ASP.NET中RadioButtonList绑定后台数据后触发点击事件

本文实例为大家分享了RadioButtonList绑定后台数据,触发点击事件的方法

首先前台页面放置一个RadioButtonList 控件

<asp:RadioButtonList runat="server" ID="RadioButtonList1" BorderStyle="None" RepeatColumns="3" CssClass=""
      RepeatLayout="Flow" AutoPostBack="true" OnSelectedIndexChanged="RadioButtonList1_SelectedIndexChanged">
    </asp:RadioButtonList>

.cs文件 后台绑定数据

namespace BTApp
{
 public partial class Technology : System.Web.UI.Page
 {
  string Id;
  protected void Page_Load(object sender, EventArgs e)
  {
   if (!IsPostBack)
   {
    AspNetPager1.PageSize = 10;
    if (Request.QueryString["Id"] != null)
    {
     Id = Request.QueryString["Id"];
    }
    else
    { Id = ""; }
    GetDataBind(Id);
    DropDownListDataBind();
   }
  }
  //RadioButtonList绑定后台数据
  private void DropDownListDataBind()
  {
   ExpertInfoBLL bll = new ExpertInfoBLL();
   DataTable dt = bll.GetDepInfo();
   foreach (DataRow dr in dt.Rows)
   {
    RadioButtonList1.Items.Add(dr["Name"].ToString());//循环读出数据库的数据
    
   }
   this.RadioButtonList1.DataSource = dt;
   this.RadioButtonList1.DataTextField = "Name";
   this.RadioButtonList1.DataValueField = "Id";
   this.RadioButtonList1.RepeatDirection = RepeatDirection.Horizontal;
   this.RadioButtonList1.DataBind();
  
  }
  private void GetDataBind(string Id)
  {
   //这里写解码和数据库返回结果
   TechnologyBLL bll = new TechnologyBLL();
   string strWhere = " 1=1 ";
   if (Id != "" && Id != null)
   {
    strWhere += string.Format(" and a.Depinfo_Id = '{0}'", Id);
   }
   AspNetPager1.RecordCount = bll.GetCountList(strWhere);
   //绑定数据 
   DataTable dt = bll.GetList((AspNetPager1.CurrentPageIndex - 1) * AspNetPager1.PageSize, AspNetPager1.PageSize, strWhere, "CreateTime");
   this.Repeater1.DataSource = dt;
   this.Repeater1.DataBind();


  }
  protected void AspNetPager1_PageChanged(object sender, EventArgs e)
  {
   GetDataBind(Id);
  }

//根据选择单选按钮的不同id,触发事件
  protected void RadioButtonList1_SelectedIndexChanged(object sender, EventArgs e)
  {
    string Id;
    Id = RadioButtonList1.SelectedValue;
    GetDataBind(Id);
  }
  
 }
}

TechnologyBLL 层的方法

namespace BTAppBLL
{
 public class TechnologyBLL
 {
  TechnologyDAL dal = new TechnologyDAL();
  public DataTable GetList(int startPage, int pageSize, string where, string orderby)
  {


   DataTable dTable = dal.GetList(startPage, pageSize, where, orderby);
   return dTable;
  }
  public int GetCountList(string where)
  {


   int record = dal.GetCountList(where);
   return record;
  }
  public DataTable GetListShow(string TechnologyId)
  {
   DataTable dTable = dal.GetModel(TechnologyId);
   return dTable;
  }
  public DataTable GetPicture(string TechnologyId)
  {
   DataTable dTable = dal.GetPicture(TechnologyId);
   return dTable;
  }
 }
}
