When you use DataSource, the data is bound to the DataGridView.
Here is an excellent article explaining data binding:

I thank you for comment.But i to met other state.For example i used byte array and this byte array assigment to other byte array.I change values of Second byte array then first byte array change values.So both change values of variables when i just change one variable value.As if 2 variable bind to each other.
How do i prevent this case.?
I thank you...

When you use Array2 = Array1; you do not get a copy, but a pointer to Array1 instead.
Use the Array.CopyTo() method to create a new array.

Thanks RickZeeland.
I used that method "CopyTo()".But all the same forced each other.
