问题描述

我的问题是我知道如何从单个表中检索数据并将其绑定到Crystal Report，并使用Crystal Report Viewer，我可以通过直接单击表单上的按钮直接打印它.

对于单个表，代码如下:
按下按钮时发生的事件:

my problem is i know how to retrive a data from single table and bind it to crystal report and using crystal report viewer i can directly print it using directly button clicking on my form


but i have problem that is how can i retrive a data from more than one table and used it..

On Button click event:

Call openconnection()
        str = "SELECT * from New_Case_Id_Master where CaseId=" & s_no & ""
        da = New SqlDataAdapter(str, cn)
        ds.Clear()

        da.Fill(ds, "New_Case_Id_Master")
        'MsgBox(ds.Tables("New_Case_Id_Master").Rows.Count)
        cn.Close()
        'print directly using button click
        Dim objRpt As New CrystalReport_for_FrontDesk
        objRpt.SetDataSource(ds.Tables("New_Case_Id_Master"))
        CrystalReportViewer1.ReportSource = objRpt
        CrystalReportViewer1.PrintReport()
        CrystalReportViewer1.PrintReport()
        CrystalReportViewer1.Refresh()
