the line you are doing something wrong is Highlighted here in orange color
To get a value from another form

• On the File menu, point to New and then click Project.
  
• In the New Project dialog box, in the Templates pane, click Windows Forms Application, and then click OK.
  A new Windows Forms project opens.
  
• From the Toolbox, drag one TextBox and one Button control onto the form.
  
• In Solution Explorer, right-click the project, click Add, and then click New Item.
  In the Add New Item dialog box, in the Templates pane, click Windows Form, and then click Add.
  A new Windows Form (Form2) opens.
  
• From the Toolbox, drag one TextBox control onto the form.
  
• Change the Text property of the TextBox control to Sample text. The first form will read and display this property.
  
• Change the Modifiers property of the TextBox control from Private to Public to enable other forms to access this control.
  
• In Solution Explorer, right-click Form1.cs, and then click View Designer.
  
• In the form, double-click the button to create a Click event handler.
  
• Before the button1_Click event handler, add the following code to create an object that enables access to the components and properties of Form2:

private Form2 otherForm = new Form2();

11.In the button1_Click event handler, add the following code to get the value from the text box on Form2 and assign it to the text box on Form1:

textBox1.Text = otherForm.textBox1.Text;

• Press F5 to run the program.
  
• The program starts and the form appears. When you click the button on Form1, the text from the text box on Form2 appears in the text box on Form1

so you were not talking about static text in the textbox.So my method would work only on Labels..etc which have text set during designer time itself.Try the below,
In Form1.cs:

private Form2 otherForm;
private void GetOtherFormTextBox()
{
    textBox1.Text = otherForm.TextBox1.Text;
}

In Form2.cs:

public TextBox TextBox1
{
    get
    {
        return textBox1;
    }
}

}

if you still aren't understanding this here is a tip:
Don't expose controls outside of the form to which they belong.

Instead, define public properties that allow you to get at information
on the form, and name the property according to what it returns:

public class Form1
{
private TextBox textbox1;
... etc. ...
 
public string FirstName
{
get { return this.textBox1.Text; }
set { this.textBox1.Text = value; }
}

}
