Question

I am trying to group radiobuttons together with groupname property.. It doesnt work because of the naming convention in asp.net while rendering..

因此,我试图继承无线电台的控制权和压倒一切的无线电台,并自行控制。

it solved the grouping problem but its not taking care of viewstate for some reason... so all my radiobuttons are are viewstate-less..

我的法典如下:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Web.UI.WebControls;
using System.Web.UI;

namespace CustomControl
{
    public class GroupRadioButton : RadioButton
    {
        public GroupRadioButton()
            : base()
        { }

        protected override void Render(HtmlTextWriter writer)
        {
            base.Render(new GroupedRadioButtonTextWriter(writer,this.GroupName));
        }
    }

    public class GroupedRadioButtonTextWriter : HtmlTextWriter
    {
        private string groupName;

        public GroupedRadioButtonTextWriter(HtmlTextWriter baseWriter, string groupName) : base(baseWriter)
        {
            this.groupName = groupName;
        }

        public override void AddAttribute(HtmlTextWriterAttribute key, string value)
        {
            if (key == HtmlTextWriterAttribute.Name)
            {
                base.AddAttribute(key, this.groupName);
            }
            else
            {
                base.AddAttribute(key, value);
            }
        }
    }
}

谁能帮助?

我认为,鉴于以下事实,你滥用了你的时间:RadioButtonList是你应当使用的内容。
