Use Enabled property of the TextBox:

 

if(textBox1.Text.Lenght > 0)
   textBox1.Enabled = false;
else
   textBox1.Enabled = true;

On KeyPress event of Textbox you can check the condition and if its true/false you can prevent user from typing, have a look below:

    private void Textbox1_KeyPress(object sender, KeyPressEventArgs e)
    {
      try
      {
        if (YourCondition == true)
        {
          e.Handled = false;// false won't accept the key
        }
        else
          e.Handled = true;// true would accept the key pressed

      }
      catch (FormatException ex)
      {
        MessageBox.Show(ex.Message);
      }
    }
