获取控件的属性

介绍：由于要对属于同一组的单选按钮进行格式设置，那么不能使用RadioButtonList了。但是使用多个RadioButton，设置为同一组后，怎么获取单选按钮组中的CHECKED的按钮，实现代码如下：

 1using System;
 2using System.Data;
 3using System.Configuration;
 4using System.Collections;
 5using System.Web;
 6using System.Web.Security;
 7using System.Web.UI;
 8using System.Web.UI.WebControls;
 9using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;

public partial class _Default : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
            string rbtn_id = Get_CheckBox_Checkd();
            if (rbtn_id != string.Empty)
            {
                Response.Write(this.Page.FindControl(rbtn_id).ID);
            }
    }

    protected string Get_CheckBox_Checkd()
    {
        string rbtn_name = string.Empty;
        //控件ID的集合
        string[] rbtn_temp = new string[] { "RadioButton1","RadioButton2","RadioButton3"};
        foreach(string rbtn_ID in rbtn_temp)
        {

            RadioButton rbtn = (RadioButton)this.Page.FindControl(rbtn_ID);
            if (rbtn.Checked)
            { 
                rbtn_name = rbtn.ID;
                break;
            }
            else
            { 
                rbtn_name=string.Empty;
            }
        }
        return rbtn_name;
    }
}

 1using System;
 2using System.Data;
 3using System.Configuration;
 4using System.Collections;
 5using System.Web;
 6using System.Web.Security;
 7using System.Web.UI;
 8using System.Web.UI.WebControls;
 9using System.Web.UI.WebControls.WebParts;
10using System.Web.UI.HtmlControls;
11
12public partial class _Default : System.Web.UI.Page
13{
14    protected void Page_Load(object sender, EventArgs e)
15    {
16        //if (!Page.IsPostBack)
17        //{
18            string rbtn_id = Get_CheckBox_Checkd();
19            if (rbtn_id != string.Empty)
20            {
21                Response.Write(this.Page.FindControl(rbtn_id).ID);
22            }
23
24        //}
25    }
26
27    protected string Get_CheckBox_Checkd()
28    {
29        string rbtn_name = string.Empty;
30        string[] rbtn_temp = new string[] { "RadioButton1","RadioButton2","RadioButton3"};
31        foreach(string rbtn_ID in rbtn_temp)
32        {
33
34            RadioButton rbtn = (RadioButton)this.Page.FindControl(rbtn_ID);
35            if (rbtn.Checked)
36            { 
37                rbtn_name = rbtn.ID;
38                break;
39            }
40            else
41            { 
42                rbtn_name=string.Empty;
43            }
44        }
45        return rbtn_name;
46    }
47}
