Solution 2

1) Name that DataTable
2) Add it in DataSet
3) Add DataSet as a source of a crystal report

Hi! If you are using Datagridview put this code on your print button.

Dim dt As New DataTable

       With dt
           .Columns.Add("id")
           .Columns.Add("name")
           .Columns.Add("address")
       End With


       For Each dr As DataGridViewRow In Me.dgv_list.Rows
           dt.Rows.Add(dr.Cells("id").Value, dr.Cells("name").Value, dr.Cells("address").Value)

       Next

       Dim rptDoc As CrystalDecisions.CrystalReports.Engine.ReportDocument
       rptDoc = New cr_logslist
       rptDoc.SetDataSource(dt)

       frm_report_viewer.CrystalReportViewer1.ReportSource = rptDoc
       frm_report_viewer.ShowDialog()
       frm_report_viewer.Refresh()
       frm_report_viewer.Dispose()

Note: Change cr_loglist with the name of your Crystal Report file.

Hope it helps.
