use events/delegate. when grid is changed on form 1 event fires to notify form2 of the selected data. form1 where your grid sits. this will send data back to form 2: public partial class Form1 : Form { public delegate void mydelegate(string message); public event mydelegate myEvent; public Form1() { InitializeComponent(); } private void button1_Click(object sender EventArgs e) { myEvent(some data); } } form2 which calls form1 and expects to receive data from it: public partial class Form2 : Form { private int counter = 0; public Form2() { InitializeComponent(); } private void button1_Click(object sender EventArgs e) { Form1 myform = new Form1(); myform.myEvent += respondEvent; myform.Show(); } private void respondEvent(string message) { counter++; this.button1.Text = counter.ToString(); } }
