access from one of this childs to a method in Master Form

Question

I am a user of c# visual studio 2005. I have a principal MDI Master Form that launch mdi childrens. I need to access from one of this childs to a method in Master Form. How can I do this? Must I use delegates? Static methods? (if static my problem is that I can call Master's method from child but this method isn't able to accessing form controls.)

Hi You could use Application.OpenForms[] In the example below I have 2 Forms. One Mdiform (Form1) and one child.(Form2) And I created a public non-static method Form1.Test1() just for test purposes. Form2.cs private void button1_Click(object sender EventArgs e) { Form1 form1 = (Form1)Application.OpenForms[0]; form1.Test1(); }
