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;} }}

TechnologyDAL层的方法

namespace BTAppDAL{ public class TechnologyDAL {public DataTable GetList（int startPage, int pageSize, string where, string orderby）{ string strSql = string.Format（"SELECT a.TechnologyId,a.TechnologyName,a.Summarize,a.Effect,a.MainPoint,a.AppropriateArea,a.Attention,a.CreateTime,a.CreatUser,a.UpdateTime,b.Name FROM Technology AS a 
" +"left join Sys_DepInfo AS b ON a.Depinfo_Id=b.Id 
" +"where a.IsActive="1" and {0} ", where）; string proc = "proc_CommonPagerWithStatement"; SqlConnection con = SqlDbHelper.Connection; SqlParameter[] sp = { new SqlParameter（"@intStartIndex", startPage）,new SqlParameter（"@intPageSize", pageSize）, new SqlParameter（"@varStatement", strSql）,new SqlParameter（"@varSortExpression", orderby+" DESC"） }; DataTable dt = SqlDbHelper.GetDataSet（proc, sp, con）; return dt;}public int GetCountList（string where）{ int countRecord = 0; string strSql = string.Format（"select COUNT（TechnologyId） as countRecord from（SELECT a.TechnologyId,a.TechnologyName,a.Summarize,a.Effect,a.MainPoint,a.AppropriateArea,a.Attention,a.CreateTime,a.CreatUser,a.UpdateTime,b.Name FROM Technology AS a 
" +"left join Sys_DepInfo AS b ON a.Depinfo_Id=b.Id 
" +"where a.IsActive="1" and {0} ） as c", where）; SqlConnection con = SqlDbHelper.Connection; try {if （con.State == System.Data.ConnectionState.Closed） con.Open（）;DataTable dt = SqlDbHelper.GetDataTable（strSql）;if （dt.Rows.Count > 0） countRecord = int.Parse（dt.Rows[0]["countRecord"].ToString（））; } catch （Exception） {throw; } finally {if （con.State == ConnectionState.Open）{ con.Close（）;} } return countRecord;}public DataTable GetModel（string TechnologyId）{ string strSql = string.Format（"SELECT a.TechnologyId,a.TechnologyName,a.Summarize,a.Effect,a.MainPoint,a.AppropriateArea,a.Attention,a.CreateTime,a.CreatUser,a.UpdateTime,b.Name FROM Technology AS a 
" +"left join Sys_DepInfo AS b ON a.Depinfo_Id=b.Id 
" +"where a.IsActive="1" and a.TechnologyId = "{0}" ", TechnologyId）; DataTable dataTable = SqlDbHelper.GetDataTable（strSql）; return dataTable;}public DataTable GetPicture（string TechnologyId）{ string strSql = string.Format（"SELECT TOP 5 a.Files_Id,a.Files_Name,a.Files_Path FROM dbo.Com_Files AS a 
" +"LEFT JOIN dbo.Technology AS b ON a.ForeignKey_Id=b.TechnologyId 
" +"WHERE b.IsActive=1 and a.ForeignKey_Id = "{0}" ", TechnologyId）; DataTable dataTable = SqlDbHelper.GetDataTable（strSql）; return dataTable;} }}

ExpertInfoBLL 层的方法

 public DataTable GetDepInfo（）{ DataTable dTable = dal.GetDepInfo（）; return dTable;}

ExpertInfoDAL层的方法

 public DataTable GetDepInfo（）{ try {StringBuilder str = new StringBuilder（@"SELECT Id,Name FROM dbo.Sys_DepInfo WHERE Is_Active="1" AND DepinfoType="1""）;DataTable data = SqlDbHelper.GetDataTable（str.ToString（））;if （data.Rows.Count > 0）{ return data;}else{ return null;} } catch （Exception） {return null; }}

在页面加载的时候调用DropDownListDataBind（）方法
触发RadioButtonList的点击事件

 protected void RadioButtonList1_SelectedIndexChanged（object sender, EventArgs e）{string Id;Id = RadioButtonList1.SelectedValue;GetDataBind（Id）;}

既可以实现点击某个单选按钮，并触发事件。
