Hi Folks,
i am happy NUCLIOS 2015 supports this feature and there is also a sample - but pure C.
Would it be possible to get a c# sample ?
It seems, i would have to overwrite some IGGridViewDataSourceHelper functions, but i don't get it ...
Thanks in advance
Gernot
Hi Gernot,
Are you currently using the IGGridViewDatSourceHelper in your project?
If so, you don't need to override anything.
There is a new method, gridView:addFixedRowAtPath: in C# the name is AddFixedRow
so you would call it as dish.AddFixedRow(gridView, pathOfRowToFix)
Thats it.
Hope this helps.

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

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 ...
He Gernot,
Sorry for the delayed response. You're right something is indeed broken.
We'll get that fixed for you, so you can take advantage of the new features.
Thanks for the report.
I'm getting this similar error when compiling for a device (works on simulator):
MTOUCH: Error MT5211: Native linking failed, undefined Objective-C class: _OBJC_CLASS_$_IGGridViewSingleFieldDynamicColumnDataSourceHelper.

Any suggestions?
