Accessing elements between forms

If you are writing a Windows Forms App, one way to do it is to create a property for the textbox on your Form2, like this.

public string TextBoxValue
{
   get
   {
      return TextBox1.Text;
   }
   set
   {
      TextBox1.Text = value;
   }
}

And then, you can set values on your Form1, like this.

Form2 f2 = new Form2();
f2.TextBoxValue = "YourValue";
f2.Show();
