To avoid disrupting your existing code you can do something like this in Form2: Form1 f1 = (Form1)Application.OpenForms[Form1]; DataGridView dgv = (DataGridView)f1.Controls[dataGridView1]; Button btn1 = (Button)f1.Controls[button1]; Button btn2 = (Button)f1.Controls[button2]; You can now control the DGV and buttons from Form2 using the 'dgv'  'btn1' and 'btn2' references.

Doing it the other way around should be easier as you're presumably opening form2 from form1: // add this private field to form1 private Form2 f2; // in method where you open form2 something like: f2 = new Form2(); // assign reference to field f2 not to a local variable f2.Show(); // in some other method in form1 Button btn1 = (Button)f2.Controls[button1]; // assuming form2 has a button1 btn1.PerformClick(); // or whatever you want to do

Perhaps I misunderstand what you need to do and since you already have an answer I won't spend time on this but it seems to me that one possibility would be to make a UserControl from one or both forms.
