I was making a code for printing Datagridview all value(Scroll Able Form) to Crystal Report. I have search over the internet, at least i have the code to print.

Private Sub prtbtn_Click(sender As Object, e As EventArgs) Handles prtbtn.Click
        Dim ds As New DataSet
        Dim dt As New DataTable()
        dt = TryCast(datagridview1.DataSource, DataTable)
        ds.Tables.Add(dt) <<Error
        Printview.report1.SetDataSource(ds)
        Printview.rptview.ReportSource = Printview.report1
        Printview.rptview.Refresh() 'Refresh the report.
    End Sub

But, when i tried to click. I got

'table' argument cannot be null.

Does anyone know how to solve it?

Sorry for the link, i dont know what it means, cause i was newbie to crystal report. Beside that i have tried to add my code,

     Dim dt As New DataTable
        Dim dgvrow As System.Windows.Forms.DataGridViewRow
        Dim dgvcol As System.Windows.Forms.DataGridViewColumn
        For Each dgvcol In Me.datagridview1.Columns
            dt.Columns.Add(dgvcol.Name)
        Next
        For Each dgvrow In Me.datagridview1.Rows
            dt.Rows.Add(dgvrow)
        Next
        Dim i As Integer = 0
        Dim j As Integer = 0
        For i = 0 To Me.datagridview1.Rows.Count - 2
            For j = 0 To Me.datagridview1.Columns.Count - 2
                dt.Rows(i).Item(j) = Me.datagridview1.Rows(i).Cells(j).Value.ToString()
            Next
        Next
        ds.Tables.Add(dt)
        Printview.CryRpt1.SetDataSource(dt)<<error here

        Printview.Show()

        Printview.rptview.Refresh()

But, i got error. "The report has no tables."
Also, the processing is taking much time even i have PC corei3
