I have the following function that changes my crystal reports default 'MainReport' to 'XYZ' text. What I cannot figure out to do is how to add another tab page to the report programatically and then run sql to return the data in that tab page...

In a nutshell, I have:

        Dim rpt As New MyReport
        ' where the ds is a dataset from an sql query
        rpt.SetDataSource(ds.Tables(0))

        CrystalReportViewer.ReportSource = rpt
        SetTabPage()
        CrystalReportViewer.Visible = True


   Private Function SetTabPage() As Boolean

        Dim I As Integer

        Do While I < CrystalReportViewer.Controls.Count
            If TypeOf (CrystalReportViewer.Controls(I)) Is CrystalDecisions.Windows.Forms.PageView Then
                Dim J As Integer
                Do While J < CrystalReportViewer.Controls.Count
                    If CType(CrystalReportViewer.Controls(I).Controls(J), System.Windows.Forms.TabControl).TabPages.Count > 0 Then
                        CType(CrystalReportViewer.Controls(I).Controls(J), System.Windows.Forms.TabControl).TabPages.Item(0).Text = "XYZ"
                        'CType(CrystalReportViewer.Controls(I).Controls(J), System.Windows.Forms.TabControl).TabPages.Add(???????????)
                        Exit Do
                    End If
                Loop
                Exit Do
            Else
                CrystalReportViewer.Controls(I).Visible = False
            End If
        Loop
    End Function


******** The spot with the ?????? is where I would like the TabPage added ****

The second piece is the how do I direct the dataset to a tab page on the Crystal report ...

Thanks!

Can you explain a little bit more detail what you're trying to do?

The link sent by mlmcc is not for VB .NET .. I am using Crystal Descisions 9. plus I am not using the CRViewer. I am using CrystalReportViewer.


For frodoman:
I am trying to add a tab to CrystalReportViewer that is on a form. The CrystalReportViewer has a default tab called 'MainReport'. I have found how to change to Tab Text for MainReport to 'XYZ' as you can see in my question. The report displays data from a dataset. This all works fine.

1) I would like to be able to add another tab to the CrystalReportViewer.

After I know how to do this ...

2) I would like to know how to direct dataset1 to the first tab and dataset2 to the second tab.

This is a VB .NET application.
Thanks!

That's what I thought but I wanted to make sure.  Unfortunately you can't do that - that would require modifying the code of the CRViewer control itself which is a proprietary component.

What you can do is to use a normal tabstrip control in vb.net and have a single viewer (obviously outside of the tabstrip) and then when the tab is changed you simply change the reportsource of the viewer.  Alternatively you can put a different viewer control inside each tab on the vb.net tabstrip and have each control pointed to a different report.

The tab you see that says "MainReport" is an internal working of the viewer control.  If you for example have an on-demand subreport and you drill into it then you'll see two tabs - MainReport and SubReport1.  You can then use these tabs to navigate between the main and sub report(s).  

Since the answer to question #1 is that you can't do it, it makes question #2 irrelevant.  Obviously if you go with one of the alternatives above then you simply show a different viewer or update the viewer to point to a different report -- it's not a matter of directing a dataset to a specific tab.
