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 \\n\" + \"left join Sys_DepInfo AS b ON a.Depinfo_Id=b.Id \\n\" + \"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 \\n\" + \"left join Sys_DepInfo AS b ON a.Depinfo_Id=b.Id \\n\" + \"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 \\n\" + \"left join Sys_DepInfo AS b ON a.Depinfo_Id=b.Id \\n\" + \"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 \\n\" + \"LEFT JOIN dbo.Technology AS b ON a.ForeignKey_Id=b.TechnologyId \\n\" + \"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。
以上就是本文的全部内容,希望对大家的学习有所帮助。
