No valid report source

[Former Member]

Hi,

When printing a report the first page prints fine, but when I want to navigate to the 2nd page or if I want to use grouping the "No valid report source" error message is displayed.

I'm using Visual Studio 2010 Professional and Crystal Reports Version for Visual Studio 2010 (13.0.0.99).

The code behind sample:

TempSQLString = "SELECT CustomerNumber, CustomerName FROM Customers WHERE CustomerStatus = 'ACTIVE'"

Dim TempDataAdapter As New SqlDataAdapter()

TempDataAdapter.SelectCommand = New SqlCommand(TempSQLString, TempConnection)

TempDataAdapter.Fill(TempDataSet, "TempCRSource")

Dim TempCrystalReport As New crTempReport

TempCrystalReport.SetDataSource(TempDataSet.Tables(0))

crvTempReport.ReportSource = TempCrystalReport

I've read a number of posts all over the net, but none of them really presents a solution with the majority still being unresolved. Can anyone please help?

Thanks in advance!

Looks like a web app(?)

And you are doing post backs \ putting the report in session?

And you've seen KB #1525432 - Could not load file or assembly 'file:///<Path>crdb_adoplus.dll' or one of its dependencies?

Hi Ludek,

Yes, it is a web app.

Yes, there are postbacks, and yes, I did try the solution proposed with - still no improvement.

I've tested KB#1525432 and still it shows the same error.

Anything else I could try?

Hi all,

Thanks to those who looked into this problem. I managed to get it addressed even though I still have a couple of minor issues, which I'l research today.
