最近討論區很多人在問crystal report的問題
小弟就多做一些範例,分享給大家呀.

首先準備好北風資料庫,下載

接下來先新增一個xsd檔(NORTHWND.xsd),當作Crystal Report的資料結構,如下圖所示(Products資料表)

再新增一個Crystal Report檔,資料庫專家選【專案資料→ADO.NET資料集→加入Products】,之後就是編輯報表了,如下圖所示

asp.net(c#)

GridViewCrystalReport.aspx

GridViewCrystalReport.aspx.cs

using System; using System.Data; using System.Configuration; using System.Collections; using System.Web; using System.Web.Security; using System.Web.UI; using System.Web.UI.WebControls; using System.Web.UI.WebControls.WebParts; using System.Web.UI.HtmlControls; public partial class GridViewCrystalReport : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { } protected void btnSearch_Click(object sender, EventArgs e) { if (this.txbProductName.Text.Trim() == "") { //使用沒條件的SqlDataSource this.GridView1.DataSourceID = this.SqlDataSource2.ID; } else { //使用有條件的SqlDataSource this.GridView1.DataSourceID = this.SqlDataSource1.ID; } } protected void btnReport_Click(object sender, EventArgs e) { DataTable dt = new DataTable(); if (this.GridView1.DataSourceID == this.SqlDataSource1.ID) { dt = ((DataView)this.SqlDataSource1.Select(DataSourceSelectArguments.Empty)).ToTable(); } else { dt = ((DataView)this.SqlDataSource2.Select(DataSourceSelectArguments.Empty)).ToTable(); } //create CrystalReport object CrystalDecisions.CrystalReports.Engine.ReportDocument report = new CrystalDecisions.CrystalReports.Engine.ReportDocument(); //load report report.Load(Server.MapPath("CrystalReport.rpt")); //set data report.SetDataSource(dt); //export report.ExportToHttpResponse(CrystalDecisions.Shared.ExportFormatType.Excel, Response, true, "report.xls"); } }

執行結果：
1.查詢結果

2.滙出Excel
