First of all from the Properties Box I'd change the Modifiers property of the GroupBox from private to internal. Secondly you'll need a reference to the Form which contains the GroupBox. Suppose the class name of that form is Form1. Then you can get a reference to the form (and hence the GroupBox) from anywhere else in the application as follows: Form1 f1 = (Form1)System.Windows.Forms.Application.OpenForms[Form1]; GroupBox gb = f1.groupBox1; // or whatever you've called it Finally you can access individual controls in the GroupBox in the following fashion: TextBox tb = (TextBox)gb.Controls[textBox1];
