Master _ Detail connection is failed

Irvine · Post by **Irvine** » Sat 31 May 2008 07:05

Hello,

I have a big problem.
I develop new software by VS2008 and use PostgreSQL data accass package.

When I create new form what contains a lot of controls and I would like to try create Master - Detail relation, it doesn't work.
I can see only one tables datarows.

If I use Microsoft VS2008 component than the master-detail connection is ok.

Why?
How can I find one example?
Help Me, please?

Hello,

Please check the following samples in the Start menu for the master-details relation:
Core Lab PostgreSQLDirect for .NET2 -> Samples -> WinForms
or
Core Lab PostgreSQLDirect for .NET2 -> Samples -> Web
The number of controls should not interact with PostgreSQLDirect .NET.
Let me know if the problem is solved.

Regards,
Alexey.

Thank You your advice.
I tried compile the sample project, but I receive a lot of error message.

Hello Irvine,

The samples were originally build in Visual Studio 2005.
When Visual Studio 2008 uses conversion wizard, it creates ReportDataSet.Designer.cs file.
Please delete this file and rebuild the project.
