C# DataGridView and Multithreading Problem

I had some problems updating datagridview from another thread. Problem is in painting scrollbars (vertical one). One thing that is interesting is that everything is working fine if you start your program from VisualStudio debugger.

My first solution to this problem was: I've disabled scrollbars and application works fine.

After some time of research I've found solution to my problem!!!

to simplify there is two posibilities:

1. you have datagridview without binded datasource
Solution: use delegate to add rows, or update existing.

2. you have datagridview with binded datasource (for example datatable)
Solution: use delegate to update datatable/datasource,

if you dont now how, you can start from this article.
