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.
