You have a reference to the form that you want to pass the data to, so add a property or method to the form so that you can pass data to it.

What's happening in Form1 constructor?
If Form1 constructor loads data and populates dataGridView1 your code should work (not the best way to do it, but it will work), otherwise you will have IndexOutOfRange exception because dataGridView1 does note have any rows.

Could you please be more specific about problems you have with your solution?
