本文實(shí)例為大家分享了RadioButtonList綁定后臺(tái)數(shù)據(jù)，觸發(fā)點(diǎn)擊事件的方法
首先前臺(tái)頁面放置一個(gè)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 后臺(tái)綁定數(shù)據(jù)
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綁定后臺(tái)數(shù)據(jù)
private void DropDownListDataBind()
{
ExpertInfoBLL bll = new ExpertInfoBLL();
DataTable dt = bll.GetDepInfo();
foreach (DataRow dr in dt.Rows)
{
RadioButtonList1.Items.Add(dr["Name"].ToString());//循環(huán)讀出數(shù)據(jù)庫的數(shù)據(jù)
}
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)
{
//這里寫解碼和數(shù)據(jù)庫返回結(jié)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);
//綁定數(shù)據(jù)
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);
}
//根據(jù)選擇單選按鈕的不同id,觸發(fā)事件
protected void RadioButtonList1_SelectedIndexChanged(object sender, EventArgs e)
{
string Id;
Id = RadioButtonList1.SelectedValue;
GetDataBind(Id);
}
}
}
TechnologyBLL 層的方法
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層的方法
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 層的方法
public DataTable GetDepInfo()
{
DataTable dTable = dal.GetDepInfo();
return dTable;
}
ExpertInfoDAL層的方法
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;
}
}
在頁面加載的時(shí)候調(diào)用DropDownListDataBind()方法
觸發(fā)RadioButtonList的點(diǎn)擊事件
protected void RadioButtonList1_SelectedIndexChanged(object sender, EventArgs e)
{
string Id;
Id = RadioButtonList1.SelectedValue;
GetDataBind(Id);
}
既可以實(shí)現(xiàn)點(diǎn)擊某個(gè)單選按鈕，并觸發(fā)事件。
以上就是本文的全部?jī)?nèi)容，希望對(duì)大家的學(xué)習(xí)有所幫助。
