public class QueryPage : System.Web.UI.Page{protected System.Web.UI.WebControls.TextBox txtStaDate;protected System.Web.UI.WebControls.TextBox txtEndDate; .../// <summary>/// 开始时间/// </summary>public string StaDate{get{ return this.txtStaDate.Text;}set{this.txtStaDate.Text = value;}}/// <summary>/// 结束时间/// </summary>public string EndDate{get{ return this.txtEndDate.Text;}set{this.txtEndDate.Text = value;}}....private void btnEnter_Click(object sender, System.EventArgs e){Server.Transfer("ResultPage.aspx");}}
在显示查询结果页面(ResultPage.aspx):
public class ResultPage : System.Web.UI.Page{ private void Page_Load(object sender, System.EventArgs e) {
//转换一下即可获得前一页面中输入的数据QueryPage queryPage = ( QueryPage )Context.Handler;
Response.Write( "StaDate:" );Response.Write( queryPage.StaDate );Response.Write( "<br/>EndDate:" );Response.Write( queryPage.EndDate ); }}
如果有许多查询页面共用一个结果页面的设置方法: 在这种方式中关键在于“ QueryPage queryPage = ( QueryPage )Context.Handler; ”的转换,只有转换不依赖于特定的页面时即可实现。 如果让所有的查询页面都继承一个接口,在该接口中定义一个方法,该方法的唯一作用就是让结果页面获得构建结果时所需的参数,就可实现多页面共享一个结果页面操作!1、先定义一个类,用该类放置所有查询参数:
/// <summary>/// 结果页面中要用到的值/// </summary>public class QueryParams{private string staDate;private string endDate;
/// <summary>/// 开始时间/// </summary>public string StaDate{get{ return this.staDate;}set{this.staDate = value;}}/// <summary>/// 结束时间/// </summary>public string EndDate{get{ return this.endDate;}set{this.endDate = value;}}}
2、接口定义:
/// <summary>/// 定义查询接口。/// </summary>public interface IQueryParams{/// <summary>/// 参数/// </summary>QueryParams Parameters{get;}}
3、查询页面继承IQueryParams接口(QueryPage.aspx):
/// <summary>///查询页面,继承接口/// </summary>public class QueryPage : System.Web.UI.Page, IQueryParams{protected System.Web.UI.WebControls.TextBox txtStaDate;protected System.Web.UI.WebControls.TextBox txtEndDate;
private QueryParams queryParams; .../// <summary>/// 结果页面用到的参数/// </summary> public QueryParams Parameters{get{return queryParams;}}....private void btnEnter_Click(object sender, System.EventArgs e){//赋值queryParams = new QueryParams();queryParams.StaDate = this.txtStaDate.Text;queryParams.EndDate = this.txtEndDate.Text
Server.Transfer("ResultPage.aspx");}}
别外的页面也如此设置 5、接收页面(ResultPage.aspx):public class ResultPage : System.Web.UI.Page{ private void Page_Load(object sender, System.EventArgs e) {
QueryParams queryParams = new QueryParams();IQueryParams queryInterface;//实现该接口的页面if( Context.Handler is IQueryParams){queryInterface = ( IQueryParams )Context.Handler;queryParams = queryInterface.Parameters;}
Response.Write( "StaDate:" );Response.Write( queryParams.StaDate );Response.Write( "<br/>EndDate:" );Response.Write( queryParams.EndDate ); }}
