Access a Form's Control from another Form

We Can access a Form's Control such as TextBox,ComboBox,datagridview etc. From another Form by passing current Form Object into another Form via an Overloaded constructor.

Ex:
In form 1

Form2 f1 = new Form2(this);
f1.ShowDialog();


then In Form2

Form1 form1;

public Form2(Form1 f)
{
InitializeComponent();
this.form1 = f;

}

we can easily access form1's TextBox like

form1.textBox1.Text="Hi,This is Form2";

Note : Modifiers property of Form1's TextBox1 should be declared as Public.

Thank you
