Hello,

I am trying to run an iOS Application using the DataGrid Control, however I am getting the following error:

System.ArgumentNullException: Value cannot be null.

Parameter name: method

Also, I am getting the same error with the downloaded example in the DataGrid Tutorial (GettingStarted Project)

Full Output.

Thank you very much for the response.

That was my problem, I had the link behavior property to Link all assemblies, changing it to Link SDK assemblies only solve the problem and I was able to run my application.

Thanks for the help!
