I\'ve created a user control with some buttons. When you click a button in the UserControl the BackColor of the button changes:
private void button1(object send
You can get a reference to the parent form using this
Form parentFrm = (this.Parent as Form);
You can then access controls on the parent Form, by either making the public or finding the control by its name
Button aButton = (Button)parentFrm.Controls["btnName"];
if (aButton != null)
aButton.Enabled = true;
