Hi Steve,

i just found out that Xamarin Studio fails to build the application for an IOS device (the previous tests i did against the simulator) with the new IG.Unified.dll

with the following error:

/Users/gdo/Projekte/MikMobileUnified/MTOUCHTASK: Error MT5211: Native linking failed, undefined Objective-C class: _OBJC_CLASS_$_IGGridViewSingleFieldDynamicColumnDataSourceHelper. If '_OBJC_CLASS_$_IGGridViewSingleFieldDynamicColumnDataSourceHelper' is a protocol from a third-party binding, please check that it has the [Protocol] attribute in its api definition file, otherwise verify that all the necessary frameworks have been referenced and native libraries are properly linked in. (MT5211) (MIKmobile)

Fore sure i switched back to the previous Version, removed the AddFixedRows() call and verything was fine.

Maybe that helps ...

Best regards

Gernot

Hi Steve,

thanks for the quick response!

But when do this with my overwritten DataSourceHelper

dsh.AddFixedRow(datagrid, new IGRowPath(1, 0, IGGridViewFixedRowDirection.IGGridViewFixedRowDirectionTop));

I get the following Exception

So i think, i have to overwrite some functions

Best regards

Gernot
