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:RadioButtonListrunat="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
namespaceBTApp
{
publicpartialclassTechnology:System.Web.UI.Page
{
stringId;
protectedvoidPage_Load(objectsender,EventArgse)
{
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
privatevoidDropDownListDataBind()
{
ExpertInfoBLLbll=newExpertInfoBLL();
DataTabledt=bll.GetDepInfo();
foreach(DataRowdrindt.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();
}
privatevoidGetDataBind(stringId)
{
//这里写解码和数据库返回结果
TechnologyBLLbll=newTechnologyBLL();
stringstrWhere="1=1";
if(Id!=""&&Id!=null)
{
strWhere+=string.Format("anda.Depinfo_Id='{0}'",Id);
}
AspNetPager1.RecordCount=bll.GetCountList(strWhere);
//绑定数据
DataTabledt=bll.GetList((AspNetPager1.CurrentPageIndex-1)*AspNetPager1.PageSize,AspNetPager1.PageSize,strWhere,"CreateTime");
this.Repeater1.DataSource=dt;
this.Repeater1.DataBind();
}
protectedvoidAspNetPager1_PageChanged(objectsender,EventArgse)
{
GetDataBind(Id);
}
//根据选择单选按钮的不同id,触发事件
protectedvoidRadioButtonList1_SelectedIndexChanged(objectsender,EventArgse)
{
stringId;
Id=RadioButtonList1.SelectedValue;
GetDataBind(Id);
}
}
}
TechnologyBLL层的方法
namespaceBTAppBLL
{
publicclassTechnologyBLL
{
TechnologyDALdal=newTechnologyDAL();
publicDataTableGetList(intstartPage,intpageSize,stringwhere,stringorderby)
{
DataTabledTable=dal.GetList(startPage,pageSize,where,orderby);
returndTable;
}
publicintGetCountList(stringwhere)
{
intrecord=dal.GetCountList(where);
returnrecord;
}
publicDataTableGetListShow(stringTechnologyId)
{
DataTabledTable=dal.GetModel(TechnologyId);
returndTable;
}
publicDataTableGetPicture(stringTechnologyId)
{
DataTabledTable=dal.GetPicture(TechnologyId);
returndTable;
}
}
}
TechnologyDAL层的方法
namespaceBTAppDAL
{
publicclassTechnologyDAL
{
publicDataTableGetList(intstartPage,intpageSize,stringwhere,stringorderby)
{
stringstrSql=string.Format("SELECTa.TechnologyId,a.TechnologyName,a.Summarize,a.Effect,a.MainPoint,a.AppropriateArea,a.Attention,a.CreateTime,a.CreatUser,a.UpdateTime,b.NameFROMTechnologyASa\n"+
"leftjoinSys_DepInfoASbONa.Depinfo_Id=b.Id\n"+
"wherea.IsActive='1'and{0}",where);
stringproc="proc_CommonPagerWithStatement";
SqlConnectioncon=SqlDbHelper.Connection;
SqlParameter[]sp={newSqlParameter("@intStartIndex",startPage),
newSqlParameter("@intPageSize",pageSize),
newSqlParameter("@varStatement",strSql),
newSqlParameter("@varSortExpression",orderby+"DESC")};
DataTabledt=SqlDbHelper.GetDataSet(proc,sp,con);
returndt;
}
publicintGetCountList(stringwhere)
{
intcountRecord=0;
stringstrSql=string.Format("selectCOUNT(TechnologyId)ascountRecordfrom(SELECTa.TechnologyId,a.TechnologyName,a.Summarize,a.Effect,a.MainPoint,a.AppropriateArea,a.Attention,a.CreateTime,a.CreatUser,a.UpdateTime,b.NameFROMTechnologyASa\n"+
"leftjoinSys_DepInfoASbONa.Depinfo_Id=b.Id\n"+
"wherea.IsActive='1'and{0})asc",where);
SqlConnectioncon=SqlDbHelper.Connection;
try
{
if(con.State==System.Data.ConnectionState.Closed)
con.Open();
DataTabledt=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();
}
}
returncountRecord;
}
publicDataTableGetModel(stringTechnologyId)
{
stringstrSql=string.Format("SELECTa.TechnologyId,a.TechnologyName,a.Summarize,a.Effect,a.MainPoint,a.AppropriateArea,a.Attention,a.CreateTime,a.CreatUser,a.UpdateTime,b.NameFROMTechnologyASa\n"+
"leftjoinSys_DepInfoASbONa.Depinfo_Id=b.Id\n"+
"wherea.IsActive='1'anda.TechnologyId='{0}'",TechnologyId);
DataTabledataTable=SqlDbHelper.GetDataTable(strSql);
returndataTable;
}
publicDataTableGetPicture(stringTechnologyId)
{
stringstrSql=string.Format("SELECTTOP5a.Files_Id,a.Files_Name,a.Files_PathFROMdbo.Com_FilesASa\n"+
"LEFTJOINdbo.TechnologyASbONa.ForeignKey_Id=b.TechnologyId\n"+
"WHEREb.IsActive=1anda.ForeignKey_Id='{0}'",TechnologyId);
DataTabledataTable=SqlDbHelper.GetDataTable(strSql);
returndataTable;
}
}
}
ExpertInfoBLL层的方法
publicDataTableGetDepInfo()
{
DataTabledTable=dal.GetDepInfo();
returndTable;
}
ExpertInfoDAL层的方法
publicDataTableGetDepInfo()
{
try
{
StringBuilderstr=newStringBuilder(@"SELECTId,NameFROMdbo.Sys_DepInfoWHEREIs_Active='1'ANDDepinfoType='1'");
DataTabledata=SqlDbHelper.GetDataTable(str.ToString());
if(data.Rows.Count>0)
{
returndata;
}
else
{
returnnull;
}
}
catch(Exception)
{
returnnull;
}
}
在页面加载的时候调用DropDownListDataBind()方法
触发RadioButtonList的点击事件
protectedvoidRadioButtonList1_SelectedIndexChanged(objectsender,EventArgse)
{
stringId;
Id=RadioButtonList1.SelectedValue;
GetDataBind(Id);
}
既可以实现点击某个单选按钮，并触发事件。
