Is it not bad OO design to directly access the parent controls from the child? Wouldnt using a property be a more appropriate method?
It maintains encapsulation and allows you to validate the value passed from the child:
public partial class Parent : Form
//could add get method to allow child to read from parent control
public string TextBox1Value
//check input is valid
if (value == "Valid")
//write value to control
TextBox1.Text = value;
public partial class Child : Form
private void WriteToParent (string Text)
//retrieve parent and cast to parent type then send text to property
((Parent)this.MdiParent).TextBox1Value = "Valid";
