My application uses the following code to fill a datagrid named TabReportList

mySqlDataTable1.Active = true;
TabReportList.DataSource = mySqlDataTable1;
TabReportList.DataMember = "tabelname";
TabReportList.DataBind();

This works fine in Version 3.5. After upgrade to 4.0 I get runtime errors on DataBind: NullReferenceException

What has changed so my appliction does not work any longer? Please help.
I use DOT.Net 2.0 Framework with VS2005 C#

Trying to reproduce this problem, I came accross another one. We need to investigate this detailed. I'll let you know our progress as soon as possible.

Thanks for your fast feedback, I will have a look here for for more information coming up

By the way: My DataGrid-Component is the AdvWebGrid from TMS Software, perhaps you know his component

I would say this is not just a "by the way" thing. I am downloading their pack to try it.

Anything new in this case?

I get still get the error in Version 4.00.10.

Again: The error only occurs if using version 4, go back to version 3.5 (by copy the dll in the bin directory) still work. What has been changed?

We have fixed this problem for you.
New build will be available in the beginning of the next week.

New build of MySQLDirect .NET 4.00.12 is available now!

Thanks a lot, the 4.00.12 works fine.

You are welcome.
