水晶报表的翻页显示问题

[happyxhl]

开始点查询，可以得到报表的第一页，可是点报表中的后一页按钮，页回却不显示数据，显示的是开始出现的设计时的CystalReportViewer控件，本来初学ASP。NET，请各位帮下忙看看。代码如下：
using System;
using System.Collections;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Web;
using System.Web.SessionState;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.HtmlControls;
using CrystalDecisions.CrystalReports.Engine;

namespace WebRpt_SN
{
/// <summary>
/// Rpt1Frm 的摘要说明。
/// </summary>
public class Rpt1Frm : System.Web.UI.Page
{
protected System.Web.UI.WebControls.TextBox tbDateFrom;
protected System.Web.UI.WebControls.TextBox tbDateTo;
protected System.Web.UI.WebControls.Button bOK;
protected CrystalDecisions.Web.CrystalReportViewer crptv;
protected System.Data.OleDb.OleDbCommand cmdRpt1;

private void Page_Load(object sender, System.EventArgs e)
{
// 在此处放置用户代码以初始化页面
}

private void bOK_Click(object sender, System.EventArgs e)
{
cmdRpt1.Connection = MyGlob.OleDbConn;
System.Data.OleDb.OleDbDataAdapter daRpt1=new System.Data.OleDb.OleDbDataAdapter(cmdRpt1);
DataSet1 myds=new DataSet1();
daRpt1.Fill(myds,"产值");
crpt1 myrpt=new crpt1();
myrpt.SetDataSource(myds);
crptv.ReportSource=myrpt;
crptv.RefreshReport();
}

}
}

没人告诉我啊，不知道你们是不知道呢还是嫌分少，24

[zhangxishi]

private void Page_Load(object sender, System.EventArgs e)
{
bOK_Click(sender, e);
}
在load时间内加入代码

UP

[cnjack]

private void Page_Load(object sender, System.EventArgs e)
{
bOK_Click(sender, e);
}

应该不是你程序的问题，而是水晶报表你没有设置好吧

[woainin]

对，你要把数据帮定代码放在page_load里！

[zhoujianfan]

一定要放在page_load裡嗎，那不是每次都要讀取數據庫　　有沒有其它的辦法

[zhoujianfan]

另報表上部的頁數顯示
水晶報表上的頁碼數字　怎么是 2/2+ 而不是 當前頁/總頁數 呢

[daisylh]

要放在page_load中
水晶報表上頁碼數字顯示如2/2+,可在水晶報表中顯示第幾頁/共幾頁即可正常

[cgl1992]

mznumber1(浮躁) 正解格，
水晶報表上頁碼數字顯示如2/2+, 的问题，需要拖入一个special field : PAGE N OF M
就可以
