You need to use an EventHandler In the form f3 (sending the value) insert the following code... //Variable declaration public event EventHandler SendEvent; //Method protected void onSendEvent(object send) { SendEvent(send, EventArgs.Empty); } On the change event (ie. selected_index_change, click_event) insert the following code this.onSendEvent(value); //this event expects an object of any sort... you will need to know the type of object it is when you try accessing it from form f2(the listener) Now insert the following code in f2(the listener form) //This is where you insert the code that is to happen.... private void Test_EventSent(object sender, EventArgs e) { MessageBox.Show("You sent me: " + sender.ToString()); //mytextbox.Text = sender.ToString(); } If you need further help... let me know...

have a look here: http://dutch17.digitalus.nl/~admin26/~minimoose/forms.txt this shows the principal behind the method used. There's different ways of doing it, but this will work as well. Note that this is typed off the top of me hat, tis not tested. so there may be some type-o's in it.
