On vb.net error on system.drawing.fontFamily.GetName 'Parameter is not valid'

Question

That dataGridView is in tab0 of a tabControl that has 2 more tabs with a dataGridView fed with same method each one. When application starts, all apparently runs correct, but when changing to tab1 and returning to tab0 again, application returns that error recovered from immediate window:

I'm trying to discover which line of my code causes this Error

Thanks for help

Answer 1

I would say your error is there :

OBSVCOM.My.MyApplication.Main(String\[\] Args) in :line 83\</StackTrace\>\<ExceptionString\>System.ArgumentException: Parameter is not valid.

On line 83 (main). But without your code, I can't tell more.
