Multi Table Crystal Reports Project

Last Updated on August 21, 2023 by Humera Hallari

The following is the source code of the project how to create a Crystal Reports report using two or more database tables. With this method we will be able to display the contents of several tables into one Crystal Reports page.

With this method we no longer need to make many reports for each table. However, it should be noted that creating a report with a multi table must pay attention to the database column. Because when we display data we need a relationship between tables that can only be done if each table has one or more columns of the same type.

Here you can download the project and also the source code of how to display reports with multitables using Crystal Reports and VB.NET.

You can modify the code freely as per your needs. Projects can be opened with Visual Studio 2019. For more details it is recommended to watch the guide video from part 1 about this Crystal Report.

Source Code

Imports MySql.Data.MySqlClient
Public Class Form2
    Dim con1 As MySqlConnection
    Dim cmd1 As MySqlCommand
    Dim adp1 As MySqlDataAdapter
    Dim dtb As New DataTable
    Dim dtbsub As New DataTable
    Sub viewdata()
        cmd1 = New MySqlCommand("select * from detailreport", con1)
        adp1 = New MySqlDataAdapter(cmd1)
        adp1.Fill(dtb)
        cmd1 = New MySqlCommand("select * from subreport", con1)
        adp1 = New MySqlDataAdapter(cmd1)
        adp1.Fill(dtbsub)
        con1.Close()
        con1.Dispose()
    End Sub
    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        dtb.Clear()
        dtbsub.Clear()
        con1 = New MySqlConnection("server=localhost;user=root;password='';database=dbvb")
        Dim myrpt As New multireport
        viewdata()
        myrpt.Database.Tables("detailreport").SetDataSource(dtb)
        myrpt.Database.Tables("subreport").SetDataSource(dtbsub)
        CrystalReportViewer1.ReportSource = Nothing
        CrystalReportViewer1.ReportSource = myrpt
    End Sub
