 
            if (order.FollowUpRoleId != null)
                FolloupRadioButtonList.SelectedValue = order.FollowUpRoleId.Value.ToString();
        }


<asp:RadioButtonList ID="FolloupRadioButtonList" CssClass="black" ForeColor="Black"  runat="server"></asp:RadioButtonList>

创建您自己的自定义radiobuttonlistcontrol:

Namespace Controls
    Public Class MyRadioButtonList
        Inherits RadioButtonList

        Protected Overrides Sub RenderItem(itemType As System.Web.UI.WebControls.ListItemType, repeatIndex As Integer, repeatInfo As System.Web.UI.WebControls.RepeatInfo, writer As System.Web.UI.HtmlTextWriter)
            writer.Write("<div>Extra content</div>")
            MyBase.RenderItem(itemType, repeatIndex, repeatInfo, writer)
        End Sub
    End Class

End Namespace

并使用它.

首先将控件注册到页面或用户控件:

<%@ Register Assembly="(projectnamespace)" Namespace="(projectnamespace).Controls" TagPrefix="cc1" %>

然后使用控件:

<cc1:MyRadioButtonList ID="rdolist" runat="server" />

它是服务器端的基本radiobuttonlistcontrol,所以只需像现在一样使用它.
